SUMMARY:ASSET Seminar: "Lifelong Learning for Autonomous Systems: Progress and Challenges" (Eric Eaton\, University of Pennsylvania)
DESCRIPTION:ABSTRACT: \nResearch in lifelong or continual machine learning has advanced rapidly over the past few years\, primarily focusing on enabling learned models to acquire new tasks over time while avoiding catastrophic forgetting of previous tasks. However\, autonomous systems still lack the ability to rapidly learn new generalizable skills by building upon and continually refining their learned knowledge—a hallmark of lifelong learning in humans and animals. In this talk\, I will examine our progress toward lifelong machine learning and its application to autonomous systems\, exploring recent work in compositional representations and self-supervision. We’ll then discuss how far we have come and the open problems that remain toward learning generalizable skills in lifelong settings. \n  \nZOOM LINK (if unable to attend in-person): https://upenn.zoom.us/j/94522983788

SUMMARY:MEAM Seminar: "Collective Transitions in Beating Cilia and Swimming Fish"
DESCRIPTION:I will discuss the collective modes that spontaneously emerge in ciliary carpets and fish schools. In both systems\, the fluid medium couples the motion of individuals in the group. Flow coupling is dominated by viscous forces in cilia and by inertial interactions in fish. I will show\, numerically and analytically in the continuum limit\, that the waves that emerge in ciliary carpets are robust to morphological and kinematic perturbations of the ciliated tissues. In fish schools\, I will show intermittent collective behavior with back-and-forth switching between schooling and milling\, and I will analyze the bifurcations underlying phase transitions by lifting the stochastic dynamics of individual fish onto a Fokker-Planck equation that governs the group dynamics. These problems highlight how structure\, activity\, and environment interconnect to produce emergent biological function; our work provides a framework for establishing structure-to-function maps across multiple length scales to help understand\, probe\, and engineer emergent phenomena in biological and biomedical systems.

SUMMARY:MEAM Master's Thesis Defense: "Modeling Off-Grid Photovoltaics Integrated with Micro-Cogeneration and Electrical Energy Storage"
DESCRIPTION:Due to the elevated expenditure of fossil fuels and their adverse impacts on climate change resulting from greenhouse gas emissions\, it is imperative to integrate clean energy sources alongside fossil fuels. This study presents the design\, simulation\, and optimization of an integrated system comprising solar photovoltaics\, micro-cogeneration\, and electrical energy storage to achieve energy self-sufficiency independently from external energy sources. Moreover\, the study determines the maximum cost of the converter that can be economically added to the heating system\, enabling it to generate both heat and electricity simultaneously. It also calculates the unit electricity cost for each combination. The modeled system is capable of meeting all required electricity and heat demands. Yet\, the model presents a range of alternatives for configuring the capacity required for PV panels\, batteries\, and converter\, each resulting in varied overall costs. It has been determined that when conversion efficiency increases\, the costs associated with PV panels and batteries decrease\, as do the overall cost. However\, the maximum cost of the converter necessary for achieving cost-effectiveness is not constant\, but rather changes according to its efficiency. Ultimately\, the unit electricity cost varies\, decreasing with increasing converter rated power until a certain value\, then increasing.

SUMMARY:PICS Colloquium: "Representations Learnt from Synthetic Volumes Enable Training-free Medical Image Analysis"
DESCRIPTION:Current medical image analysis projects involve months to years of data annotation and custom technical development. This talk introduces methods to train networks that generalize out-of-the-box to new modalities\, anatomies\, and datasets all without retraining for the specific use case. Our key contributions include (A) generative models driven by biomedical shape priors that synthesize wildly variable training data\, and (B) a multi-scale dense representation learning algorithm that leverages the synthetic data to learn contrast-invariant representations. We will show that a single U-Net pretrained in this manner can then extract features that enable state-of-the-art 3D multimodality image registration and can also serve as a general-purpose foundation model for few-shot segmentation across arbitrary biomedical datasets. We will also briefly demonstrate translational applications of the proposed methods to ongoing studies of disordered pregnancies in fetal and maternal MRI.

