SUMMARY:ESE Fall Seminar - "Big AI for Small Devices"
DESCRIPTION:As artificial intelligence (AI) transforms industries\, state-of-the-art models have exploded in size and capability. However\, deploying these models on resource-constrained edge devices remains a significant challenge. Smartphones\, wearables\, and IoT sensors face stringent limitations on compute\, memory\, power\, and communication\, creating a gap between demanding AI models and edge hardware capabilities that hinders the deployment of intelligence. In this talk\, we will re-examine techniques to bridge this gap and embed big AI on small devices. We will begin by discussing how the properties of various hardware platforms impact the design strategies of efficient deep neural network (DNN) models\, such as quantization and pruning. Next\, we will discuss techniques aimed at reducing the inference and training costs of distributed collaborative edge AI systems. Finally\, we will delve into the underlying design philosophies and their evolution toward efficient\, scalable\, robust\, and secure edge computing systems.

SUMMARY:MEAM Seminar: "Natural Structural Materials: Lessons on Toughening Mechanisms\, Weight Reduction\, and Multifunctionality"
DESCRIPTION:Structural materials that are damage-tolerant\, lightweight\, multifunctional\, and sustainable are highly desirable for many engineering applications. Such combinations of properties are often found in the biological world. Organisms from nature construct various biological structural materials for protection\, predation\, body support\, camouflage\, etc. Despite the fact that these materials are made from limited constituent materials with usually poor intrinsic mechanical properties\, such as brittle minerals and soft biopolymers\, biological materials are often able to achieve remarkable mechanical properties while offering additional functionalities simultaneously\, such as low density\, coloration\, transparency\, flexibility\, visual sensitivity\, etc. In this talk\, I will present our recent work in elucidating the structure-property relationships in some natural structural materials by focusing on their strategies for achieving damage tolerance\, weight reduction\, and multifunctionality. For example\, I will present a unique damage-tolerant\, dual-scale\, single-crystalline\, low-density microlattice we recently discovered in an echinoderm skeletal system. Our research combines quantitative multiscale 3D structural analysis\, in-situ mechanical analysis\, theoretical and computational modeling\, and design and manufacturing of bio-inspired materials. I hope this talk will stimulate more discussions in research areas such as materials\, mechanics\, biomimetics\, biology\, and manufacturing.

SUMMARY:CIS Seminar: "Trustworthy Forecasting Algorithms"
DESCRIPTION:Algorithms are increasingly tasked with forecasting the probabilities of uncertain events: a creditor repaying a loan\, a user clicking an advertisement\, or a word appearing next in a stream of text\, for example. Such forecasts are trustworthy if their users can be sure they won’t regret treating the predicted probabilities as if they were actual distributions from which outcomes would be sampled. The term “calibration” refers to various measures of forecast accuracy that formalize this property of trustworthiness. Defining calibration\, and designing algorithms to achieve it\, turns out to be a tightrope walk between strong definitions\, which ensure reliable results for users but are computationally and statistically harder to achieve\, and weak definitions\, which have the opposite benefits and drawbacks. I will report on some recent research aimed at locating a sweet spot between these two extremes: calibration properties that are achievable using no more samples or computation than the easiest statistical learning tasks\, while providing guarantees for downstream users that are\, in many cases\, as powerful as the strongest notions of calibration. \nThis talk is based on joint work with Michael Kim\, Princewill Okoroafor\, Renato Paes Leme\, Jon Schneider\, and Yifeng Teng.

SUMMARY:GRASP Seminar: Shlomi Laufer\, Technion – Israel Institute of Technology\, "Enhancing Surgical Skill Assessment Through Computer Vision"
DESCRIPTION:*This seminar will be held in-person in Levine 307 as well as virtually via Zoom.  \nABSTRACT\nMedical education traditionally employs the apprenticeship model\, where trainees learn directly under the supervision of experienced practitioners. This model necessitates close follow-up and typically provides extremely subjective and non- standardized feedback. Over the years\, efforts to introduce more objective assessment tools have gained momentum\, although these tools often remain time-consuming and can still be influenced by subjective evaluations. Recently\, the integration of motion sensors with medical simulators has provided a more objective form of feedback. However\, they are typically limited to different aspects of motion economy. In this presentation\, I will explore how advancements in computer vision can be utilized to create more informative assessments and feedback on surgical skills. I will also briefly discuss automatic assessment of anesthesiologists. Additionally\, I will demonstrate how introducing cameras into the operating room provides a new avenue\nfor analyzing surgical workflows.

