SUMMARY:CBE Seminar: "Machine-learning-assisted Atomistic Modeling and Design of Complex Ionic Conductors for Next-Generation Energy Storage" (KyuJung Jun\, MIT)
DESCRIPTION:Abstract: \nFast solid-state Li-ion conductors are a crucial class of materials with the potential to enable all-solid-state batteries\, offering enhanced safety and energy density. However\, these materials remain rare\, and progress in developing novel solid electrolytes has been hindered by a lack of clear descriptors for superionic conductivity and a limited understanding of ion transport mechanisms across diverse conductors\, from inorganic crystals to polymers. Building on recent advances in computing power\,machine-learning algorithms\, material representations\, and analysis tools\, my research directly addresses these challenges\, guiding experimental efforts to discover new superionic conductors. In this talk\, I will present three of my representative efforts in this direction. First\, I will discuss how identifying structural features of superionic conductors enabled high-throughput screening\, leading to the discovery of over 20 novel inorganic superionic conductors. Second\, I will share how my research has resolved a long-standing debate on the lithium transport mechanism—known as the ‘paddlewheel effect’ in plastic crystal phases—by providing temporally and spatially resolved correlation insights. Third\, I will introduce new algorithms that I have developed to decompose Onsager transport coefficients\, allowing us to identify and quantify the contributions of various transport mechanisms in lithium polymer electrolytes\, with potential applications to inform mechanistic understanding in any complex ion-conducting medium. Bringing these efforts together\, I will discuss how these correlation analysis tools\, machine learning interatomic potentials\, and generative models represent a breakthrough in achieving both high accuracy and computational efficiency\, opening up unprecedented opportunities to model and understand complex dynamic phenomena that were previously inaccessible with traditional ab initio calculations or classical models.

SUMMARY:CBE Seminar: "Prioritization of Research\, Development\, and Deployment Pathways for a Circular Bioeconomy" (Jeremy Guest\, UIUC)
DESCRIPTION:Abstract: \n\nSocieties have prospered using a linear “take-make-use-dispose” approach\, extracting natural resources to make products\, using them\, and ultimately discarding them or their residues. This unsustainable approach has exploited natural resources at a rate that has caused excessive pollution and loss of biodiversity\, and is leading to a global climate crisis. In response to this challenge\, industries are seeking technological solutions that will meet societal needs in a way that is financially viable while supporting the pursuit of broader goals for sustainability (e.g.\, resource circularity\, carbon neutrality\, equity). This transition has become a catalyst for research and development\, but a critical challenge to achieving rapid and transformative innovations has been the expansive landscape of technology development pathways and the lack of a transparent and consistent framework to target investment. \nThis presentation will focus on the prioritization of research\, development\, and deployment (RD&D) pathways for the conversion of renewable resources into biofuels and bio-based products. Using a structured methodology – Quantitative Sustainable Design (QSD) – we integrate process design\, simulation\, techno-economic analysis (TEA)\, and life cycle assessment (LCA) under uncertainty to elucidate drivers of system sustainability\, identify performance gaps\, evaluate tradeoffs and optimize across alternatives\, and assess context-specific implications of technology advancement and deployment. Leveraging examples from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI)\, we will focus on the conversion of perennial grasses (Miscanthus\, switchgrass\, sugarcane) and agricultural residues to biofuels (sustainable aviation fuel [SAF]) and bioproducts (e.g.\, 3-hydroxypropionic acid [3-HP]\, triacetic acid lactone [TAL])\, including the exploration of opportunities for the integration of decarbonized processes with existing infrastructure (e.g.\, co-processing of SAF). In addition to demonstrating specific potential pathways to advance the circular bioeconomy\, this presentation will make the process of QSD more accessible to researchers and technology developers across disciplines\, including for the broader prioritization of RD&D for novel technologies.

SUMMARY:Spring 2025 GRASP SFI: Harshil Parekh\, BotBuilt\, “From GRASP to BotBuilt: Using Robotics and AI to Revolutionize Construction”
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nConstruction remains one of the least automated industries\, struggling with labor shortages\, inefficiencies\, and rising costs. At BotBuilt\, we are revolutionizing the way homes are built by leveraging robotics and AI to automate framing\, making construction faster\, safer\, and easier. \nIn this talk\, I will discuss the key challenges we are solving at BotBuilt\, from automating complex construction tasks to integrating robotics seamlessly into existing workflows. I will then share how my experiences at the GRASP Lab have equipped me to tackle these problems. By bridging research with real-world applications\, I’ll highlight how the skills I developed at Penn directly contribute to advancing robotics and AI in construction.