SUMMARY:MEAM Master's Thesis Defense: "The Rheology and Microphysics of Monodisperse Synthetic Mucin"
DESCRIPTION:Mucus\, a complex fluid produced by every living organism\, has multiple essential functions including acting as an effective barrier layer in various bodily processes\, many of which involve important rheological (flow) and tribological (adhesive\, lubricative) functions. The primary component of mucuses are mucins – highly glycosylated\, linear polypeptides. Understanding how the structure and properties of mucins control the overall behavior of mucus is thus of substantial interest. However\, natural mucus is often contaminated with non-mucin constituents that affect the rheological response\, and purifying mucus without damaging the mucins themselves is difficult. Here\, fully synthetic\, monodisperse mucins have been prepared by a collaborator. Aqueous solutions of these mucins have been studied for comparison to the rheological response shown by natural mucin solutions. The purity and structural control of these synthetic mucins provide a model system where the mechanistic sources of the mucus’ rheological response can be isolated and identified. Experimental bulk rheometry demonstrates a shear-thinning behavior with a yield-stress fluid response. This behavior is attributed to associations between mucin molecules localized to the liquid-air interface\, which contradicts previous literature on natural mucins. This conclusion is supported by interfacial rheology measurements and by a mathematical model encapsulating the dynamics of a thin mucin layer under shear. This work furthers the understanding of the dynamics of mucin solutions and the qualitative microphysics surrounding their dynamics.

SUMMARY:Spring 2024 GRASP on Robotics: Marco Pavone\, Stanford University & NVIDIA\, "Rethinking AV Development with AV Foundation Models"
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. \nABSTRACT\nFoundation models\, trained on vast and diverse data encompassing the human experience\, are at the heart of the ongoing AI revolution influencing the way we create\, problem solve\, and work. These models\, and the lessons learned from their construction\, can also be applied to the way we develop a similarly transformative technology\, autonomous vehicles. In this talk\, I will highlight recent research efforts towards rethinking elements of an AV program both in the vehicle and in the data center\, with an emphasis on (1) composing ingredients for universal and controllable end-to-end simulation\, (2) architecting autonomy stacks that leverage foundation models to generalize to long-tail events\, and (3) ensuring safety with foundation models in the loop.

SUMMARY:PRECISE Seminar: Optical Coherence Tomography - From Conception to Current Frontiers
DESCRIPTION:Optical coherence tomography (OCT) is a technology invented in 1991 to image small critical tissue structures throughout the body with micrometer resolution. It is widely used in the management of eye and coronary heart diseases. In 2023\, OCT received broad attention when its inventors received the prestigious Lasker-DeBakey Clinic Medical Research Award and the National Medal of Technology and Innovation from President Biden. For me\, it was the culmination of 3 decades of work as an engineer\, clinician\, and translational researcher\, as well as an even longer journey as an immigrant who tapped into the potential of America’s great research universities. \nI will present OCT from an inventor’s perspective. The physical principles will be explained with illustrations on measuring the time-of-flight of light with interferometry. I will tell the story of the aha moment when the idea of OCT came to my mind\, as well as the rapid pace of development that made OCT a clinical reality. The biggest applications of OCT in the management of eye diseases will be shown. Recent advances made at OHSU that enable OCT to advance beyond the imaging of tissue structure to the detection of blood flow and photoreceptor function will be described. \nOCT is still a rapidly developing technology. The technical capabilities have improved in many aspects\, but the most astounding has been the continual improvement in imaging speed\, which has doubled approximately every 2.5 years over the past 3 decades. The technological advances have made more and more clinical applications feasible. I will present a vision for the broader applications of OCT\, which includes imaging the eye to assess brain and cardiovascular diseases\, as well as direct OCT imaging of other target organs such as the skin\, digestive tract\, brain\, inner/middle ear\, and teeth.

