SUMMARY:CBE Seminar Series: "A New Phase of Biological Controls: A Design Framework for Programmable Synthetic Biomolecular Condensates and the Mechanisms of a Functional Liquid-Liquid Interface" (Yifan Dai\, Duke University)
DESCRIPTION:Abstract: \nA fundamental question in nature is how the cellular processes are organized with sequential and spatial precision in a dynamic and densely packed environment. Evidence is now mounting that biomolecular condensation\, a demixing process mediated by phase separation coupled with percolation\, dictates the organization principles of cellular biochemistry. From the perspective of synthetic biology\, programmable condensation in living cells represents a new fundamental capability for biological design\, going beyond the current engineering capability of lock-and-key interactions. In the first part of the talk\, I will introduce a rational design strategy of synthetic intrinsically disordered proteins toward functional synthetic biomolecular condensates for cellular controls in bacteria and human cells. I will demonstrate the applications of synthetic condensates on four distinct cellular processes: cell division\, transcription\, translation\, and modulation of protein circuits\, providing a toolbox for orthogonal central dogma. \nIn the second part of the talk\, I will dig into the physical chemistry principles of condensate microenvironments\, by which condensates can encode unique electrochemical features at its liquid-liquid interface. I will introduce a theoretical framework we developed for condensate interface\, which allows us to understand the density transition process of condensate formation from the perspective of electrochemistry. I will then discuss our experimental discoveries on the fundamental electrochemical properties of liquid-liquid interface and how these features can regulate cellular processes. These discoveries open new directions of condensate research and provide answers for many previously unexplained biological activities of biomolecular condensates. \nOverall\, the first work has established a design principle for programmable condensation as a new capability of synthetic biology. The second work combining insights from physical chemistry\, electrochemistry and cell biology has delivered a new paradigm for understanding how condensates can engender cellular functions through its chemical environments and liquid-liquid interface. \nBio: \nYifan Dai is a postdoc associate at the Department of Biomedical Engineering at Duke University\, co-advised by Professor Ashutosh Chilkoti and Professor Lingchong You. He obtained his B.S. and Ph.D. in 2017 and 2020 both in Chemical and Biomolecular Engineering from Case Western Reserve University. Since his undergraduate\, he had worked on engineering strategies to integrate synthetic biology with electrochemistry to enable translation of biological signals into electricity for biosensing applications\, which have led to multiple licensed technologies. In his postdoc\, he has worked on 1) uncovering the principles of biomolecular phase transitions for engineering biology and 2) establishing the theoretical framework of condensate microenvironments and liquid-liquid interface.

SUMMARY:CIS Seminar: "Methods of Data Lookup with Hashing"
DESCRIPTION:We will discuss methods of data lookup\, with a focus on hash sets / tables\, including motivation\, properties\, and variants. This will be in the context of a “CS 2” or data structures course. We will assume a basic familiarity with programming and comfort with implementing resizable lists; as well as knowledge of (but not necessarily comfort with) asymptotic analysis.

SUMMARY:ASSET Seminar: Decision-Aware Learning for Global Health Supply Chains\, Osbert Bastani (University of Pennsylvania)
DESCRIPTION:Abstract: \nMachine learning algorithms are increasingly used in conjunction with optimization to guide decision making. A key challenge is aligning the machine learning loss with the decision-making loss. Existing solutions have limited flexibility and/or scale poorly to large datasets. We propose a principled decision-aware learning algorithm that uses a Taylor expansion of the optimal decision loss to derive the machine learning loss. Importantly\, our approach only requires a simple re-weighting of the training data\, allowing it to easily and scalably be incorporated into complex modern data science pipelines while producing sizable efficiency gains. We apply our framework to optimize the distribution of essential medicines in Sierra Leone in collaboration with their National Medical Supplies Agency. Out-of-sample results demonstrate that our end-to-end approach significantly reduces unmet demand across 1000+ health facilities throughout Sierra Leone.