SUMMARY:CIS Seminar: " Specializing LLMs for Reliability"
DESCRIPTION:Large language models (LLMs) have advanced the frontiers of AI reasoning: they can synthesize information from multiple sources\, derive new conclusions\, and explain those conclusions to their users. However\, LLMs do not do this reliably. They hallucinate facts\, convincingly state incorrect deductions\, and exhibit logical fallacies like confirmation bias. In this talk\, I will describe my lab’s work on making LLM systems reliable by introspecting their behavior. First\, I will demonstrate that better understanding of LLMs helps us train them to be more reliable reasoners. Our work shows that model interpretation techniques can advance training methodology and dataset curation for reasoning models. Second\, I will argue that automating fine-grained evaluation of LLM output provides a level of understanding necessary for further progress. I will describe the ingredients of effective automated evaluators and a state-of-the-art factuality evaluation system\, MiniCheck\, showing that analyzing the nature of hallucinations can help reduce them. Finally\, I will describe how deeper understanding of LLMs will let us tackle their most fundamental limitations\, such as their inconsistency when given different inputs. I will propose how these pieces might soon be combined to form reliable AI systems.

SUMMARY:Spring 2025 GRASP Seminar: Erdem Bıyık\, University of Southern California\, “Robot Learning with Minimal Human Feedback”
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nThe lack of large robotics datasets is arguably the most important obstacle in front of robot learning. While large pretrained models and algorithms like reinforcement learning from human feedback led to breakthroughs in other domains like language and vision\, robotics has not experienced such a significant influence due to the excessive cost of collecting large datasets. In this talk\, I will discuss techniques that enable us to train robots from very little human feedback\, as little as one demonstration or one language instruction\, or their natural eye gaze. I will dive into reinforcement learning from human feedback\, and propose an alternative type of human feedback based on language corrections to improve data-efficiency. I will finalize my talk by presenting how existing large pretrained vision-language models can be used to generate direct supervision for robot learning.

SUMMARY:ESE Guest Seminar - "On Team Decision Problems with Nonclassical Information Structures"
DESCRIPTION:Team theory is a mathematical formalism for decentralized stochastic control problems in which a “team\,” consisting of a number of members\, cooperates to achieve a common objective. It was developed to provide a rigorous mathematical framework of cooperating members in which all members have the same objective yet different information. In static team problems\, the information received by the team members is not affected by the decisions of other team members\, while in dynamic team problems\, the information of at least one team member is affected by the decisions of other team members. If there is a prescribed order in which team members make decisions\, then such a problem is called a sequential team problem. The information structures in sequential team decision problems designate who knows what about the status of the team and are classified as classical\, partially nested\, and non-classical. In classical information structures\, all team members receive the same information and have perfect recall. In partially nested information structures\, some team members have a nonempty intersection of their information structures while they have perfect recall. Any information structure that is not classical or partially nested is called nonclassical. In this talk\, I consider sequential dynamic team decision problems with nonclassical information structures. First\, I will address the problem from the point of view of a “manager” who seeks to derive the optimal strategy for the team in a centralized process. I provide structural results that yield an information state for the team\, which does not depend on the control strategy\, and thus\, it can lead to a dynamic programming decomposition where the optimization problem is over the space of the team’s decisions. I will then provide structural results for each team member that yield an information state that does not depend on their control strategy\, and thus\, it can lead to a dynamic programming decomposition where the optimization problem for each team member is over the space of their decisions. Finally\, I will show that the solution of each team member is the same as the one derived by the manager. Therefore\, each team member can derive their optimal strategy\, which is also optimal for the team\, without the manager’s intervention.

SUMMARY:ESE Spring Seminar - "Towards quantum interconnects: entangling microwave and optical photonic qubits"
DESCRIPTION:Modern computing and communication technologies\, such as supercomputers and the internet\, are based on optically-linked networks of information processors operating at microwave frequencies. An analogous architecture has been proposed for quantum networks using optical photons to distribute entanglement between remote superconducting quantum processors. Here I will discuss our recent demonstration of a chip-scale source of entangled optical and microwave photonic qubits – an essential milestone towards realizing such an architecture. Our device platform integrates a piezo-optomechanical transducer with a superconducting resonator that is robust under optical illumination. We drive a photon-pair generation process and employ a dual-rail encoding to prepare entangled states of microwave and optical photons. This entanglement source can directly interface telecom wavelength time-bin qubits and GHz frequency superconducting qubits; two well-established platforms for quantum communication and computation\, respectively.

