SUMMARY:CBE Seminar: "Unlocking New Therapeutic Strategies by Reconstructing Cell Signaling Networks from the Ground Up" (Mohamad Abedi\, University of Washington\, Seattle)
DESCRIPTION:Abstract: \nImmunotherapies have achieved remarkable success in treating hematological cancers\, yet the solid tumor microenvironment remains a significant barrier to therapeutic breakthroughs. Machine learning (ML)-driven computational protein design offers a powerful approach to creating novel protein components tailored for specific functions. By combining ML-driven design with synthetic biology and immuno-engineering\, we have developed innovative tools to overcome therapeutic barriers within the tumor microenvironment while deepening our understanding of the biological systems involved. In the first half of this seminar\, I will introduce three new technologies developed using these approaches: (1) a receptor degradation platform to remodel the tumor microenvironment and enhance therapy\, (2) a novel class of receptors that sense soluble tumor markers and localize therapeutic activity\, and (3) de novo-designed many-to-many protein networks resembling mammalian signaling complexity. In the second half\, I will present a computational protein design pipeline that reconstructs cytokines from the ground up. This approach allows us to design cytokines with customizable receptor clustering geometries\, enabling precise exploration of their cell-specific effects and the ability to fine-tune their naturally pleiotropic activities. Furthermore\, this approach enabled us to transcend nature’s designs by creating entirely novel cytokines that cells have never encountered before\, thus unlocking new therapeutic opportunities to manipulate the tumor microenvironment and expand our understanding of the underlying signaling mechanisms.

SUMMARY:ESE Seminar - "A changing grid powered by the new generations of power conversion\, control\, and energy management"
DESCRIPTION:The electric grid is undergoing a transformative paradigm shift\, driven by sweeping changes in generation\, demand\, and energy storage. By 2035\, solar PV alone is expected to supply 40% of U.S. electricity\, with substantial additional contributions from wind\, geothermal\, and hydroelectric sources—creating a renewable-dominant energy landscape. Meanwhile\, electricity demand is accelerating due to rapid growth in electric vehicle (EV) charging\, data centers\, industrial manufacturing\, and universal electrification across sectors. By 2050\, EV charging is anticipated to represent 23% of the nation’s electricity demand. Energy storage system installations are also expanding to manage the variability of renewable sources\, support dynamic loads\, and ensure grid stability. \nThis seminar will discuss the pivotal role of high power\, high voltage\, and high frequency power converters in creating a flexible\, efficient\, and resilient grid. We will examine integration challenges for 15kV-class converters within the AC grid\, as well as the opportunities these converters present for real-time voltage stabilization\, frequency regulation\, and dynamic grid management. High-bandwidth converters are key enablers of a smart\, adaptable grid\, facilitating higher renewable penetration\, dynamic load management\, and enhanced compatibility with energy storage. A few projects on grid-connected power electronics will highlight how these advancements can drive the evolution of a robust and versatile grid architecture to meet the demands of a power electronics-driven energy future.

SUMMARY:BE Seminar - "The Neurobiology of Mistakes" (Becket Ebitz\, Université de Montréal)
DESCRIPTION:Humans and other animals do not always choose the most rewarding course of action\, even when we have ample time and computational resources.Why do we make mistakes? The noiseLab uses a combination of theoretical\, behavioral\, and neurobiological techniques to address this question. In this talk\, Dr. Becket Ebitz will discuss converging evidence that mistakes are the product of representational and temporal nonlinearities in neural activity that constrain our ability to make good decisions. The talk will argue that some of these nonlinearities have long-term adaptive benefits\, even when they fail to produce the best decision in the moment. \n

SUMMARY:LRSM Seminar: "Expanding Our Vision of Glasses: Physical Vapor Deposition Prepares Ultrastable and Anisotropic Materials"
DESCRIPTION:Glasses are generally regarded as disordered and the idea of “controlling” molecular packing in glasses is reasonably met with skepticism.  However\, as glasses are non-equilibrium materials\, a vast array of amorphous structures are possible in principle. Physical vapor deposition (PVD) produces glasses with properties that cannot be achieved by other preparation routes\, including high stability and controlled anisotropy. The exotic properties of PVD glasses can be explained by a surface equilibration mechanism: mobility near the free surface allows substantial equilibration during deposition\, even well below the conventional Tg. Initial work with organic glasses has now been extended to show aspects of ultrastability in metallic and chalcogenide glasses. \nThe active layers in commercial OLEDs are PVD glasses of organic semiconductors. Ultrastable glasses of organic semiconductors make longer-lasting OLEDs and in-plane orientation of emitter molecules produces more efficient OLEDs.  Co-deposition of two organic semiconductors often produces a homogeneous ultrastable glass but\, in other systems\, component separation occurs in the plane of the sample\, on a controllable length scale.