SUMMARY:CIS Seminar: "Rethinking System Design for Expressive Cryptography"
DESCRIPTION:Expressive cryptography\, including Secure Multi-Party Computation (SMPC) and Fully Homomorphic Encryption (FHE)\, has the potential to enable transformative new applications\, drawing significant interest from industry. Unfortunately\, it is often slow and resource-intensive\, making those applications difficult to realize. For example\, SMPC enables multiple organizations (e.g.\, hospitals) to run joint computations on their data (e.g.\, for better medical diagnosis and treatment) while keeping the inputs to the computation (e.g.\, patient data) secret. But SMPC can have high memory overhead\, making it difficult to scale such applications to large problem sizes. \nThis talk demonstrates how we can design and build systems to enable expressive cryptography to reach its full transformative potential. For example\, my system MAGE provides virtual memory for SMPC and FHE at nearly zero cost\, allowing them to efficiently scale beyond the system’s available memory. My work in this area also includes JEDI\, which shows how IoT devices can use expressive cryptography efficiently\, and TCPlp\, which was recently adopted in OpenThread\, an open-source network stack used in the smart home industry. By rethinking system design for expressive cryptography\, we can bring stronger security to existing applications and enable exciting new ones.

SUMMARY:MEAM Seminar: "Data-Aware Computational Models for Science and Engineering"
DESCRIPTION:In the past half-century\, partial differential equation (PDE)-based computational models have emerged as indispensable for science and engineering. However\, remarkable gaps still exist between state-of-the-art simulations and reality\, meaning that many simulations are ineffective in supporting decision-making or design under uncertainty for complex systems (e.g.\, Mars landing). To bridge the gap and fulfill challenging real-world missions\, I develop data-aware computational models that combine increasingly available data with complex PDE-based models to make improved predictions\, together with measures of their uncertainty. \nIn this talk\, I will focus on two complementary approaches to data-aware computational modeling. First\, I will discuss a new Bayesian method for updating/improving computational models and quantifying uncertainties based on measured data: our Kalman inversion approach is built on Kalman filtering and empirically converges in O(10) iterations with O(10) ensemble evaluations per iteration\, enabling effective Bayesian calibration with very few model evaluations. Second\, I will introduce our geometry-aware Fourier neural operator (FNO)\, a deep learning surrogate model which maps a given design geometry to a predicted PDE solution state. We use the automatic differentiation tools of deep learning packages to efficiently compute gradients of the FNO approximation\, enabling real-time multiphysics engineering design optimization. These methods we developed have been successfully applied in complex applications ranging from Mars landing supersonic parachute\, bacteria-resistant catheter design\, the digital twin for airfoil damage detection\, and the Earth system model for climate science.

SUMMARY:PICS Colloquium: "Building and using virtual models of the tricuspid valve toward better understanding\, diagnosis\, and treatment of its diseases"
DESCRIPTION:Computer simulations have become critical elements of the medical device design and regulatory approval process. Naturally\, the predictability and therefore value of such simulations depends highly on their accuracy. Especially for the design of heart valve replacements and repair technologies computer simulations have become a critical tool. While much progress has been made in modeling the aortic valve and the mitral valve\, much less effort has been spent on modeling the tricuspid valve. The reasons are multi-fold\, but include the general neglect of the valve as well as the high complexity of the valve in comparison to the three other valves. In our most recent work\, we are beginning to fulfill this gap. Specifically\, our objective is to develop\, validate\, and then publicly provide a truly subject-specific\, shared model of the human tricuspid valve. To this end\, we combine multi imaging-modality based measurements in beating human hearts that have been prepared in an organ preservation system\, with in-vitro measurements of heart valve geometric\, structural\, and mechanical properties. Once built\, we conduct finite element simulations with this valve and validate dynamic simulations throughout the cardiac cycle against in-situ measurements. Finally\, we show case our model by first mimicking a diseased valve\, which we then repair using a surgical and an interventional approach.

SUMMARY:Spring 2023 GRASP on Robotics: Rodney Brooks\, Robust.AI\, "Academic research: exploration vs exploitation"
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. This week’s presenter will be in-person as well.  \n  \nABSTRACT\nIntelligent action is critical in robotics\, more so than much of AI where results are often mediated by humans in the loop. That said\, robotics also needs to interact with humans. Currently we are in an age of exploitation of techniques that give new capabilities\, and this is as true in academia as it is in industry. But we should hope that a few people in academia are also exploring whether current techniques are the ultimate solutions for robotics\, or whether we should give some thought to whether we are busy riding a silicon-powered wave which will asymptote way below where popular hypenotism would lead us to expect. Perhaps there are really different questions to ask; looking at biological systems suggests that perhaps we don’t yet have a good grasp of very fundamental possibilities\, and that there are rich rewards (and also possible penury) for those willing to take a hard look.