SUMMARY:Spring 2025 GRASP Seminar: Shenlong Wang\, University of Illinois Urbana-Champaign\, "Interactive Images\, Videos\, and Worlds"
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 512 and virtual attendance on Zoom. \nABSTRACT\nOur group’s goal is to build a world simulator from visual observations that can answer “what-if” questions. In pursuit of this goal\, we develop various methods for modeling the world from images and harnessing physical simulation and generative models to create immersive new experiences. In today’s talk\, we will focus on creating realistic and immersive experiences that allow users and agents to interact with images\, videos\, and 3D worlds captured from the real world. We will cover applications in content creation\, autonomy\, and agriculture. Finally\, I will provide a brief personal outlook on open research topics that make all images and videos interactive.

SUMMARY:MEAM Seminar: "Neural Operator for Scientific Computing"
DESCRIPTION:Accurate simulations of physical phenomena governed by partial differential equations (PDEs) are foundational to scientific computing. While traditional numerical methods have proven effective\, they remain computationally intensive\, particularly for complex\, large-scale systems. This talk introduces the neural operator\, a machine learning framework that approximates solution operators in infinite-dimensional spaces\, enabling efficient and scalable PDE simulations across varying resolutions and scales. Beginning with the Fourier Neural Operator (FNO) architecture\, we explore recent advances in self-supervised learning using scale-consistent learning techniques and modeling complex geometries using adaptive mesh methods. We demonstrate the framework’s practical impact through real-world applications in weather prediction\, carbon capture\, and plasma dynamics. The talk concludes by examining how foundational tools in computational mathematics can advance efficient architecture design\, highlighting the expanding intersection between machine learning\, computational science\, and engineering.

SUMMARY:Spring 2025 GRASP Seminar: Sarah Keren\, Technion - Israel Institute of Technology\, “Encouraging Autonomous Agents to Behave Nicely”
DESCRIPTION:This will be an in-person event only with attendance in Levine 307. This seminar will NOT be recorded. \nABSTRACT\nAutonomous AI agents are deployed in increasingly complex and uncertain environments where they must account for the presence of other agents while trying to achieve their own objectives. Moreover\, such agents may require assistance from other agents to efficiently accomplish their assigned task or even be able to complete it at all. \nThis work aims to develop theoretical foundations for agents to learn and adopt cooperative behaviors by introducing Value of Assistance (VOA) – a novel measure of the potential performance improvement achieved by assistive actions. The benefit of using VOA will be demonstrated in multi-robot navigation and collaborative manipulation settings. In addition\, adaptations of VOA to other stochastic and partially observable multi-agent settings will be discussed\, including our ongoing work on AI-enabled energy systems.

SUMMARY:MEAM Ph.D. Thesis Defense: "Leveraging Impedance-Related Properties for Free Self-Sensing in Actuators for Compact Robots"
DESCRIPTION:Robotic systems\, particularly at small scales\, require efficient actuation and sensing solutions that maintain compactness. We are interested in systems where sensing and actuation are seamlessly integrated\, specifically using impedance-related properties—such as electrical resistance\, induced electromotive force (emf)\, and inductance— for free self-sensing in actuators without additional sensors. We explore three main example applications: (1) Resistance-based sensing in I-cord knitted shape memory alloy (SMA) actuators enables real-time strain estimation\, allowing direct feedback for robotic motion\, (2) Induced emf sensing in custom linear solenoid actuators provides contact and velocity feedback\, demonstrated in applications such as bistable origami grippers and artificial facial muscle devices for facial reanimation surgery\, and (3) Inductance-based sensing further enables position and flow monitoring in active valve systems for bidirectional swimming of underwater swimmer robots\, offering a self-contained alternative to external instrumentation. This thesis presents the theoretical foundations\, experimental validation\, and real-world robotic demonstrations of these sensing approaches. By embedding sensing directly into actuators\, this work advances the development of compact and robust robotic systems with potential applications in origami-inspired soft robots\, bio-inspired robots\, and medical implant devices.