SUMMARY:ASSET Seminar: "Machine Learning and Brain Imaging: Contributions to Diagnostics\, Prognostication\, and Treatment Guidance"
DESCRIPTION:Abstract: \nNeuroimaging has significantly expanded our understanding of brain changes in neuropsychiatric disorders as well as in aging and neurodegenerative diseases. However\, it wasn’t until the advent of machine learning tools that imaging signatures that can be detected in individuals\, rather than groups\, were constructed. More importantly\, imaging signatures derived via machine learning models have shown promise in prognostication\, as well as in guiding personalized treatments. This talk will present work on deriving imaging signatures of diagnostic and predictive value. It will then focus on weakly-supervised machine learning methods for analysis of the heterogeneity of brain imaging phenotypes\, arriving at a dimensional representation reflecting the heterogeneity of brain aging and of various brain diseases. Finally\, international consortia pooling and harmonizing large numbers of brain MRIs from many studies are presented as means for creating sufficiently large datasets for robust machine learning training and heterogeneity analysis\, but also pose new challenges\, including that or harmonization and domain adaptation across studies. \nZoom Link (if unable to attend in-person): https://upenn.zoom.us/j/92905415705

SUMMARY:Biomedical Data Science Seminar Series - "Unlocking Brain Insights: Machine Learning for Neuroimaging Studies"
DESCRIPTION:Modern neurotechnologies generate vast and intricate imaging data across multiple modalities\, capturing nuanced aspects of brain structure and function in both healthy and diseased states\, thus propelling neuroimaging into the ‘big data’ era. The quantitative analysis of such extensive neuroimaging datasets presents unprecedented opportunities for uncovering novel insights into various neuroscience problems. Machine learning and AI have emerged as promising tools for these analyses\, capable of producing personalized\, quantitative imaging-based indices with diagnostic and prognostic value\, potentially revolutionizing healthcare delivery. However\, technical challenges persist due to the high dimensionality of imaging data\, disease heterogeneity\, and the integration of these technologies into clinical workflows. In this talk\, I will discuss novel computational approaches that harness advanced machine learning techniques to tackle these challenges. First\, I will present progress toward a scalable unsupervised non-negative matrix factorization framework for interpretable and reproducible dimensionality reduction of neuroimaging data. Second\, I will delve into a deep learning framework designed to parse disease heterogeneity and generate subject-specific abnormality maps. Finally\, I will explore deep learning models aimed at overcoming obstacles in implementing AI-enabled clinical workflows. I will illustrate the broad impact of these approaches through their applications in diverse settings\, with a focus on Alzheimer’s disease.

SUMMARY:MEAM Seminar: "Elasticity of Fluids in Nanopores: Molecular Modeling and Ultrasonic Experiments"
DESCRIPTION:Fluids confined in nanopores are ubiquitous in nature and technology. In recent years\, the interest in confined fluids has grown\, driven by research on unconventional hydrocarbon resources — shale gas and shale oil\, much of which are confined in nanopores. When fluids are confined in nanopores\, many of their properties differ from those of the same fluid in the bulk. These properties include density\, freezing point\, transport coefficients\, thermal expansion coefficient\, and\, as it was shown recently\, elastic properties. \nThe elastic modulus of a fluid confined in the pores contribute to the overall elasticity of the fluid-saturated porous medium and determine the speed at which elastic waves traverse through the medium. In this talk I will show how elastic modulus of a confined fluid in a nanopore can be calculated based on Monte Carlo and molecular dynamics simulations and illustrate it with calculations for various fluids. Additionally\, I will present our recent experimental measurements of elastic properties of water confined in nanoporous glass samples. Our results suggest that some of the models widely used for describing elasticity of fluid-saturated porous solids need to be revised.