SUMMARY:MSE Seminar: "Probabilistic Digital Twins for Structure Preserving Simulation and Scientific Discovery"
DESCRIPTION:Despite the recent flurry of work employing machine learning to develop surrogate models to accelerate scientific computation\, the “black-box” underpinnings of current techniques fail to provide the verification and validation guarantees provided by modern finite element methods. In this talk we present a data-driven finite element exterior calculus for building accelerated reduced-order models of multiphysics systems when the governing equations are either unknown or require closure. Key to the framework is a fully differentiable partition of unity which provides a machine learnable alternative to a traditional computational mesh\, upon which we simultaneously learn physical relevant control volumes alongside corresponding integral balance laws. We demonstrate that resulting models may realize speedup of over 1000x over traditional finite element simulations\, while guaranteeing the exact treatment of physical constraints and numerical stability. We then briefly summarize recent work developing Bayesian underpinnings for these models\, providing characterization of epistemic uncertainty which may be used to drive active learning tasks. \nWith tools for building probabilistic digital twins in hand\, we then turn to our work integrating physical models into high-throughput material discovery experiments to characterize process-structure-property relationships. In material science\, datasets are comparatively small relative to the combinatorially massive space of potential designs. We combat this by fusing information spanning multimodal characterization (e.g. XRD\,TEM\,SEM\,EBSD) of differing fidelity and throughput and incorporating data-driven models. We end by summarizing some campaigns conducted at Sandia National Laboratories applying these tools to physical vapor deposition\, metal additive manufacturing\, and electrodeposition.

SUMMARY:John A. Quinn Distinguished Lecture in Chemical Engineering: "Exploring the Physics\, Materials Science\, and Biological Implications of Polyelectrolyte Complexation" (Matthew Tirrell\, University of Chicago)
DESCRIPTION:Abstract\nThe richness of liquid-liquid phase separation behavior in mixtures of oppositely-charged polyelectrolyte has been greatly illuminated recently in the polymer physics literature. Precise determinations of phase diagrams\, measurements of interfacial tension\, scattering measurements of chain configurations\, and increasingly insightful theory are all producing a clearer understanding of these phenomena. In parallel\, physics is also being brought to bear on manifestations of these behaviors in biology. Diverse biological examples related to liquid0liquid phase separation of polyelectrolyte complexes include membraneless organelles\, biological condensates that enhance transcription or protect from stress shock\, and other biological functions. This talk will spell out current understanding of the various contributions to the phase behavior\, including the role of various entropic contributions\, as well as the effects of charge density of the macromolecules. New\nresults on asymmetric mixtures will be presented\, which are more the norm in nature than the perfectly symmetrical mixtures in polymer physics studies.

SUMMARY:Spring 2024 GRASP SFI: Harish Ravichandar\, Georgia Institute of Technology\, "New Wine in an Old Bottle: A Structured Approach to Democratize Robot Learning"
DESCRIPTION:This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nDecades of rigorous research in dynamical systems and control helped us integrate robots into a wide variety of domains\, ranging from factory floors to the moon. Today\, it would appear that deep learning has taken over the torch and will bring robots to our homes\, freeing us all from banal chores. In this utopian vision\, learning-based approaches tend to replace analytical methods. Moving away from handcrafted bespoke solutions to generalist robots that can operate in unstructured environments. But one can instead view learning-based and analytical approaches as two ends of a broad spectrum\, with one end optimizing for reliability (at the cost of human effort) and the other for emergent intelligence (at the cost of data and computation). In this talk\, I will argue why it is better for robots to be in the middle of this broad spectrum. Using manipulation as a case study\, I will discuss how our lab combines ideas from dynamical systems and machine learning to overcome three often-overlooked issues with contemporary methods: i) high barrier to entry due to demands for expensive computational resources and annotated data\, ii) inability to handle new tasks without relying on significant user expertise (e.g.\, for reward or controller design\, hyperparameter tuning\, data collection and curation)\, and iii) unreliable behaviors due to inscrutable and unpredictable learned policies. Addressing these issues will enable robot learning to escape the confines of well-resourced research labs and positively impact the larger society.

SUMMARY:ASSET Seminar: "Statistical Methods for Trustworthy Language Modeling" (Tatsu Hashimoto\, Stanford University)
DESCRIPTION:ABSTRACT: \nLanguage models work well\, but they are far from trustworthy. Major open questions remain on high-stakes issues such as detecting benchmark contamination\, identifying LM-generated text\, and reliably generating factually correct outputs. Addressing these challenges will require us to build more precise\, reliable algorithms and evaluations that provide guarantees that we can trust. \nDespite the complexity of these problems and the black-box nature of modern LLMs\, I will discuss how in all three problems — benchmark contamination\, watermarking\, and factual correctness — there are surprising connections between classic statistical techniques and language modeling problems that lead to precise guarantees for identifying contamination\, watermarking LM-generated text\, and ensuring the correctness of LM outputs. \n  \nZOOM LINK (if unable to attend in-person): https://upenn.zoom.us/j/94597712175