SUMMARY:PICS Colloquium: Unraveling Internal Friction in a Coarse-Grained Protein Model
DESCRIPTION:Understanding the dynamic behavior of complex biomolecules requires simplified models that not only make computations feasible but also reveal fundamental mechanisms. Coarse-graining (CG) achieves this by grouping atoms into beads\, whose stochastic dynamics can be derived using the Mori-Zwanzig formalism\, capturing both reversible and irreversible interactions. In liquid\, the dissipative bead-bead interactions have so far been restricted to hydrodynamic couplings. However\, friction does not only arises from the solvent but notably\, from the internal degrees of freedom missing in the CG beads. This leads to an additional “internal friction” whose relevance is studied in this contribution. By comparing with all-atom molecular dynamics (MD)\, we neatly show that in order to accurately reproduce the dynamics of a globular protein in water using a coarse-grained (CG) model\, not only a precise determination of elastic couplings and the Stokesian self-friction of each bead is required. Critically\, the inclusion of internal friction between beads is also necessary for a faithful representation of protein dynamics. We propose to optimize the parameters of the CG model through a self-averaging method that integrates the CG dynamics with an evolution equation for the CG parameters. This approach ensures that selected quantities\, such as the radial distribution function and the time correlation of bead velocities\, match the corresponding MD values.

SUMMARY:CIS Seminar: "Learning Theoretic Foundations for Modern (Data) Science"
DESCRIPTION:In this talk\, I will explain how fundamental problems in computational learning theory are at the heart of modern problems in machine learning and scientific applications and how algorithmic insights in mathematically tractable models can inspire new solutions in a wide variety of domains.\nI will explore two directions. First\, I will explore algorithmic foundations for model stealing of language models.  Model stealing\, where a learner tries to recover an unknown model through query access\, is a critical problem in machine learning. Here\, I will aim to build a theoretical foundation for designing model stealing algorithms.  Second\, I will introduce Hamiltonian learning\, a central computational task towards understanding and benchmarking quantum systems.  I will highlight how the lens of learning theory plays a key role in identifying and circumventing previous barriers and allows us to give efficient algorithms in settings that were previously conjectured to be intractable.

SUMMARY:IDEAS/STAT Optimization Seminar: "Theoretical foundations for multi-agent learning"
DESCRIPTION:As learning algorithms become increasingly capable of acting autonomously\, it is important to better understand the behavior that results from their interactions. For example\, a pervasive challenge in multi-agent learning settings\, which spans both theory and practice and dates back decades\, has been the failure of convergence for iterative algorithms such as gradient descent. Accordingly\, a longstanding central question with broad relevance is: how quickly can we compute solution concepts\, i.e.\, equilibria\, in multi-agent settings?\n\nI will discuss results which address this question at a variety of levels\, starting from foundational settings involving normal-form games and building up to complex problems such as multi-agent reinforcement learning which more aptly model realistic situations. First\, I will present a result establishing a near-optimal convergence rate for a simple online learning algorithm in normal-form games\, resolving a decade-long line of work which gave suboptimal bounds. I will then discuss a new algorithm for minimizing swap regret exponentially faster than previous approaches. Our algorithm allows us to answer several open questions\, such as by establishing the first PTAS for correlated equilibria in extensive-form games.\n\nBeyond contending with agents’ differing incentives\, the increasing use of machine learning algorithms presents other challenges\, such as the proliferation of AI-generated content. In the latter part of the talk\, I will discuss an approach to detect such content via watermarking. Our watermarking scheme is the first to embed a watermark in a language model’s output in a way which only leads to negligible changes in the distribution of the output but which is robust to adversarial edits.\n\nZoom link: https://upenn.zoom.us/j/98090439937 (Meeting ID: 980 9043 9937)

SUMMARY:ESE Spring Seminar - "Quantum Simulation of Electronic Materials with a Superconducting Qubit Array"
DESCRIPTION:Arrays of coupled superconducting qubits are a compelling platform for analog quantum simulations of solid-state matter and many-body physics. These devices natively emulate the Bose-Hubbard model while offering a high degree of control\, fast operation rates\, and site-resolved readout. We discuss recent experiments using a 4-by-4 array of transmon qubits. By adopting a parametric coupling scheme\, we emulate a 2D material in an adjustable electromagnetic field and demonstrate the Aharonov-Bohm effect\, Faraday’s law of induction\, and the Hall effect. We then emulate a material with flat bands\, and we study the interplay between band structure and disorder-induced localization and delocalization. We conclude by discussing a near-term path towards utility-scale analog quantum simulators based on superconducting qubit arrays.