SUMMARY:BE Seminar: "Designing Programmable Protein Therapeutics with Generative Language Models" (Pranam Chatterjee\, Duke University)
DESCRIPTION:CRISPR has revolutionized biotechnology by enabling the simple design of guide RNAs to target and edit almost any DNA sequence. By developing new generative protein design algorithms\, my hybrid lab focuses on extending this CRISPR-like programmability to proteins and other key molecules. In this talk\, we will first delve into our algorithms that design binders to undruggable proteins\, such as those driving pediatric cancers (alveolar rhabdomyosarcoma and Ewing’s sarcoma) and neurodegenerative diseases (Huntington’s and Alexander Disease). Our generative language models\, including SaLT&PepPr\, PepPrCLIP\, and PepMLM\, design short binding peptides from target sequence alone\, with no dependence on stable 3D structures\, and by fusing these “guide” peptides to E3 ubiquitin ligases\, deubiquitinases\, and other modifying enzymes\, we have created a CRISPR-analogous system to edit these proteins. To be even more specific\, we train isoform-specific targeting models such as PTM-Mamba for PTM-specific binding\, FusOn-pLM for fusion oncoprotein-specific degradation\, and moPPIt for motif-specific targeting of protein-protein interactions. Inspired by the power of language models\, we further show how we can extend this programmability to DNA with our PAM-free CRISPR enzymes and our recent DPAC model\, which allows us to design proteins that can bind and modulate any DNA sequence. Moreover\, we are creating binders for heavy metals through our MetaLATTE algorithm\, aiming to sequester and detoxify metals from contaminated environments\, and addressing chemical pollutants\, such as PFAS\, by leveraging our generative models to develop proteins that can bind and degrade these persistent environmental toxins. Finally\, we will explore our long-term goal of generating new cell states with model-designed proteins\, highlighting our recent work on transcription factor-directed stem cell differentiation to ovarian cell types\, such as granulosa cells and oogonia. By combining generative design with experimental engineering\, our hybrid lab aims to translate these advances into practical applications for treating intractable diseases and addressing environmental challenges.

SUMMARY:MEAM Ph.D. Thesis Defense: "Controlling Contact Transitions for Dynamic Robots"
DESCRIPTION:Legged robots\, robotic manipulators\, and their combined embodiment as humanoid robots have received considerable attention across both academia and industry. However\, with few notable exceptions\, state-of-the-art demonstrations are significantly less dynamic than their biological counterparts. A considerable challenge towards achieving more dynamic robots lies within controlling contact interactions with their environment. Legged robots undergoing impacts experience near-instantaneous changes in their velocities\, making accurate state estimation difficult and resulting in controller sensitivity to even small deviations in impact timing. Contact transitions are also challenging for robot manipulation due to the combinatorial complexity of planning across multiple contact modes. Frictional contact that often arises from dynamic manipulation further increases this planning complexity due to the introduction of additional contact modes and increased degree of underactuation. \nTo address these limitations\, this thesis proposes algorithmic and systems contributions to gracefully handle contact transitions for dynamic robots. First\, we identify that uncertainties from impact events enter the system dynamics in a structured manner. We leverage this structure to propose a general modification to model-based feedback controllers\, enabling selective robustness to impact uncertainty while maximally retaining control authority. We validate our approach on custom dynamic jumping and running controllers on the 3D bipedal robot\, Cassie. \nThen\, we examine dexterous dynamic manipulation through complex non-prehensile tasks that require considering the full spectrum of hybrid contact modes. We leverage recent advancements in contact-implicit MPC to generate contact-rich motion plans in real-time. We demonstrate\, through careful integration of the MPC and low-level tracking controller\, how contact-implicit MPC can be adapted to dynamic tasks. We perform two distinct tasks using the same model\, notably without common aids such as reference trajectories or motion primitives\, highlighting the generality of our approach.