SUMMARY:PICS Colloquium: "Exploiting time-domain parallelism to accelerate neural network training and PDE constrained optimization"
DESCRIPTION:This talk will explore methods for accelerating numerical optimization constrained by transient problems using parallelism. Two types of transient problems will be considered. In the first case training algorithms for Neural ODEs will be discussed. Neural ODEs are a class of neural network architecture where the depth of the neural network (the layers) is modeled as a continuous time domain. For the second case\, transient PDE-constrained optimization problems will be described. In either case\, simulation-based optimization requires repeated executions of the simulator’s forward and backward (adjoint) time integration schemes. Consequently\, the arrow of time creates a major sequential bottleneck in the optimization process. Second\, for performance these methods rely strongly on the available parallelization for the forward and adjoint solves. Thus\, when forward and adjoint solvers are already operating at the limit of strong scaling and hardware utilization\, the arrow-of-time bottleneck cannot be overcome by additional parallelization across the spatial grid or network layers.  \nDeep neural networks are a powerful machine learning tool with the capacity to‚ learn complex nonlinear relationships described by large data sets. Despite their success training these models remains a challenging and computationally intensive undertaking. We will present a layer-parallel training algorithm that exploits a multigrid scheme to accelerate both forward and backward propagation. Introducing a parallel decomposition between layers requires inexact propagation of the neural network. The multigrid method used in this approach stitches these subdomains together with sufficient accuracy to ensure rapid convergence. We demonstrate an order of magnitude wall-clock time speedup over the serial approach\, opening a new avenue for parallelism that is complementary to existing approaches. We also discuss applying the layer-parallel methodology to recurrent neural networks and transformer architectures.  \nThe second half of this talk focuses on PDE-constrained optimization formulations. Solving optimization problems with transient PDE-constraints is computationally costly due to the number of nonlinear iterations and the cost of solving large-scale KKT matrices. These matrices scale with the size of the spatial discretization times the number of time steps. We propose a new 2-level domain decomposition preconditioner to solve these linear systems when constrained by the heat equation. Our approach leverages the observation that the Schur-complement is elliptic in time\, and thus amenable to classical domain decomposition methods. Further\, the application of the preconditioner uses existing time integration routines to facilitate implementation and maximize software reuse. The performance of the preconditioner is examined in an empirical study demonstrating the approach is scalable with respect to the number of time steps and subdomains.

SUMMARY:MEAM Master's Thesis Defense: "Gaussian Process-Based Active Exploration Strategies in Vision and Touch"
DESCRIPTION:Robots struggle to understand object properties like shape\, material\, and semantics due to limited prior knowledge\, hindering manipulation in unstructured environments. In contrast\, humans learn these properties through interactive multi-sensor exploration. This work proposes fusing visual and tactile observations into a unified Gaussian Process Distance Field (GPDF) representation for active perception of object properties. While primarily focusing on geometry\, this approach also demonstrates potential for modeling surface properties beyond geometry. \nThe GPDF encodes signed distance\, gradients\, and uncertainty estimates. Starting with an initial visual shape estimate\, the framework iteratively refines the geometry by integrating dense vision measurements using differentiable rendering and tactile measurements at uncertain regions. By quantifying multi-sensor uncertainties\, it plans exploratory motions to maximize information gain for recovering precise 3D structures. To improve scalability\, it investigates approximation methods like inducing point parameterization for Gaussian Processes. This probabilistic multi-modal fusion enables active exploration and mapping of complex object geometries.

SUMMARY:MEAM Seminar: "Flows About Superhydrophobic Surfaces"
DESCRIPTION:Superhydrophobic surfaces\, formed by air entrapment within the cavities of hydrophobic solid substrates\, offer a promising potential for hydrodynamic drag reduction. In several of the prototypical surface geometries the flows are two-dimensional\, governed by Laplace’s equation in the longitudinal problem and the biharmonic equation in the transverse problem. Moreover\, low-drag configurations are typically associated with singular limits. Accordingly\, the analysis of liquid slippage past superhydrophobic surfaces naturally invites the use of both singular-perturbation methods and conformal-mapping techniques. I will discuss the combined application of these methodologies to several emerging problems in the field.