SUMMARY:CBE & BE Seminar: "Targeting the Brain and Behavior to Probe the Dynamics of Aging" (Claire Bedbrook\, Stanford University)
DESCRIPTION:Bio & Abstract: \nClaire Bedbrook is an engineer and neuroscientist working to extend lifespan by modulating the brain. Claire was trained in chemical engineering at the University of California\, Berkeley. She completed her Ph.D. in Bioengineering at the California Institute of Technology with Professor Frances Arnold and Professor Viviana Gradinaru\, where she engineered molecular tools for controlling and recording the brain using machine-learning-based protein engineering. Claire is now a Helen Hay Whitney Fellow and Wu Tsai Neurosciences Institute Interdisciplinary Postdoctoral Scholar in the labs of Professor Karl Deisseroth and Professor Anne Brunet at Stanford University\, where she is pioneering approaches to understand and engineer the process of aging. Studying intact systems longitudinally over life in high dimensions is a fundamental unmet need in biology. If achieved\, this would uncover key principles of aging\, the leading driver of most chronic diseases. However\, given the long timescale of vertebrate aging\, recording this continuous\, lifelong transformation is highly challenging. Claire’s research seeks to overcome this challenge by leveraging the African killifish\, a genetically tractable vertebrate model with a naturally compressed lifespan that recapitulates key aging features. Using the short-lived killifish\, she engineered a platform to track every moment of a vertebrate animal’s life\, capturing multidimensional behavioral dynamics across timescales from milliseconds to entire lifespans. This system offers an unprecedented\, unbiased view into the progression of aging.

SUMMARY:Spring 2025 GRASP SFI: Qinghua Liu\, Microsoft Research\, “When Is Partially Observable Reinforcement Learning Not Scary?”
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nPartial observability is ubiquitous in Reinforcement Learning (RL) applications\, where agents must make sequential decisions despite lacking complete information about the latent states of the controlled system. Partially observable RL is notoriously challenging in theory—well-known information-theoretic results show that learning partially observable Markov decision processes (POMDPs) requires an exponential number of samples in the worst case. However\, this does not rule out the existence of interesting subclasses of POMDPs that encompass a diverse set of practical applications while remaining tractable. \nIn this talk\, we identify a rich family of tractable POMDPs\, which we call weakly revealing POMDPs. This family excludes pathological cases where observations provide so little information that learning becomes infeasible. We prove that for weakly revealing POMDPs\, a simple algorithm combining optimism and Maximum Likelihood Estimation (MLE) is sufficient to guarantee polynomial sample complexity. Finally\, we discuss the practical implications of this theory\, including strategies for collecting samples in partially observable tasks and the limitations of purely model-free algorithms.

SUMMARY:ASSET Seminar: "Demystifying the Inner Workings of Language Models"
DESCRIPTION:Abstract: \nLarge language models (LLMs) power a rapidly-growing and increasingly impactful suite of AI technologies. However\, due to their scale and complexity\, we lack a fundamental scientific understanding of much of LLMs’ behavior\, even when they are open source. The “black-box” nature of LMs not only complicates model debugging and evaluation\, but also limits trust and usability. In this talk\, I will describe how my research on interpretability (i.e.\, understanding models’ inner workings) has answered key scientific questions about how models operate. I will then demonstrate how deeper insights into LLMs’ behavior enable both 1) targeted performance improvements and 2) the production of transparent\, trustworthy explanations for human users. \nZoom Link (if unable to attend in-person): https://upenn.zoom.us/j/99113576305