SUMMARY:MEAM Seminar: "Robots that Evolve on Demand"
DESCRIPTION:Soft robots have the potential to adapt their morphologies and behavioral control policies to changing tasks and environments. Inspired by the dynamic plasticity of living organisms and the general adaptability of animals\, this talk will discuss several shape-shifting soft robot platforms for multi-task performance and multi-environment locomotion—for example\, robotic skins\, robotic fabrics\, and robots with morphing limbs. The talk will also explore the active material components\, such as stretchable electronics and computation\, soft actuation\, and variable stiffness materials\, that enable predictable robot morphology changes. By harnessing these engineered materials and mechanisms\, we aim to unlock a wide range of capabilities for increasingly adaptive\, evolving robots.

SUMMARY:CIS Seminar: "Decentralized Mechanism Design: Cryptography Meets Game Theory"
DESCRIPTION:In classical auction design\, we take it for granted that the auctioneer is trusted and always implements the auction’s rules honestly. This assumption\, however\, no longer holds in modern auctions based on blockchains\, or those mediated by third-party platforms such as Google. For example\, in blockchain-based auctions\, the consensus nodes that partly act as the auctioneer are incentivized to deviate from honest behavior if profitable. Third-party auction platforms such as Google have also been involved in high-profile anti-trust lawsuits for manipulating their auctions.\n\n\n\n\nIn this talk\, I will describe our recent work on decentralized mechanism design\, where we aim to build a new scientific foundation for emerging auctions that are not backed by a trusted auctioneer. I will characterize the mathematical landscape of decentralized mechanism design\, by showing several infeasibility and feasibility results. I will also highlight how cryptography can play an essential role for bypassing impossibility results in decentralized mechanism design\, leading to a new class of auctions that not only incentivize bidders to act honestly\, but also incentivize the auctioneer to play by the book.

SUMMARY:ASSET Seminar: "Efficient Sharing of AI Infrastructures with Specialized Serverless Computing"
DESCRIPTION:Abstract: \nThe efficient sharing of AI infrastructures is becoming increasingly important in both public and private data centers. This demand is driven by two key factors: the proliferation of specialized AI models tailored for different users and applications\, and the highly dynamic nature of requests\, which are often on-demand. Dedicated GPU allocation in such scenarios results in prohibitively high costs and inefficient resource utilization. \nIn this talk\, I will introduce serverless computing as a promising paradigm for addressing these challenges by enabling efficient\, on-demand sharing of AI infrastructures. I will highlight its use cases and discuss key barriers to broader adoption. Following this\, I will present ServerlessLLM\, a state-of-the-art system designed to tackle key challenges in serverless large language model (LLM) inference\, particularly cold-start latency. Specifically\, I will cover ServerlessLLM’s novel contributions\, including its checkpoint format design\, locality-aware scheduling\, and inference request live migration. Finally\, I will outline open challenges beyond efficiency\, such as fairness\, privacy\, and sustainability\, which are critical for the future of serverless AI systems. \nZoom Link (if unable to attend in-person): https://upenn.zoom.us/j/95090162762

SUMMARY:Spring 2025 GRASP SFI: Guandao Yang\, Stanford University\, “Toward Spatial Intelligence with Limited Data”
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nModern artificial intelligences (AIs) rely heavily on internet-scale data with unified representations. However\, such large-scale homogeneous data isn’t readily available for spatial computing applications involving 3D geometry\, hindering the development of spatial intelligence— AIs that can generate and understand 3D spatial data. In this talk\, I will present ideas toward building spatial intelligence systems with limited 3D data. I will discuss my work combining existing mathematical models in graphics with foundation models in machine learning to generate and analyze 3D shapes. Finally\, I will conclude with a discussion about the future opportunities and challenges in developing data-efficient AIs for spatial computing and beyond.