SUMMARY:CBE Seminar: "Pressure-induced Nanoparticle Assembly" (Hongyou Fan\, Sandia National Laboratories)
DESCRIPTION:Abstract: \nPrecise control of structural parameters through nanoscale engineering to improve optical and electronic properties of functional nanomaterials continuously remains an outstanding challenge. Previous work on nanoparticle synthesis and assembly has been conducted largely through solution chemistry at ambient pressure and relies on specific chemical or physical interactions such as van der Waals interactions\, dipole-dipole interactions\, chemical reactions\, ligand-receptor interactions\, etc. In this presentation\, I will introduce a new pressure-induced assembly and fabrication method that uses mechanical compressive force applied to nanoparticles to induce structural phase transition and to consolidate new nanomaterials with precisely controlled structures and tunable properties. By manipulating nanoparticle coupling through external pressure\, instead of through solution chemistry\, a reversible change in their assemblies and properties can be achieved and demonstrated. In addition\, over a certain threshold\, the external pressure will force these nanoparticles into contact\, thereby allowing the formation and consolidation of one- to three-dimensional nanostructures. Through pressure induced nanoparticle assembly\, materials engineering and synthesis become remarkably flexible without relying on traditional crystallization process where atoms/ions are locked in a specific crystal structure. Therefore\, morphology or architecture can be readily tuned to produce desirable properties for practical applications.

SUMMARY:ASSET Seminar: "Bridging the Gap Between Learning and Programming"
DESCRIPTION:Abstract:  \nFor decades\, we have built software by writing code\, but in recent years machine learning has emerged as a new approach to create software with features that would be impossible to code by hand. However\, the use of learning to build software risks ignoring some of the lessons we have learned for how to build computer systems that are robust and maintainable. In this talk\, I will describe a new class of techniques we have developed under the term “neurosymbolic programming” which aim to support learning while maintaining some of the benefits of traditional programming\, such as modularity\, interpretability\, reusability and incremental development\, and will show some of the benefits these techniques can offer in domains ranging from robotics to computational biology. \nZoom Link (if unable to attend in-person): https://upenn.zoom.us/j/93017587225

SUMMARY:CBE Seminar: "Self-assembly Models for Crystal Growth and Phase Transitions" (Julia Dshemuchadse\, Cornell University)
DESCRIPTION:Abstract: \nHow can we make new materials and better understand how their underlying structures form? The direct observation of crystal growth and transitions remains supremely challenging\, but gaining insight into these fundamental processes is central to our quest of creating materials in a rational and targeted way\, connecting structure to functionality. We build self-assembly models\, study how they react to perturbations on the particle and system levels\, and investigate their impact on crystal growth and transformation pathways. We use simple coarse-grained models to gain systematic insights into the phenomena that lead to the crystallization of complex crystal structures\, partial disorder\, or magic-size assemblies\, allowing us to derive the essential principles that govern the formation of materials’ structures. Our goal is to use these insights to find ways to tailor crystallization pathways and to create new functional materials. Our work promises to establish new pathways to materials design through simulations\, which explicitly incorporate and explore phase transformation kinetics.

SUMMARY:CBE Doctoral Dissertation Defense: "High-Pressure Reactions on Metals and Metal Oxides in Mesoporous Silica” (Ching-Yu Wang)
DESCRIPTION:Abstract: \nSBA-15\, a type of mesoporous silica\, is an attractive support for heterogeneous catalysts due to its high surface area\, one-dimensional uniform pore structure\, and high thermal stability. However\, modifying SBA-15 with metal and metal oxide using conventional wetness incipient impregnation is challenging. In this thesis\, Atomic Layer Deposition (ALD) was used to prepare catalysts on SBA-15. Through multiple cycles of ALD\, various metal oxides can be uniformly deposited in the pores of SBA-15 as thin films\, while maintaining the high surface area and well-defined mesoporous structure. Using vapor-phase infiltration\, i.e.\, one ALD cycle\, a wide range of metals can be efficiently incorporated into the SBA-15 pores\, exhibiting high metal loadings and metal nanoparticle sizes of 3 to 4 nm. \nThe catalytic properties of the SBA-15-supported catalysts were investigated for dehydrogenation of cycloalkanes and hydrodeoxygenation of m-cresol. While Pt/SBA-15 deactivated rapidly at low pressures due to coking\, it remained stable for long periods when the pressure was above certain critical values. These critical values depended on the pore size and structure of the support and the reaction temperature. It was demonstrated that hydrodeoxygenation of m-cresol\, a model compound for phenolics\, can be carried out over WOx-Pt/SBA-15 in a stable manner using alkanes as H2 carriers. Additionally\, cycloalkane dehydrogenation over Pt/SBA-15 was found to be stable at high pressure\, thereby providing high endothermicity. \nFinally\, the growth of metal oxides and their interactions with SBA-15 were studied. It was found that the surface silanol groups of SBA-15 were critical for stabilizing WO3 in the mesopores. CeO2 films supported by SBA-15 were more reducible than their bulk counterparts or ceria supported by Al2O3 due to a reaction between ceria and silica.