SUMMARY:CIS Seminar: "Software Security Challenges in the Era of Modern Hardware"
DESCRIPTION:Today’s hardware cannot keep secrets. Indeed\, the past two decades have seen the discovery of a slew of attacks where an adversary exploits hardware features to leak software’s sensitive data. These attacks have shaken the foundations of computer security and caused a major disruption in the software industry. Fortunately\, there has been a saving grace\, namely the widespread adoption of models that have enabled developers to build secure software while comprehensively preventing hardware vulnerabilities. \nIn this talk\, I will present two new classes of vulnerabilities that fundamentally undermine these prevailing models for building secure software. In the first part\, I will demonstrate that the current constant-time programming model is insufficient to guarantee constant-time execution. In the second part\, I will demonstrate that the current resource partitioning model is insufficient to guarantee software isolation. Finally\, I will provide an overview of my future research plans for enabling the design of more secure software and hardware systems.

SUMMARY:BE Seminar: "Probing Metabolism Across Scales" (Yihui Shen\, Princeton University)
DESCRIPTION:Metabolism supports the biosynthetic and energetic demand of all living creatures. Over decades\, we have accumulated knowledge of how individual enzymes work in vitro\, but we don’t have a good sense about how they work together in vivo. Thus\, fundamental to our understanding of metabolic operation is the ability to measure metabolic activity in vivo. In this talk I will first briefly introduce an optical imaging technique that allows visualization of metabolism at micron scale. And then I will show how we use multi omics to probe metabolism at a systems scale. By quantifying hundreds of molecular components\, these systems-level measurements allow us to gain fundamental metabolic design principles. For example\, an important metabolic decision is whether to generate energy through fermentation or respiration. Respiration is much more energy efficient. Nevertheless\, many fast-growing cells\, including the baker’s yeast\, activated T cells\, and tumor cells\, switch to aerobic glycolysis (fermentation in the presence of oxygen). How do they achieve the metabolic switch? Why would they prefer wasteful metabolism?  I hope you will join the journey with me to explore the plasticity of metabolism.

SUMMARY:ESE Spring Seminar - "Reliable Data-Driven Decision-Making Systems"
DESCRIPTION:Despite impressive success in domains such as vision and language\, machine learning is still far from reliable integration into many challenging real-world scenarios\, such as healthcare\, where the coverage of existing data and the ability to collect new\, diverse data are limited. This talk focuses on mathematically formulating and addressing some of the challenges in data-driven decision-making systems\, studied in the reinforcement learning (RL) framework. I will discuss decision-making based on two sources of data: historical (offline) data and actively-collected data. In learning from offline data\, I first mathematically formulate the challenge of partial data coverage. I show that this formulation combined with pessimistic offline RL unifies the major offline learning paradigms: imitation learning and conventional offline RL. I then present statistically-optimal and practical offline RL algorithms that simultaneously exploit expressive models\, such as deep neural networks\, and historical datasets with any coverage\, to learn good decision-making policies. In learning from interactive data\, I present general formulations and theoretically-guaranteed algorithms that exploit problem structure and expressive models to collect data for learning good policies\, with efficacy demonstrated in a variety of navigation and locomotion tasks.

