SUMMARY:SIG Seminar: "Physics-based Animation at Pixar"
DESCRIPTION:Pixar’s films rely heavily on physically simulated effects such as the motion of hairs\, cloth\, and water\, to cite a few. Whereas physical accuracy is of paramount importance in engineering applications\, the most important aspects of feature film productions are directability and speed. In this talk\, I’ll survey our recent work in this area\, including robust hyperelastic materials model for volume simulation and high-performance physically-based sculpting techniques.

SUMMARY:PICS Colloquium: "Data-driven model reduction and multiscale modal decomposition for complex chaotic systems"
DESCRIPTION:Many complex nonequilibrium systems\, including turbulent flows\, are characterized by chaotic dynamics\, a large number of degrees of freedom\, and hierarchical\, multiscale structure in space and time. In two vignettes\, we describe some recent work aimed at developing and applying machine learning and data science tools for systems displaying these characteristics. \nThe first vignette builds on the idea that while partial differential equations are formally infinite- dimensional\, the presence of energy dissipation drives the long-time dynamics onto a finite-dimensional invariant manifold sometimes called an inertial manifold (IM).  We describe a data-driven framework to represent chaotic dynamics on this manifold and illustrate it with data from simulations of the Kuramoto-Sivashinsky equation. A hybrid method combining linear and nonlinear (neural-network) dimension reduction transforms between coordinates in the full state space and on the IM. Additional neural networks predict time evolution on the IM; this can be done in either the discrete-time (difference equation) or continuous-time (ordinary differential equation) setting. The formalism accounts for translation invariance and energy conservation\, and substantially outperforms linear dimension reduction\, reproducing very well key dynamic and statistical features of the attractor. \nThe second vignette addresses how to represent flow or other fields with multiscale structure. We describe a method\, inspired by wavelet analysis\, that adaptively decomposes a dataset into an hierarchy of structures (specifically orthogonal basis vectors) localized in scale and space: a “data-driven wavelet decomposition”. This decomposition reflects the inherent structure of the dataset it acts on. In particular\, when applied to turbulent flow data\, it reveals spatially localized\, self-similar\, hierarchical structures. It is important emphasize that self-similarity is not built into the analysis\, rather\, it emerges from the data. This approach is a starting point for the characterization of localized hierarchical turbulent structures that we may think of as the building blocks of turbulence. It will also find application to other systems\, such as atmospheres\, oceans\, biological tissues\, active matter and many others\, that display multiscale spatiotemporal structure. \n  \n

SUMMARY:PICS Seminar: "Simulating solids like fluids:  A fully Eulerian approach to fluid-structure interaction"
DESCRIPTION:Abstract: Fluids and solids tend to be addressed using distinct computational perspectives.  Solid deformation is most commonly simulated with Lagrangian finite-element methods\, whereas fluid flow is amenable to Eulerian-frame approaches such as finite difference and finite volume methods.  Problems that mix fluid and solid behaviors simultaneously present interesting numerical challenges.   Here we focus on fluid-structure interaction (FSI) problems\, and discuss an emerging method called the Reference Map Technique\, which allows us to simulate deformable solids on a fixed Eulerian grid.  The key is to store and update the reference map field on the grid\, which tracks the inverse motion.  Using this technique to represent the solid phase\, we can solve all phases of an FSI problem on a single fixed grid using fast update procedures very similar to those used in two-phase Navier-Stokes fluid simulations.   Various solid constitutive behaviors can be used\, such as nonlinear elasticity and plasticity.  Systems of many submerged and interacting solids can be simulated\, and\, by activating the solids internally\, we can simulate systems of “soft swimmers”.  Incompressibility and rigidity constraints can be applied in all phases by adopting Eulerian projection approaches commonly used in CFD.  The addition of the reference map field to the grid also presents certain benefits when computing level-set interface advection\, including a procedure to guarantee mass conservation. \n

SUMMARY:MEAM Seminar: "Data-driven Physics Discovery and Scale Bridging in Materials"
DESCRIPTION:In this talk I will provide an overview of our recent work in data-driven methods—mainly machine learning—to enhance computational materials physics models. This body of work has proceeded along two main fronts. The first is system inference\, where we seek to identify physical mechanisms via their mathematical signatures as differential or algebraic operators. Our approach of Variational System Identification leverages the weak form of partial differential equations to identify the physics underlying pattern formation\, and the deformation mechanisms of soft materials. The framework of Variational System Identification has to address several challenges specific to experimental characterization of materials\, such as data that is noisy\, sparse\, originates from different specimens\, and spans dynamics to steady state regimes. The second front is in scale bridging\, which we approach in the context of determining free energy functions. We have developed Integrable Deep Neural Networks\, and active learning algorithms to combine data generated by Density Functional Theory calculations with cluster expansions and Monte Carlo computations to obtain free energy density functions. These are used in mechano-chemically coupled continuum methods to predict the evolution of microstructure in alloys.