SUMMARY:CBE Seminar: "Engineering Technologies for Enhanced Modeling\, Detection\, and Treatment of Neurological Disease" (Alice Stanton\, MIT)
DESCRIPTION:Abstract: \nNeurological conditions are the leading cause of illness worldwide\, though over 92% of clinically tested CNS drug candidates fail to become treatments. Contributing to this high failure rate is a lack of understanding of human disease mechanisms\, technologies to address them\, and the restrictive blood-brain barrier (BBB)\, which most compounds fail to cross. New models are critically needed that more faithfully recapitulate human neurological disease\, providing a tool for enhanced discovery of biomarkers and targets\, effective therapeutic development\, and personalized drug screening. In this seminar\, I will present my work in (1) developing biomaterials-based platforms to mimic physiological conditions\, probe fundamental questions\, and utilize as cell-carrying scaffolds\, (2) establishing a multicellular human cell-based model of the brain\, miBrain\, that incorporates neuronal\, glial\, vascular\, and immune components into 3D brain tissue with structural organization\, combining the power of induced pluripotent stem cell (iPSC) technology and tissue engineering\, and (3) utilizing the multicellular brain model to interrogate disease pathogenesis and delivery across the BBB\, harnessing a microfluidic platform I developed to enable 3D vascular perfusion within the miBrain. In my doctoral work\, I developed biomaterials-based platforms to probe fundamental questions of stem cell mechanotransduction and to utilize as cell-carrying scaffolds in tissue engineering approaches. In my postdoctoral work\, I applied these engineering tools to develop an advanced preclinical brain model\, extensively characterized and validated the platform\, and leveraged this system to model disease and BBB transport. I differentiate iPSCs into each of the six major brain cell types and assemble them in the Neuromatrix Hydrogel I developed to incorporate brain-niche cues and support cell network co-formation\, and culture them in high throughput well format or perfusable chip format. miBrains form integrated 3D immune-glial-neurovascular units with enhanced cell- and tissue-scale phenotypes inclusive of myelinated neuronal networks\, microglial immune cells\, and BBB. To enable perfusable vasculature within the miBrain\, I developed a novel microfluidic platform\, the GelChip\, via a 3D printing fabrication strategy\, that supports 3D network formation within complex co-cultures and engineered hydrogels to form the miBrain-on-Chip. Harnessing iPSCs from patient lines and genome editing to isolate the functional consequences of specific mutations\, I can form multicellular brain models across patient cohorts\, assess disease susceptibility\, probe mechanisms\, and screen putative interventions. I have harnessed the miBrain to model APOE4 risk for Alzheimer’s Disease\, recapitulating canonical disease hallmarks of increased reactive astrocytes\, amyloid aggregates\, and neuronal tau phosphorylation. Further\, I found that APOE4 astrocytes are sufficient to increase neuronal tau phosphorylation via crosstalk with microglia. I have thus established a novel preclinical brain model with broad utility for dissecting disease mechanisms\, assessing delivery to the brain\, and probing barrier function and other hallmarks in contexts of disease. In the conclusion of this seminar\, I will explore how multicellular human cell-based brain models and their underlying technologies and approaches can be leveraged to accelerate mechanistic understanding\, therapeutic target identification\, and drug candidate optimization for treatment delivery and efficacy.

SUMMARY:MSE Seminar: "Tuning Nanostructured Materials for Combustion Applications" (Kerri-lee A. Chintersingh\, Ph.D.\,  New Jersey Institute of Technology)
DESCRIPTION:Metals powders like aluminum and boron are attractive potential fuel additives for pyrotechnics\, propellants and explosives due to their high energy release upon oxidation. However\, they tend to agglomerate\, have lengthy ignition delays\, and low combustion rates/efficiencies. This work aims to design metal powders with tuned surface\, micro-structure\, morphology\, or chemistries to mitigate these challenges and favor the formation of desired products and high energy release; without jeopardizing thermochemical performance\, safety\, and stability. One approach used is to incorporate elements (like Fe) that can act as oxygen shuttle catalysts for surface reactions or to introduce elements to form exothermic intermetallic products (like Zr). Ball-milling allows a simple one pot technique to incorporate these elements to form metastable nanocomposite powders with lower ignition thresholds and improved combustion efficiencies. Novel experimental and diagnostic tools like x-ray phase contrast imaging (XPCI) and snapshot hyper-spectral imager for emissions and reactions (SHEAR) have been coupled to capture condensed phase/internal particle features and external optical emissions\, temperatures\, and gas phase species from combustion reactions\, respectively. Machine learning is also used to obtain quantitative data: identify trends\, detect anomalies\, and classify particle events from the videos produced from combustion scenes. Results show that surface modification to boron reduces ignition delays and doping boron with as low as 1wt% Fe improves surface reaction rates in air. Other additives like Bi and Co also help to change boron’s oxidation mechanism. For aluminum\, powders can be modified by emulsion assisted milling to produce spheres of various sizes by changing the milling parameter space with process control agents like acetonitrile and hexane\, and the addition of Zr can accelerate combustion in thermite formulations and allow Al powders to burn in multiple phases with improved combustion efficiencies.