SUMMARY:MEAM Master's Thesis Defense: "Optical Analysis of Buckling-Induced Micro-Robotic Membranes"
DESCRIPTION:In recent years\, micro-robotic membranes have attracted increasing interest due to their unique properties and potential applications in various fields. The optical properties of these membranes have been playing a crucial role in the design and development of optical devices such as reflective displays with customizable colors. The primary challenge to understanding the mechanical-spectral interaction is the limitation of conventional microscopic techniques. The AFM cannot be employed when voltage is applied. Conversely\, hyperspectral imaging offers insights into the spectral response but lacks the capacity to infer topological characteristics directly. In this research\, I build an optical model that stands on the theoretical foundation laid by Maxwell’s equations\, Fresnel equations\, and the Transfer Matrix Method (TMM). By feeding the hyperspectral imaging\, the model can reconstruct the 3D topologies of buckling membranes. This is achieved through least-square regressions to accurately predict height data across various points. Through this methodology\, this research offers a novel framework for understanding the complex interplay between mechanical deformation and optical phenomena.

SUMMARY:CBE Doctoral Dissertation Defense: "Identifying Material Fingerprints of Relevance to Understand Adsorbate-Surface Interactions Using First Principles Modeling and Machine Learning" (Genesis Quiles-Galarza)
DESCRIPTION:Abstract: \n\n\n\nAdsorption of chemical species on surfaces of materials is one of the critical phenomenon governing the reactivity and activity of the material for surface and interface driven chemical reactions. At the core of the analytical $d$-band adsorption model is the correlation between the adsorption energy of a chemical species (molecule or reaction intermediate) on the metal surface and an electronic material property\, namely the d-band center from the density of states (DOS). Although very successful\, the d-band model has its limitations and cannot be applied to all materials. Therefore\, efforts have been devoted to discover material fingerprints that can be used to describe adsorption of chemical species on more complex surfaces and materials. Herein\, we use first principles methods (density functional theory\, DFT) and machine learning (ML) to elucidate what kind of material fingerprints or features are needed to describe the interaction between an adsorbate and the surface of a metal material\, a two-dimensional (2D) transition metal carbide and nitride compound materials known as MXenes\, and a hybrid (molecular catalyst supported on a heterogeneous surface) catalyst material. The ML models used in this study belong either to the “black-box” or “glass-box” category\, enabling not only prediction of the adsorption energy with small errors\, but also allow insight into the material physics governing the adsorbate-surface interaction. These ML studies indisputably demonstrate that the electronic fingerprints of the material are the most critical features in reliably determining the adsorbate-surface interactions.For metals\, we confirm the findings of the analytical d-band model by achieving adsorption formulas with contributions from both the sp and d-DOS bands\, as well as multiple higher order contributions. For MXenes\, we find that the adsorbate-surface interaction is complex with significant contributions from the terminating functional group atom\, specifically their sp-DOS band features. Generally\, our studies shows that the nature of the adsorbate-surface interactions cannot be fully captured by single or simple linear correlations between the adsorbate energy and a materials feature\, but instead require higher order\, multi-dimensional feature combinations. These findings imply that further investigations are needed to develop physically-sound\, multi-dimensional features which could be used as descriptors to predict adsorbate-surface interactions with an accuracy comparable to that of DFT.

SUMMARY:PICS Colloquium: "Physics-compatible kinetic-energy and entropy preserving (KEEP) scheme for high-fidelity simulation of compressible turbulence"
DESCRIPTION:Low (or ideally zero) numerical dissipation is always critical for high-fidelity scale-resolving flow simulations\, as numerical dissipation prevents the physics of inviscid kinetic energy and entropy conservation\, which is an essential attribute of compressible turbulence. However\, contrary to the requirement\, numerical schemes in compressible flow heavily rely on numerical dissipation for stable computation\, preventing high-fidelity simulations\, especially for flows around complex geometries. We address this challenge by devising a physics-compatible numerical scheme that satisfies the kinetic energy and entropy preservation (KEEP) properties by discretely satisfying the analytical relations of the governing equations. The KEEP scheme is highly stable without introducing numerical dissipation\, something that existing numerical schemes fail to do. The stability stems from the significant improvement of entropy preservation in the KEEP scheme. The KEEP scheme allows robust and high-fidelity simulation not only for academic purposes but also for engineering applications with complex geometries. We also discuss an illustrative application to near-stall flows around complex full aircraft configurations with high-lift devices to show the capability of our numerical framework.