SUMMARY:ESE Seminar: "High-Frequency Power Conversion with Wide-Bandgap Semiconductors"
DESCRIPTION:With the commercialization of wide-bandgap power semiconductors\, multi-MHz switching frequencies are more compelling and critical to meet new applications demanding leaps in power density and efficiency. In the past\, studies of these converters reported significant gaps between measured and modeled performance\, often attributed to dynamic RDS\,ON in GaN HEMTs. In particular\, the power semiconductors – which often drive thermal constraints – dissipated much more power than expected\, rendering designs based on simulated values unusable. In soft-switched converters\, which dominate at MHz frequencies\, the semiconductor’s output capacitor is resonantly charged and discharged once per switching cycle. Recently\, multiple papers have found significant losses from this process in silicon and wide-bandgap devices\, explaining the unexpected power dissipation. With these losses known\, the MHz-frequency design space can be reopened – if designers are careful about semiconductor selection. In this talk\, I will discuss how to select the right device across material (GaN\, SiC\, or Si)\, device technology (superjunction or trench)\, size (lower RDS\,ON is not always better)\, and\, in some cases\, manufacturer. Further\, I will show how this selection drives thermal design\, input voltage selection\, and novel circuit topologies in a variety of high-performance demonstrations from 6.78 MHz all the way to 40.68 MHz.

SUMMARY:CIS Seminar: "Advances in Machine Learning Systems Research"
DESCRIPTION:A long-standing grand challenge in computing is to enable machines to act autonomously and intelligently: to rapidly and repeatedly take appropriate actions based on information in the world around them. Driven by trends in the data economy\, rapid progress in AI\, and an increasingly programmable physical world we are at an inflection point that demands a new class of AI system. This new class of systems goes beyond training models at scale\, to connecting models with the world\, rendering predictions in real-time under heavy query load\, adapting to new observations and contexts. These systems will need to be composable and elastically scalable to accommodate new technologies and variations in workloads. Operating in the physical world\, observing intimate details of our lives\, and making critical decisions\, these systems must also be secure. \nIn this talk\, I will present work in my group exploring advances in systems for prediction serving\, autonomous driving\, and how model design and system design interact.  In particular\, I will discuss some of the key trade-offs between time\, accuracy\,  convergence\, throughput\, and security that govern how we design systems\, train models\, and make predictions that meet the demands of real-world applications.

SUMMARY:CBE Seminar: "Antibiotic Discovery by Means of Computers"
DESCRIPTION:Abstract \nUntil now\, the natural world has supplied us with antibiotics. Bacteria\, however\, are increasingly resistant to these drugs. The next generation of antibiotics will likely come not from nature but from computer-based discovery. Computer-driven approaches have the potential to outperform humans\, as demonstrated for pattern recognition of images and text. In order for machines to discover novel drugs and optimize antimicrobial properties\, they have to be able to understand\, read and write molecules. In this talk\, I will describe our efforts in developing computational approaches for antibiotic discovery. I will discuss how we trained a computer to execute a fitness function following Darwin’s algorithm of evolution to select for structures that interact with bacterial membranes\, yielding the first artificial antimicrobials that kill bacteria both in vitro and in animal models. My lab has also developed pattern recognition algorithms to mine the human proteome\, identifying throughout the body thousands of antibiotics encoded in proteins with unrelated biological function. Computer-made drugs may help to replenish our arsenal of effective drugs.