SUMMARY:MEAM Ph.D. Thesis Defense: "Enhancing Photophoretic Levitation using Three-dimensional Structures for Flight in the Mesosphere and on Mars"
DESCRIPTION:Current propulsion and flight mechanisms limit atmospheric observations. The mesosphere is too dense for satellites and too thin for typical planes and balloons\, with similar conditions found in the Martian atmosphere\, especially at Olympus Mons. Photophoresis\, the movement of gas molecules due to light\, has been studied for microscale objects like aerosols and operates optimally within the pressure ranges of these regions. When applied to ultrathin\, ultralight macroscale objects\, levitation occurs. These objects\, such as plates and disks with microstructures\, absorb visible light and heat up. The resulting temperature changes pump gas molecules through microchannels and cause a recoil force from molecules striking the hotter surface. These combined effects produce enough force to levitate centimeter-scale objects with no moving parts and only light. We designed photophoretic aircraft with 3D hollow geometries to pump ambient air through sidewalls\, creating a high-speed jet. Simulations and parametric studies optimized these geometries\, showing potential for kilogram-scale payloads for meter-scale aircraft 50 to 80 km above Earth’s surface. This included a novel theoretical framework based on previous 2D plates but expanded to 3D structures. We also fabricated millimeter-scale versions using microfabrication methods to experimentally investigate levitation in vacuum chamber experiments. Furthermore\, we developed a scalable manufacturing method for a different photophoretic aircraft with enhanced temperature gradient-induced levitation of 3D geometries made of a Mylar sandwich composite alongside a new experimental method to measure and compare photophoretic forces of solid versus porous objects. Finally\, we explored solar buoyancy\, through theory and experimental developments\, to transport the structures to the mesosphere and discussed their potential applications for carrying sensors to measure GPS and state properties in situ. Applications of this work include atmospheric science missions in the mesosphere and on Mars in collaboration with NASA.

SUMMARY:MEAM Seminar: "Programmable Strain-responsive Biopolymer Networks Adapt to High Magnitudes of Mechanical Loading"
DESCRIPTION:Biopolymer hydrogel materials typically exhibit relatively low range of programmable modulus less than 100 kPa\, which limits their biomedical applications\, such as in articular cartilage and synthetic joints\, where tissues are cyclically loaded with high magnitudes of peak stress on the order of 10MPa\, and applications in soft robotics require moduli across orders of magnitude from 1 kPa to 100 MPa. Here\, we achieved a wide range of mechanical properties with double network biopolymer hydrogels that can sustain over 10-100 MPa peak stress under repeated axial unconfined compression. Previous systems use double-network to enhance hydrogel’s toughness and strength. Here\, cryogelation generates a foam network that undergoes a rarefied to densified phase transition\, which is reinforced with a second dissipative network to yield highly tunable properties across orders of magnitude of applied stress. The foam network is formed by cryogelation of a covalently crosslinked collagen-glutaraldehyde (GA) biopolymer network that can sustain repeated loading through phase transition of its porous foam structure. Interpenetrating ionically-crosslinked alginate biopolymers tune the final modulus to make the hydrogel programmable in a high range of mechanical performance. This dual-network composite hydrogel system also exhibits reversible properties\, achieved by chelating ions to reduce ionic crosslinks or restoring crosslinks by supplying additional ions. Together\, these data demonstrate a robust hydrogel composite system adaptable to wide ranges of mechanical loading.