SUMMARY:Spring 2025 GRASP Seminar: Nat Trask\, University of Pennsylvania\, "Geometric structure preservation in probabilistic digital twins"
DESCRIPTION:This will be a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. \nABSTRACT\nMotivated by the ever-increasing success of machine learning in language and vision models\, many aim to build AI-driven tools for scientific simulation and discovery. Contemporary techniques drastically lag behind their comparatively mature counterparts in modeling and simulation however\, lacking rigorous notions of convergence\, physical realizability\, uncertainty quantification\, and verification+validation that underpin prediction in high-consequence engineering settings. One reason for this is the use of “off-the-shelf” ML architectures designed for language/vision without specialization to scientific computing tasks. In this work\, we establish connections between graph neural networks and the finite element exterior calculus (FEEC). FEEC forms the backbone of modern mixed finite element methods\, tying the discrete topology of geometric descriptions of space (cells\, faces\, edges\, nodes and their connectivity) to the algebraic structure of conservations laws (the div/grad/curl theorems of vector calculus). By building a differentiable learning architecture mirroring the construction of Whitney forms\, we obtain a de Rham complex supporting FEEC\, allowing us to learn models combining the robustness of traditional FEM with the drastic speedups and data assimilation capabilities of ML. We then introduce a novel UQ framework based on optimal recovery in reproducing Hilbert spaces\, allowing the model to quantify epistemic uncertainty\, providing practical notions of trust where the model may be reliably employed.

SUMMARY:MEAM Seminar: “Digital Twins for the Earth System”
DESCRIPTION:Reliable forecasts of the Earth system are crucial for human progress and safety from natural disasters. Artificial intelligence offers substantial potential to improve prediction accuracy and computational efficiency in this field\, however this remains underexplored in many domains. Here we introduce Aurora\, a large-scale foundation model for the Earth system trained on over a million hours of diverse data. Aurora outperforms operational forecasts for air quality\, ocean waves\, tropical cyclone tracks\, and high-resolution weather forecasting at orders of magnitude loss computational cost than dedicated existing systems. With the ability to fine-tune Aurora to diverse application domains at only modest computational cost\, Aurora represents significant progress in making actionable Earth system predictions accessible to anyone.