SUMMARY:PICS Seminar: "Shock-induced turbulent mixing and interactions with flexible panels through simulations"
DESCRIPTION:Two fundamental challenges that arise in the development of air-breathing supersonic combustion ramjet engines (scramjets) for hypersonic flight are: 1) the rapid mixing of fuel and oxidizer that must occur prior to combustion\, and 2) the coupling between the engine structure and the flow dynamics. Interactions of shock waves and turbulence that characterize the flow inside scramjets play a key role in both mixing enhancement and aerostructural coupling. We present ongoing efforts on the high-fidelity numerical simulation of these two phenomena. \nScalar mixing under canonical shock-turbulence interactions will be addressed first by means of Direct Numerical Simulation\, evaluating the effects of variations in the relevant physical parameters: shock and turbulence Mach numbers\, Reynolds number\, and Schmidt numbers. The analysis will highlight changes along the shock-normal direction of scalar variance and dissipation-rate budgets\, flow topology\, and alignments of the scalar gradient with vorticity and strain-rate eigendirections. \nThen\, we will focus on interactions of shock waves reflecting off turbulent boundary layers that develop along the walls of the scramjet. Rigid and flexible walls will be considered\, by coupling a wall-modeled large-eddy simulation solver for the fluid flow with an elastic solid structural solver that accounts for geometric nonlinearities. We will emphasize strong shock/boundary-layer interactions resulting in mean flow separation and low-frequency unsteadiness that can interact with natural frequencies of the structure.

SUMMARY:MEAM/GRASP Seminar: "Saltatorial Locomotion on Terrain Obstacles"
DESCRIPTION:Robots often struggle to move through complicated environments from cluttered living spaces to treetop canopies where humans and animals flit with ease. Jumping is an exciting locomotion mode that can enable small ground-based robots to maneuver around large obstacles and gaps in complicated environments. A high-power jumping robot can rapidly traverse obstacles\, but the resulting fast and forceful stance phases are challenging for control and estimation. In this talk\, I will present my work developing a small monopedal jumping robot\, Salto-1P: Saltatorial Locomotion on Terrain Obstacles. Salto-1P achieved superlative jumping performance and demonstrated the first robotic wall jump\, extreme-acceleration hopping\, precise control to traverse obstacles much larger than the robot’s size\, and onboard estimation and control to operate outdoors and execute balanced landings.

SUMMARY:CBE Seminar: "Delineating Mechanisms of BMP-mediated Patterning and Organization During Development Through Integrative Experiment and Simulation"
DESCRIPTION:Abstract\n \nThe emergence of coordinated cellular\, tissue\, and organismal responses rely on complex biological networks. While the connectivity of the networks is increasingly defined\, understanding the dynamics of the system and the emergence of coordinated responses at multiple spatial and temporal scales is an unsolved problem in many systems. This is a challenge addressed by all living systems that utilize highly conserved chemical reaction networks that coordinate single cell behavior into tissues and into organisms.  To study the coordination\, we rely on the back and forth between simulation and experiments.  Specifically\, we developed and applied integrative simulations reaction-advection-diffusion partial differential equation models to discern the mechanism of Bone Morphogenetic Protein (BMP) signaling along the dorsal/ventral (DV) axis in zebrafish embryos\, and in the mouse developing organ or Corti.  In each of these systems\, gradients of BMP signaling form through the interplay of BMP ligands interacting with other secreted factors that shape the gradient.  We developed methods to quantify inputs and outputs of BMP signaling activity\, developed AI tools to segment every cell in a developing embryo\, and used the data to build and test mathematical models of different biological hypotheses of gradient formation and differentiation.  In zebrafish embryonic development\, we found that a source-sink mechanism is most consistent with formation of the ventral-to-dorsal gradient of BMP signaling; and in the developing organ of Corti in mouse\, we found that the BMP gradient forms an information-maximizing linear profile sufficient for multiple boundary specification along the developing organ.  These systems highlight how the back and forth between experiment and simulation drives an integrative understanding of developmental systems.

DESCRIPTION:Magnetic Resonance Imaging (MRI) can be accelerated by sampling below the Shannon-Nyquist rate via compressed sensing techniques. In this talk\, I will consider the problem of optimizing the under-sampling pattern in a data-driven fashion\, which has been an open problem for over a decade. For a given sparsity constraint\, our method optimizes the under-sampling pattern and reconstruction model\, using a computationally efficient end-to-end deep-learning strategy. We call our method Learning-based Optimization of the Under-sampling PattErn\, or LOUPE. Our experiments with brain and knee MRI scans show that the LOUPE-derived pattern can yield significantly more accurate reconstructions compared to standard under-sampling schemes. I will also present results for prospectively collected in-vivo images that demonstrate the practical utility of LOUPE in speeding up MRI scans.