SUMMARY:MEAM Seminar: "Real-Time Safe and Energy-Efficient UAV Motion Planning in Windy Urban Environments"
DESCRIPTION:Recent advancements in hardware and software are bringing autonomous aerial vehicles closer than ever to finally delivering on futuristic visions of flying cars and package delivery drones. However\, the safe deployment of autonomous aircraft at scale in urban environments poses significant challenges\, one of which being uncertainties contributed by complex spatial and temporal winds. Clusters of buildings generate dangerous high speed wind flow patterns which increase both the costs and risks for aerial operations. Existing approaches for modeling and planning for urban winds rely on either distributed sensors\, extensive exploration\, or accurate global representations of the environment and expensive offline calculations. \nIn this talk\, we first introduce a novel approach to predicting wind flow fields in real time\, without GPS or prior knowledge of the environment\, and only using on-board sensing with minimal compute requirements. We accomplish this by strategically reducing the problem to predicting the wind flow field on a local robot-centered domain\, and by leveraging the predictability of the wind flow field induced by conservation of mass and momentum constraints from nearby topography. Using vast amounts of simulated winds through procedurally-generated urban environments\, we train deep neural networks to synthesize navigational LiDAR scans with sparse in-situ measurements of the wind\, achieving real-time prediction rates and surprising generalizability. In the latter half of the talk\, we demonstrate how the local wind prediction can be incorporated into a receding horizon optimal control architecture to improve the accuracy of trajectory forecasting and cost functions associated with energy consumption. The result is a system that is capable of perceiving surrounding winds in real time using readily-available on-board sensors\, and then adjusting the planned route accordingly to avoid environmental hazards and maximize energy efficiency along the way.

SUMMARY:CIS Seminar: "Efficient Probabilistically Checkable Proofs from High-Dimensional Expanders"
DESCRIPTION:The PCP theorem\, proved in the 90’s\, shows how to encode a proof for any theorem into a format where the theorem’s correctness can be verified by making only a constant number of queries to the proof. This result is a significant milestone in computer science and has important implications for approximation algorithms\, cryptography\, and cloud computing.\nIn this talk\, I will cover some exciting progress on constructing efficient PCPs. My work gives a systematic way to construct PCPs\, improving upon the state-of-the-art PCP constructions from nearly 20 years ago. This implies that many well-known approximation algorithms are nearly-optimal under well-believed complexity-theoretic conjectures. In the process\, we also solve various conjectures in property testing and distributed computing. These advances are facilitated by the newly-emerging theory of high-dimensional expansion and draw upon connections with various areas of theoretical computer science and mathematics.

SUMMARY:ESE Spring Seminar - "AI as a Lens: Expanding Vision for Scientific Discovery"
DESCRIPTION:Conventional approaches to scientific discovery often prioritize building larger sensors\, gathering more data\, and scaling up computational power. In this talk\, I will present a complementary perspective: extracting insights hidden in the data we already have. The key lies in using AI not as a black-box predictor\, but as a tool for interpreting data through its underlying physical process. \nI will demonstrate how AI\, when integrated with the physics of light propagation\, can serve as a computational lens to overcome fundamental limitations in fields ranging from biomedicine to astrophysics. Specifically\, I will showcase two compelling applications: non-invasive imaging through scattering biological tissues\, and detecting faint exoplanets against the overwhelming brightness of their host stars. \nThese methods represent a departure from traditional learning-based approaches that rely on fitting models to training labels and hoping for generalization. Instead\, with physics-informed strategies that decode how light propagates\, we can transform raw measurements into scientifically meaningful insights—without requiring costly hardware upgrades or human-annotated datasets. Finally\, I will outline future directions for combining AI with physical principles\, enabling us to unlock more phenomena once considered hidden and accelerating discoveries in healthcare\, astronomy\, and beyond.

SUMMARY:MEAM Seminar: "Miniaturized Robots and Probes for Precision Health"
DESCRIPTION:Designing miniaturized robots and bioelectronic devices will enable access throughout the entire human body\, leading to novel procedures at the cellular level and offering localized diagnosis and treatment with unprecedented precision and efficiency. However\, the soft\, complex\, and multi-dimensional nature of biological systems poses significant challenges for mechanical design\, manufacturing\, materials engineering\, and functional integration in miniaturized devices. My research focuses on developing miniaturized robots and probes that seamlessly interface with and precisely interact with biological systems. By leveraging precision 3D nanomanufacturing\, novel biomaterials\, and emerging biophysical principles\, we aim to engineer functional microrobots and bioelectronic devices to deepen physiological understanding\, enable predictive diagnostics\, and advance precision therapeutics. In this talk\, I will first provide an overview of the challenges and design rationales behind micro/nanorobotics and mechanically compliant bioelectronics\, followed by highlights of a few recent advances from my lab\, inspired by biological systems or driven by biomedical problems. These include 3D-printed microrobots capable of magnetic actuation\, imaging\, and magnetothermal hyperthermia; hyperelastic microrobots with extreme deformability for navigating complex physiological constraints; adaptive\, skin-conformal soft microelectrode arrays for high-fidelity electromyography recordings and robotic control; and microfabricated neural probe arrays for brain-wide neural circuit interrogation. These miniaturized robots and probes will enable unprecedented interactions across biological\, physical\, and virtual domains\, driving the next generation of precision healthcare.