SUMMARY:CBE Doctoral Dissertation Defense: "A molecular understanding of the structure-property relationships of model end-linked polymer networks" (Han Zhang)
DESCRIPTION:Abstract: \nPolymer networks\, including thermoplastics\, thermosets\, elastomers and gels\, are among the most versatile and widely utilized polymeric materials\, with applications spanning drug delivery systems\, membranes and implantable devices. A comprehensive understanding of the intricate relationship between the macroscopic properties and the structure and topology of polymer networks is crucial for advancing their utilization and facilitating the design of new materials. Molecular simulations have proven invaluable in exploring the structure-property relationships across various material systems. However\, compared to other polymeric systems\, such as polymer melts and glasses\, polymer networks have received comparatively less attention in molecular simulation studies. A primary challenge lies in the inherent inhomogeneities of polymer networks\, such as loop defects and dangling ends. Nevertheless\, many fundamental theories about polymer networks are based on idealized network models assuming homogeneous and defect-free structures. The understanding of polymer networks from a molecular perspective has remained limited\, as methods for construct models that accurately reflect real polymer network topologies have only recently begun to emerge. \nThis dissertation presents a computational framework that integrates molecular dynamics simulations\, Monte Carlo simulations and network analysis to explore the structure-property relationships in model end-linked polymer networks containing topological defects. We demonstrate that constructing networks from engineered tapered copolymers significantly expands the composition range in which co-continuous morphologies form. These co-continuous morphologies exhibit great potential to combine typically incompatible material properties within a single sample\, unlocking exciting opportunities for advanced materials design. Additionally\, we investigate the elastic properties of these networks\, providing valuable physical insights into how these properties are influenced by the key structural parameters of the networks\, including polymer mole fractions\, chain lengths and solvent quality. \nAdvanced computational tools are also employed to investigate the fracture process of end-linked polymer networks from a molecular perspective. Network analysis proves to be a simple yet powerful approach for identifying potential failure locations within polymer networks based solely on their initial undeformed configurations. Furthermore\, by leveraging molecular simulations\, we deliver a quantitatively refined\, molecular-level understanding of the fracture process\, tracking energy storage and dissipation at the bond\, chain\, generation and tree levels within the networks. These findings offer a molecular-level perspective on the influence of structure parameters and topological defects in the networks\, providing valuable insights for the mechanism behind the failure process and the inverse design strategies of network materials with tailored properties. \nMeeting ID: 966 7815 7284\nPasscode: 809660

SUMMARY:CIS Seminar: "Thinking Outside the GPU: Systems for Scalable Machine Learning Pipelines"
DESCRIPTION:Scalable and efficient machine learning (ML) systems have been instrumental in fueling recent advancements in ML capabilities. However\, further scaling these systems requires more than simply increasing the number and performance of accelerators. This is because modern ML deployments rely on complex pipelines composed of many diverse and interconnected systems.  \nIn this talk\, I will emphasize the importance of building scalable systems across the entire ML pipeline. In particular\, I will explore how large-scale ML training pipelines\, including those deployed at Meta\, require distributed data storage and ingestion systems to manage massive training datasets. Optimizing these data systems is essential as data demands continue to grow. To achieve this\, I will demonstrate how synergistic optimizations across the training data pipeline can unlock performance and efficiency gains beyond what isolated system optimizations can achieve. While these synergistic optimizations are critical\, deploying them requires navigating a large system design space. To address this challenge\, I will next introduce cedar\, a framework that automates the optimization and orchestration of ML data processing for diverse training workloads. Finally\, I will discuss further opportunities in advancing the scalability\, security\, and capabilities of the hardware and software systems that continue to drive increasingly sophisticated ML training and inference pipelines.

SUMMARY:ASSET Seminar: "Steering Machine Learning Ecosystems of Interacting Agents"
DESCRIPTION:Abstract:  \nModern machine learning models—such as LLMs and recommender systems—interact with humans\, companies\, and other models in a broader ecosystem. However\, these multi-agent interactions often induce unintended ecosystem-level outcomes such as clickbait in classical content recommendation ecosystems\, and more recently\, safety violations and market concentration in nascent LLM ecosystems. \nIn this talk\, I discuss my research on characterizing and steering ecosystem-level outcomes. I take an economic and statistical perspective on ML ecosystems\, tracing outcomes back to the incentives of interacting agents and to the ML pipeline for training models. First\, in LLM ecosystems\, we show how analyzing a single model in isolation fails to capture ecosystem-level performance trends: for example\, training a model with more resources can counterintuitively hurt ecosystem-level performance. To help steer ecosystem-level outcomes\, we develop technical tools to assess how proposed policy interventions affect market entry\, safety compliance\, and user welfare. Then\, turning to content recommendation ecosystems\, we characterize a feedback loop between the recommender system and content creators\, which shapes the diversity and quality of the content supply. Finally\, I present a broader vision of ML ecosystems where multi-agent interactions are steered towards the desired algorithmic\, market\, and societal outcomes. \nZoom Link (if unable to attend in-person): https://upenn.zoom.us/j/95467348262