SUMMARY:Spring 2024 GRASP on Robotics: Kristi Morgansen\, University of Washington\, "Integrated Sensing and Actuation for Robust Flight Systems"
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. \nABSTRACT\nA fundamental element of effective operation of autonomous systems is the need for appropriate sensing and processing of measurements to enable desired system actions. Model-based methods provide a clear framework for careful proof of system capabilities but suffer from mathematical complexity and lack of scaling as probabilistic structure is incorporated. Conversely\, learning methods provide viable results in probabilistic and stochastic structures\, but they are not generally amenable to rigorous proof of performance. A key point about learning systems is that the results are based on use of a set of training data\, and those results effectively lie in the convex hull of the training data. This presentation will focus on use of model-based nonlinear empirical observability criteria to assess and improving and bounding performance of learning pose (position and orientation) of rigid bodies from computer vision. A particular question to be addressed is what sensing data should be captured to best improve the existing training data. The particular tools to be leveraged here focus on the use of empirical observability gramian techniques being developed for nonlinear systems where sensing and actuation are coupled in such a way that the separation principle of linear methods does not hold. These ideas will be discussed relative to both engineering applications in the form of motion planning for range and bearing only navigation in autonomous vehicles\, vortex position and strength estimation from pressure measurements on airfoils\, and effective strain sensor placement on insect wings for inertial measurements.

SUMMARY:BE Seminar: "Using Computers to Derive Protein Structure from Sparse Data – A Case Study for Mass Spectrometry" (Steffen Lindert\, Ohio State)
DESCRIPTION:Mass spectrometry-based methods such as covalent labeling\, surface induced dissociation (SID) or ion mobility (IM) are increasingly used to obtain information about protein structure. However\, in contrast to other high-resolution structure determination methods\, this information is not sufficient to deduce all atom coordinates and can only inform on certain elements of structure\, such as solvent exposure of individual residues\, properties of protein-protein interfaces or protein shape. Computational methods are needed to predict high-resolution protein structures from the mass spectrometry (MS) data. Our group develops algorithms within the Rosetta software package that use mass spectrometry data to guide protein structure prediction. These algorithms can incorporate several different types of mass spectrometry data\, such as covalent labeling\, surface induced dissociation\, and ion mobility. We developed scoring functions that assess the agreement of residue exposure with covalent labeling data\, the agreement of protein-protein interface energies with SID data and the agreement of protein model shapes with collision cross section (CCS) IM measurements. We subsequently rescored Rosetta models generated with de novo protein folding and protein-protein docking and we were able to accurately predict protein structure from MS labeling\, SID and IM data. Future work is focusing on developing custom machine learning models to predict protein structure from MS data.

SUMMARY:ESE Spring Seminar - "Miniaturized Biomedical Devices for Navigation\, Sensing and Stimulation"
DESCRIPTION:Medical electronic devices are an integral part of the healthcare system today and are used in a variety of applications around us. The design of such devices has several stringent requirements\, the key being miniaturization\, low-power operation\, and wireless functionality. In this talk\, I will present CMOS-based miniaturized\, low-power and wireless biomedical devices in three broad domains: (a) in-vivo navigation and tracking\, (b) in-vivo sensing of biomarkers and physiological signals\, and (c) in-vivo stimulation and drug delivery. For the first part\, I will talk about ingestible and implantable devices that can be used to achieve sub-mm tracking accuracy in 3D and in real time inside the human body\, which is very useful for localizing devices in the GI tract\, during precision surgeries and minimally invasive procedures. In the second part\, I will present the design of a novel on-chip 3D magnetic sensor that is highly miniaturized and low-power\, thus making it suitable for many biomedical applications. In the last part\, I will briefly talk about my recent work on a wearable device for multi-modal sensing from sweat\, followed by ongoing work on devices for stimulation and drug-delivery in the GI tract. I will end the talk with a glimpse of my future research direction.