SUMMARY:SIG Seminar:"Computational Design for the Next Manufacturing Revolution"
DESCRIPTION:Abstract: 3D printers are radically transforming the aerospace and automotive industries. Whole-garment knitting machines allow the automated production of complex apparel and shoes. Manufacturing electronics on flexible substrates enable a new range of integrated products for consumer electronics and medical diagnostics. These advances demonstrate the potential for a new economy of on-demand production of objects of unprecedented complexity and functionality. In my talk\, I argue that the field of computational design is essential for the next revolution in manufacturing. To build increasingly functional\, complex and integrated products\,  we need to create design tools that allow their users to efficiently explore high-dimensional design spaces by optimizing over a set of performance objectives that can be measured only by expensive computations.

SUMMARY:CBE PhD Dissertation Defense | Polymer Mechanics and Dynamics in Polymer Nanoparticle Composites
DESCRIPTION:Abstract:  \n“Polymer nanoparticle composites (PNCs) have become an important topic of research due to their highly tunable macroscopic properties. Compared to the pure polymers\, PNCs exhibit increase in mechanical strength\, altered thermodynamic properties\, and simultaneous improvement in permeability and selectivity in small molecule transport. Understanding the fundamental physics that control the behavior of both components in the PNCs can provide insights to the material design. In PNCs\, the microscopic variations often dominate the behavior at the macroscopic level. Previous research has shown significant deviations in both polymer conformation and dynamics near the nanoparticle (NP) surfaces from bulk polymers. However\, the heterogeneous nature of the PNCs makes understanding microscopic details using macroscopic experiments a difficult task. Therefore\, computational methods have been employed to investigate the polymer conformation\, mechanics\, and dynamics at the molecular level. In this dissertation\, I use PNCs with two levels of NP loading to investigate the origins of the various changes in properties. First\, I use molecular dynamics (MD) simulations to examine a class of PNCs with ultra-high NP loading\, in which the volume fraction of NPs is near the random-close-pack limit ( >50% ). This class of PNCs can be produced with either partial or complete filling of polymers. In these PNCs\, the polymer chains are highly confined due to the large number of NP surfaces\, thus are drastically altered in their conformation and dynamics. The second PNC system studied in this dissertation has a dilute amount of well-dispersed NPs to avoid NP-NP interaction and polymer confinement. In this case\, I use both MD simulations and classical density functional theory (cDFT) for fluids to understand the role of NP-polymer interactions\, solid curvature\, and polymer molecular weight.”

SUMMARY:MEAM Seminar: "Merging Human-Machine Intelligence with Soft Materials Technology"
DESCRIPTION:Whereas human tissues and organs are mostly soft\, wet and bioactive; machines are commonly hard\, dry and biologically inert. Merging humans\, machines and their intelligence is of imminent importance in addressing grand societal challenges in health\, sustainability\, security\, education and joy of living. However\, interfacing humans and machines is extremely challenging due to their fundamentally contradictory properties. At MIT Zhao Lab\, we exploit soft materials technology to form long-term\, high-efficacy\, multi-modal interfaces and convergence between humans and machines. In this talk\, I will first discuss the mechanics and general principles to design extreme properties including tough\, resilient\, adhesive\, strong\, fatigue-resistant and conductive for soft materials. Then I will discuss a set of soft materials technology platforms\, including i). bioadhesives for instant strong adhesion of diverse wet dynamic tissues and machines; ii). bioelectronics for long-term multi-modal neural interfaces; iii). biorobots for teleoperated and autonomous navigations and operations in previously inaccessible lesions such as in cerebral and coronary arteries. I will conclude the talk with a perspective on future human-machine convergence enabled by soft materials technology.

SUMMARY:ESE Grace Hopper Lecture: "Scalable Photonics: An Optimized Approach"
DESCRIPTION:Classical and quantum photonics with superior properties can be implemented in a variety of old (silicon\, silicon nitride) and new (silicon carbide\, diamond) photonic materials by combining state of the art optimization and machine learning techniques (photonics inverse design) with new fabrication approaches. In addition to making photonics more robust to errors in fabrication and temperature\, more compact\, and more efficient\, this approach is also crucial for enabling new photonics applications\, such as on-chip laser-driven particle accelerators\, and semiconductor quantum simulators.