SUMMARY:Spring 2025 GRASP & CIS Seminar: Yossi Gandelsman\, University of California\, Berkeley\, “Interpreting the Inner Workings of Vision Models”
DESCRIPTION:This will be a hybrid event with in-person attendance in Towne 100 Heilmeier Hall and virtual attendance on Zoom. \nABSTRACT\nIn this talk\, I present an approach for interpreting the internal computation in deep vision models. I show that these interpretations can be used to detect model bugs and to improve the performance of pre-trained deep neural networks (e.g.\, reducing hallucinations from image captioners and detecting and removing spurious correlations in CLIP) without any additional training. Moreover\, the obtained understanding of deep representations can unlock new model capabilities (e.g.\, novel identity editing techniques in diffusion models and faithful image inversion in GANs). I demonstrate how to find common representations across different models (discriminative and generative) and how deep representations can be adapted at test-time to improve model generalization without any additional supervision. Finally\, I discuss future work on improving the presented interpretation techniques and their application to continual model correction and scientific discovery.

SUMMARY:CBE Seminar: "Toward Efficient and Synthesizable In-silico Molecular Design" (Wenhao Gao\, MIT)
DESCRIPTION:Abstract: \nThe discovery of functional molecules plays a fundamental role in advancing chemical science and engineering\, yet it remains a costly and time-intensive process. Recent advances in computational methods\, particularly in generative artificial intelligence\, have introduced a new approach—generative molecular design—which holds the promise of efficiently identifying molecules with desired properties. However\, despite significant progress\, their practical impact in real-world applications has been limited. In this talk\, I will present our efforts to address critical bottlenecks in generative molecular design\, namely synthetic accessibility and sample efficiency. I will present the development of benchmarks that capture real-world complexity and the development of chemistry-tailored solutions to enhance the practicality of generative algorithms. Taken together\, these advances aim to close the gap between computational innovation and practical feasibility\, paving the way for the accelerated\, AI-driven discovery of novel functional molecules.

SUMMARY:BE Seminar - "Engineering cell state-specific gene regulation with AI and synthetic biology" (Sebastián Castillo Hair\, University of Washington)
DESCRIPTION:Cells across tissues\, developmental stages\, and disease conditions adopt distinct intracellular states – epigenomic\, transcriptomic\, and proteomic profiles – to compartmentalize function in time and space. The ability to write DNA- and RNA-encoded programs that sense and interface with cellular states has transformative potential for biotechnology\, for example in designing gene therapies with cell type- and disease-specificity to minimize off-target effects. However\, limited understanding of how cellular processes respond to cellular states remains a major bottleneck. Machine learning (ML) models that learn the regulatory grammar of cell state regulation from large datasets offer a powerful tool to overcome these barriers. In this talk I will present advances in combining ML and high throughput experiments to study and engineer DNA and RNA sequences that recognize cell types\, tissues\, and developmental stages. First\, I will focus on enhancers – DNA sequences that regulate transcription with cell type-specificity. We trained ML models on databases of genomic accessibility – an imperfect proxy of enhancer activity that is available for hundreds of cell types and tissues – and used them to design enhancers targeted to multiple cell types. Experimentally\, these enhancers drove stronger and more specific gene expression than endogenous controls when tested on 10 human cell lines\, including from muscle\, liver\, breast\, and embryonal tissues\, and even in vivo in mouse retinas. In the second part\, I will focus on mRNA sequence engineering. We used ML predictors of translation to optimize performance of an mRNA-delivered gene editor\, and developed predictors of mRNA degradation in response to microRNAs—non-coding RNAs that are differentially expressed across cell types. Using these\, we designed mRNAs with programmable specificity across 10 cell lines. Finally\, I will focus on gene regulation during the dramatic cell state transitions that occur during development. By training ML predictors of chromatin accessibility and mRNA regulation during zebrafish embryogenesis and applying explainable AI methods\, we uncovered regulatory grammar driving differentiation and gene expression dynamics. Our work shows the potential of combining ML\, high throughput experiments\, and synthetic biology to decode and engineer cell state-responsive biological systems.

SUMMARY:Spring 2025 GRASP Seminar: Hersh Sanghvi\, University of Pennsylvania\, "Online Controller Adaptation with Meta-Learned Models"
DESCRIPTION:This will be a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. \nABSTRACT\nControl tuning and adaptation present a significant challenge to the usage of robots in diverse environments. It is often nontrivial to find a single set of control parameters by hand that work well across the broad array of environments and conditions that a robot might encounter. Automated adaptation approaches must utilize prior knowledge about the system while adapting to significant domain shifts to find new control parameters quickly. In this talk\, I will present our work to develop a general framework that deals with these challenges. I’ll discuss how we can train predictive models of controller performance that quickly adapt to online data and can be used as cost functions within efficient sampling-based optimization routines to find new control parameters online that maximize performance. I’ll also demonstrate how our framework can be used to adapt controllers for four diverse systems: a simulated race car\, a simulated quadrupedal robot\, and a simulated and physical quadrotor.