SUMMARY:MEAM Seminar: "Impulse-Induced Dynamic Transitions in Flexible Mechanical Metamaterials: Harnessing Nonlinear Wave Dynamics for Advanced Engineering Applications"
DESCRIPTION:Mechanical metamaterials are artificially designed structures that offer unique properties like negative Poisson’s ratio\, tunable stiffness\, and advanced thermal characteristics. While the static properties of mechanical metamaterials have been widely studied\, their nonlinear dynamics stemming from the structural and geometric designs remain largely unexplored\, which could pave ways for innovative design and optimization for novel applications related to deployable structures\, reconfigurable robots\, etc.. is to expand the fundamental understanding of flexible mechanical metamaterials and their potentials in solving engineering challenges through the combination of analytical\, numerical\, and experimental investigation. This seminar shows current findings on nonlinear dynamical behaviors\, including soliton collisions leading to phase transitions\, the preservation and disruption of topological modes under nonlinear loadings\, and the application of flexible principles in designing efficient robotic systems with enhanced motion control capabilities.

SUMMARY:MEAM Seminar: "Exploring Self-assembly of 2D Materials: Insights from Graphene Auto-kirigami"
DESCRIPTION:Two dimensional (2D) materials with atomic-scale thickness like graphene exhibit substantial in-plane stiffness and strength while maintaining significant out-of-plane flexibility. This enables the assembly of graphene into complex multilayer and even three-dimensional (3D) structures through a unique combination of self-folding\, self-tearing\, and nearly frictionless self-propagation\, all driven by interfacial energy. We call this phenomenon ‘graphene auto-kirigami’. \nAuto-kirigami provides an innovative approach to potentially sculpting 2D materials into intricate micro/nanostructures. However\, significant challenges exist in understanding and controlling it. To address this\, we have probed graphene auto-kirigami with atomic force microscopy (AFM) experiments\, continuum mechanics models\, and molecular dynamics (MD) simulations. We will present results toward our goal of developing a complete\, atomistically-informed physical description of auto-kirigami formation in graphene-based systems.

SUMMARY:MEAM Seminar: "Towards Understanding Tactile Sensing Across the Robot Manipulation Stack"
DESCRIPTION:Humans are exceptionally skilled at manipulating a diverse range of objects\, apparent from the order of magnitude difference in sizes\, weight distributions\, stiffnesses\, and geometries of items we use on a daily basis. For robots to seamlessly integrate into a world centered around human dexterity\, they must also possess comparable manipulation abilities. My research aims to address this challenge by exploring and understanding how tactile sensing can contribute to robot manipulation across the stack in sensor design\, perception\, and control. First\, we leverage a selectively transmissive soft membrane for a novel tactile and proximity sensor that offers uncompromised spatial resolution in both modalities. Then\, we explore how to fuse the tactile and proximity modalities to extract contact patches from extreme deformations of the soft sensing surface\, extending functionality to new deformation regimes. Finally\, I will conclude with our work on an RL-tractable tactile skin model that enables zero-shot sim2real transfer of ternary shear and binary normal forces\, which we use to develop an RL policy for dexterous in-hand translation.

SUMMARY:MEAM Seminar: "Soft Pneumatic Force Application through Membrane Design and Stiffness Control"
DESCRIPTION:Modern robotic platforms are designed for precision\, but their cost and rigidity make them impractical for many at-home physical human-robot interaction (pHRI) applications. Soft pneumatic actuators (SPA) have potential as safe and affordable means of providing comfortable force application for use in pHRI\, but lack shape planning and control during contact. In this seminar\, we will discuss electroadhesive clutches as a novel strain limiter for soft membranes and their applications in real-time programming of inflation trajectory and force response. We outline our force-pressure characterization for a heterogeneous SPA membrane design\, the use of autonomous experimentation for design parameter exploration\, and our vision for applications in pHRI for the elderly or those with significant medical ailments.