SUMMARY:PICS Colloquium: Powering decarbonization with modeling and optimization of renewables in the multi-scale atmosphere
DESCRIPTION:To meet net-zero carbon emissions targets by mid-century\, up to a -fold increase in wind power capacity is required. Acceleration to this rate requires urgent improvements to efficiency and reliability of installed wind farms\, as well as cost reductions for future offshore farms. To expand energy production\, wind turbines are rapidly increasing in size\, wind farms are proliferating to new locations and are increasing in size and siting density\, and novel wind farm design and control methods are increasingly deployed. But current engineering models driving wind power design and control rely on idealized theory that neglects key aspects of the rotor aerodynamics and the turbulent atmospheric boundary layer\, which are increasingly important for larger turbines and farms. We revisit the first-principles of mass\, momentum\, and energy conservation to develop a Unified Momentum theory for rotors across operating regimes\, accounting for arbitrary misalignments between rotor and inflow and thrust coefficients. The model is validated against large eddy simulations and generalizes and replaces both classical momentum theory and the Betz limit. Going from the scale of a turbine to a farm\, wake losses\ncan reduce farm energy by 30%\, a significant loss that negatively impacts economics and is increasing given wind power expansion. Using large eddy simulations of wind turbines operating in a range of atmospheric conditions\, we systematically uncover the significant roles of Coriolis effects and stability on wake recovery\, trajectory\, and morphology. A new fast-running wind farm model that accounts for the coupled rotor operational and atmospheric effects on wakes is developed. The wind farm model is\nleveraged for applications including collective control and for control co-design\, applied in both simulations and utility-scale field experiments. Collective control can increase the energy generation of wind farms through software modifications\, without additional turbines or hardware. Going from the scale of a wind farm to the energy system\, we leverage an integrated climate and energy system modeling framework to design minimum-cost decarbonized energy systems. Energy system optimization with high-resolution atmospheric predictions reveals opportunities for complementarity between spatiotemporal variations in wind and solar supply to align with energy demand and to lower the cost of decarbonized energy systems.

SUMMARY:IDEAS/STAT Optimization Seminar: "Foundations of Deep Learning: Optimization and Representation Learning"
DESCRIPTION:Deep learning’s success stems from the ability of neural networks to automatically discover meaningful representations from raw data. In this talk\, I will describe some recent insights into how optimization enables this learning process. First\, I will show how optimization algorithms exhibit surprisingly rich dynamics when training neural networks\, and how these complex dynamics are actually crucial to their success – enabling them to find solutions that generalize well\, navigate challenging loss landscapes\, and efficiently adapt to local curvature. I will then explore how optimization enables neural networks to adapt to low-dimensional structure in the data\, how the geometry of the loss landscape shapes the difficulty of feature learning\, and how these ideas extend to in-context learning in transformers. \n  \nZoom link: https://upenn.zoom.us/j/93151261686 (Meeting ID: 931 5126 1686)

DESCRIPTION:Abstract: \nTerrestrial plants harbor renewable carbon resources in their cell walls that can directly contribute to decarbonization of the transportation and materials sectors\, but the heterogeneous\, aromatic lignin polymer found in plants has long obstructed both natural- and humankind-driven endeavors to deconstruct plant biomass to valuable products. However\, viable methods to valorize lignin are essential to ultimately enable second-generation biorefining\, given that lignin can comprise up to 40% of the carbon in lignocellulose\, but today it is merely burned for low-value heat and power. To this end\, this talk will cover our efforts (with many collaborators) to separate the lignin polymer from the plant cell wall and use both chemical and biological catalysis to convert it into molecules and polymers that are either drop-in replacements for products sourced from fossil carbon today or that exhibit performance-advantaged properties relative to petrochemical incumbents. Specifically\, we are focused on catalytic oxidation to depolymerize lignin into bio-available intermediates coupled to metabolic engineering approaches that convert mixtures of aromatic compounds to single products\, which can find use in performance-advantaged biopolymers. In parallel\, we are also developing and scaling methods to remove lignin from the cell wall through reductive catalysis and to selectively conduct hydrodeoxygenation to produce sustainable aviation fuel blendstocks.