SUMMARY:MSE Thesis Defense: "Cryogenic Microscopies of Energy Storage Materials: Insights into Metal Anodes\, Solid-Electrolyte Interfaces\, and Mxenes"
DESCRIPTION:The growing global energy demand has driven the development of advanced batteries\, particularly lithium metal anodes and anode-free systems\, due to their potential for higher energy density at reduced costs. However\, characterizing the interfaces within these systems presents a critical challenge due to their susceptibility to decomposition during conventional atomic-resolution analysis. The emergence of Cryogenic Electron Microscopy (cryo-EM)\, recognized by the 2017 Nobel Prize in Chemistry\, has revolutionized structural characterization by enabling near-atomic resolution imaging at liquid nitrogen temperatures. Originally transforming biomolecule imaging\, this technique has now extended to materials science\, making it ideal for investigating degradation-prone battery components and other sensitive materials while significantly reducing beam-induced damage.\nIn this work\, we developed and implemented an integrated characterization approach combining multiple advanced techniques. Our methodology merges aberration-corrected (Scanning) Transmission Electron Microscopy ((S)TEM) with spectroscopic tools including\nEnergy-Dispersive X-ray Spectroscopy (EDS) and Electron Energy Loss Spectroscopy (EELS) for atomic-level structural and chemical analysis. For sample preparation and protection\, we pioneered a novel approach combining Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) with cryogenic Focused Ion Beam (cryo-FIB)\, enabling robust detection and mapping of degradation-prone materials such as lithium hydride in battery anodes. Our systematic investigation revealed crucial insights into battery interfaces and materials. Using an integration of cryo-FIB-SEM\, cryo-(S)TEM\, EDS\, and 4D-STEM\, we uncovered the unique characteristics of solid-electrolyte interfaces (SEI) in sodium metal batteries with solid polymer electrolytes. The analysis revealed a distinctive thin SEI layer with reduced carbon content\, resulting in favorable “round” sodium nucleation patterns that contrast with the dendritic formations typical in liquid electrolyte systems. We extended this approach to examine electron beam-induced defects in titanium carbides and carbonitrides MXenes\, where our observations led to implementing cryo-STEM as a solution for preserving the pristine material structure and exam it as a potential current collector for the batteries.\nThis comprehensive study demonstrates the transformative potential of cryogenic electron microscopy techniques in advancing our understanding of sensitive battery materials and interfaces\, thereby contributing to the development of next-generation energy storage solutions.

SUMMARY:MEAM Ph.D. Thesis Defense: "Bio-inspired Architected Materials/structures with Enhanced Failure Characteristics"
DESCRIPTION:Structural failure is a critically important design consideration in many engineering applications. Nature provides a number of interesting examples of lightweight structural features that exhibit outstanding failure characteristics. Recent progress in additive manufacturing has facilitated precise control over geometric features\, allowing for the implementation of bio-inspired structural designs on a layer-by-layer basis. In this thesis\, we will introduce the role of geometry in the failure characteristics of bio-inspired architected materials/structures together with a new bio-mimic manufacturing method designed for these bio-inspired architected materials/structures. We will first present the use of bamboo-inspired void patterns to geometrically improve the failure properties of structures made from brittle polymers under flexural bending. Then\, we will extend this study into a material system with tunable plasticity to study the effect of plasticity on the fracture behavior of different architected voids. Lastly\, we will showcase the concept of employing simulated “swarms” of bio-inspired agents\, such as those mimicking the behavior of bees and ants\, to create novel designs of architected materials/structures that exhibit enhanced fracture properties\, including improved energy dissipation to failure and damage tolerance under complex loading conditions.