SUMMARY:CIS Seminar:"Critical Computing Education
DESCRIPTION:Computing can be a wondrous\, powerful tool\, bringing us information\, experiences\, and connections that transform our lives for the better. However\, as many of us have learned\, computing has also contributed to great injustices\, increasing surveillance of our most vulnerable populations\, eroding the middle class through economic displacement\, and amplifying historical injustices embedded in society. In this talk\, I discuss our responsibility as scholars to engage both the powers and perils of computing in our research\, teaching\, and service. I specifically focus on three sources of injustice that are missing from computing literacy: the limits of computing\, the limits of data\, and the responsibility of computing professionals to center these limits in their work. Throughout\, I highlight recent discoveries from my lab as examples for how to engage these topics through research\, and end with ideas for how the audience can engage in their own research\, teaching\, and service.

SUMMARY:CBE Seminar: "The Role of Utilization in Meeting Mid-Century Carbon Removal Targets"
DESCRIPTION:Abstract \nThe utilization of CO2 broadly applies to any process that transforms captured CO2 into valuable products. These processes strive to achieve any of the following objectives: (1) permanent storage (2) revenue generation and/or (3) avoiding emissions of conventional products with high amounts of embodied carbon. This talk will explore how carbon utilization can be leveraged to help us meet the ambitious gigatonne-scale removal targets proposed by many agencies as necessary to combat climate change by mid-century. Topics covered will include the importance of CO2 source\, temporal aspects of storage\, the role of stock vs flux\, scaling limitations\, economic potential and risk. The significance and mutual dependency of these factors will be illustrated in regional merit-order modeling\, as well as select case studies on lifecycle emission assessments. These results inform policymakers\, investors and scientists on both the strengths and shortcomings of CCUS as a climate mitigation strategy.

SUMMARY:MSE Seminar: "Nano-Volumetric Materials Properties of Ferroelectrics and Photovoltaics via Tomographic AFM"
DESCRIPTION:Nano- and meso- scale materials properties are crucial to the macroscopic performance of a wide range of functional and photovoltaic devices. In 2-dimensions\, photoconductivity\, ferroelectricity\, and even domain dynamics have thus been investigated for decades now especially using variations of Atomic Force Microscopy. Our work and others reveals how these properties are frequently mediated by strain\, orientation\, grain boundaries\, and other microstructural defects or heterogeneities. However\, practical devices are often sensitive to\, or even controlled by\, sub-surface effects or thickness dependencies related to microstructure and concentration\, polarization\, and/or field gradients. Therefore\, we are advancing Tomographic AFM for volumetric materials property mapping\, with voxels of properties on the order of ~10 nm3. With polycrystalline photovoltaics such as MAPbI3 and CdTe\, TAFM literally uncovers new pathways to improve carrier separation via inter- and intra- granular defects (Luria\, Nature Energy\, 2017; Song\, Nature Communications\, 2020). For BiFeO3\, Tomographic AFM confirms Kay-Dunn thickness scaling\, LGD behavior with a minimum switchable thickness of <5 nm\, and even co-located domain and current maps which together directly reveal sub-surface topological defects (Steffes\, PNAS\, 2018). Such volumetric insight is increasingly important for engineering optimal performance and reliability of real-world\, 3-Dimensional materials devices.

SUMMARY:MEAM Seminar: "How to Make Your Ocean Smarter"
DESCRIPTION:Our oceans drive worldwide weather-climate systems; our rivers serve as nutrient conduits; and our marine ecosystems house the largest repository of biodiversity and mineral resources on the planet. Humans have relied on rivers\, lakes\, and oceans for transportation\, energy generation\, farming\, and recreation throughout our history. And today\, robots are critical tools in our stewardship of these resources. However\, there are significant autonomy challenges when working in dynamic and uncertain environments like oceans and rivers. Robot dynamics are tightly coupled to those of the environment\, while communication and localization are limited. \nControl under these conditions can be exacting\, but environmental dynamics may be harnessed to plan energy efficient paths and to maintain network connectivity. Networked robot teams can collect data to construct high fidelity models of the environmental dynamics which can be integrated into robot control and planning. Those same models can be used to guide robot control and sampling strategies to increase their predictive power. In this talk\, I will present our vision of a smart ocean observational framework to improve forecasting of weather-climate systems\, mitigation of contaminant dispersions\, and coordination of maritime search and rescue and humanitarian efforts.