SUMMARY:MEAM Seminar: "Flow Architectures\, From Capillary Networks to Blood Transport through Organs"
DESCRIPTION:Flow systems in nature\, whether animate or inanimate\, have evolved in time toward greater efficiency by adapting\, or ‘morphing’\, their configuration to decrease resistance to the currents flowing through them. Observations at various scales indicate that the distribution of flow\, i.e. the connection of a point (source/sink) to a volume (sink/source) or vice-versa\, is the most efficient when it happens through a dendritic architecture. Flow channels function in concert with the structures around them\, as a combination of long and fast flows along the channels\, with short and slow flows through the surrounding medium. The ability to predict flow patterns enables engineers to propose flow designs for heat\, mass\, and fluid flows. Our previous work theorized the deterministic nature of morphing and showed how to obtain efficient flow configurations for combined and sometimes competing objectives. \nIn this talk we will discuss the blood flow architecture of the liver\, the largest organ in the body. The superimposition of three different types of networks (hepatic artery and portal vein trees as inflows\, and hepatic vein tree as outflow) leads to a very complex hierarchical structure made of several millions to billions of blood vessels. Out of the complexity of the blood flow system\, invoking the principles mentioned above\, we can predict the main features of this flow system and represent the hepatic blood circulatory system as a deterministic combination of dendritic networks and porous systems made of rigid or elastic vessels. \nNext\, we will consider the design of capillary networks for the cooling of high-power electronic components and how\, incidentally\, we understood that our theoretical approaches could also predict hydrotropism\, the growth of plant roots towards areas with high moisture level. While the mechanisms are complex and involve several drivers\, we extracted a conceptual understanding of how a plant root system evolves in time to connect more and more water sources while morphing its entire vasculature at every growth step. The network volume grows with the network\, but the volume distribution throughout all the channels morphs to allow enough capillary pressure in each branch and minimum friction losses to pull the maximum flow rate out of the system.

SUMMARY:ESE Spring Seminar - "Machine Learning: Algorithmic and Economic Perspectives"
DESCRIPTION:Algorithms are increasingly integrated into various societal applications\, often directly interacting with people and communities. This highlights the importance of understanding the interplay between algorithmic decisions and economic incentives when designing machine learning algorithms. In this talk\, I will explore two examples of this dynamic through the lens of privacy in data markets and fairness in dynamic resource allocation. \nThe first part of the talk investigates a data marketplace involving users\, platforms\, and data buyers. Users benefit from platform services in exchange for data\, incurring privacy loss when their data\, albeit noisily\, is shared with the buyer. The user chooses platforms to share data with\, while platforms decide on data privacy levels and pricing before selling to the buyer. The buyer finally selects platforms to purchase data from. Using a multi-stage game-theoretic framework\, I demonstrate how platform competition and buyer valuation shape user participation\, platform viability\, and overall welfare. I also discuss privacy regulatory interventions that can enhance user utility in mixed markets of high- and low-cost platforms. \nThe second part of the talk focuses on designing fair resource allocation algorithms through multi-round auctions\, where an auctioneer sells indivisible goods to groups of buyers while adhering to group fairness constraints. I demonstrate that optimal mechanisms can be characterized using a dynamic programming approach and involve dynamic subsidization policies that balance revenue maximization with fairness guarantees. Additionally\, I develop efficient approximations for computing these mechanisms\, providing insights into the computational challenges of designing fair resource allocation algorithms.

SUMMARY:Energy Week: "Catalyzing Clean Energy Investments in the Private Sector: The Role of the Federal Government"
DESCRIPTION:In this panel\, senior members of the Biden-Harris Administration will discuss the work they did to catalyze the private sector to commercialize critical technologies for the clean energy transition. Through the Bipartisan Infrastructure Law and the Inflation Reduction Act\, the U.S. Department of Energy (DOE) created over 900\,000 new jobs\, catalyzed over 900 new and expanded manufacturing facilities and for every dollar invested by the DOE\, six dollars was brought to the table by the private sector.  Learn more from key leaders on how this was accomplished. \nThe panel discussion will be moderated by Vanessa Chan\, the inaugural Vice Dean of Innovation & Entrepreneurship at Penn Engineering and the former Chief Commercialization Officer at DOE under President Biden. \nFeatured panelists: \n\nMaria Robinson\, former Director of the Grid Deployment Office (GDO)\nJigar Shah\, former Director of the Loan Programs Office (LPO)\nGiulia Siccardo\, former Director of the Office Manufacturing Energy & Supply Chain (MESC)\n\nThe event will be followed with light refreshments.