SUMMARY:Spring 2023 GRASP SFI: Melkior Ornik\, University of Illinois Urbana-Champaign\, "System Resilience and Guaranteed Performance in the Face of Unexpected Adversity"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. This week’s presenter will be in-person as well. \nABSTRACT\nThe ability of a system to correctly respond to a sudden adverse event is critical for high-level autonomy in complex\, changing\, or remote environments. By assuming continuing structural knowledge about the system\, classical methods of adaptive or robust control largely attempt to design control laws which enable the system to complete its original task even after an adverse event. However\, catastrophic events such as physical system damage may render the original task impossible to complete. In other words\, any control law that attempts to complete the task is doomed to be unsuccessful. Instead\, an autonomous planner should recognize the task as impossible to complete\, propose an alternative that can certifiably be completed given the current knowledge\, and formulate a control law that drives the system to complete this new task. To do so\, in this talk I will present the emergent twin framework of guaranteed performance and resilience. Combining methods of optimal control\, online learning\, and reachability analysis\, these frameworks first compute a set of temporal tasks completable under all system dynamics consistent with the planner’s partial knowledge. These tasks can then be pursued by online learning and adaptation methods. The talk will consider three scenarios: actuator degradation\, loss of control authority\, and structural change in system dynamics\, and will briefly present several applications to aerial and maritime vehicles\, as well as infrastructure design. Finally\, I will identify promising future directions of research\, including real-time safety-assured mission planning\, resilience of complex networks\, and perception-based task assignment.

SUMMARY:Spring 2023 GRASP Seminar: Henry Fuchs\, UNC Chapel Hill\, "Augmented Reality Glasses: a 50-year Adventure"
DESCRIPTION:This is an in-person only event with attendance in Raisler Lounge (Towne 225).

That future may not arrive for a while and predicting its benefits and problems may be as premature as early predictions about the use of mobile phones or about “a helicopter in every garage.” Nevertheless\, a few sample applications seem both obvious and promising\, 1) continuous physiological monitoring for sudden and long-term health changes\, and 2) virtually embodied avatars for guidance in navigation\, exercise\, and training. I will also talk about the rocky history of head-worn AR systems\, which in contrast to the amazing\, continuous advances in Integrated Circuit fabrication technology\, has gone through multiple bust and boom cycles. I will talk about a few of the historic obstacles and how some were overcome and others side-stepped. I will summarize a few of the remaining problems\, possible paths to their solution\, and describe several of our projects in these areas.

SUMMARY:MEAM Seminar: "Designing Interfacial Phenomena for Water\, Energy\, and Sustainability"
DESCRIPTION:Solid/water interfacial phenomena are pervasive in both natural and built environments. Heat exchangers\, membrane pores\, and packed bed reactors are all examples of solid/water interfaces where interfacial phenomena and small-scale fluid physics can have outsized influences on process efficacy and sustainability. Even innocuous surfaces such as reactor walls are not inert and can actively interact with aqueous solutions and thereby create inefficiencies. Surface properties are crucial in controlling and reducing such inefficiencies. New tools and techniques in the fields of micro/nano-fabrication\, thin film deposition\, and soft matter physics have enabled unprecedented capability to manufacture engineered interfaces. By precisely designing the composition\, chemistry\, and microscopic geometry of interfaces\, it is possible to go beyond simply selecting the best available material for a given application. Instead\, we can specifically design surfaces and processes for fine-tuned control over interfacial phenomena to achieve drastic reduction\, or even complete elimination\, of inefficiencies. Here\, three examples in which interfacial engineering can enable new paradigms for water\, energy\, and sustainability will be presented. I will show that composite liquid/solid surface can eliminate mineral fouling for improved material resilience\, that nano-engineered materials can induce ejection of foulant crystals with potential application for heat transfer and waste brine management\, and that multiphase microfluidics with controlled pore geometries can enable new separation processes.

SUMMARY:CIS Seminar: "Proofs\, Cryptography and Quantum Information"
DESCRIPTION:Many cryptographic protocols will be rendered insecure if sufficiently powerful quantum computers are built. While this remains at least a few decades away\, there is another\, more immediate\, problem: many widely-used security analysis techniques rely on properties of classical information that do not hold in the quantum setting\, rendering the security of many schemes unclear even against today’s quantum computers. In this talk I will present techniques I have developed to address both of these challenges.

SUMMARY:MSE Seminar: "Metamaterials: From Invisibility Cloak to Future Extended Reality Displays"
DESCRIPTION:The invisibility cloak in Harry Potter and the dreams of invisibility as a superpower are no longer fiction. With the invention of metamaterials\, they are theoretically and experimentally possible in real life. Metamaterials — materials that are engineered to have properties that are not found in naturally-occuring materials — allow us to overcome physical limitations. Scientists around the world are researching metamaterials that can be used in diverse sectors\, including healthcare\, optical display\, and military affairs. For example\, metalenses\, which can exceed the physical limitations of light\, may facilitate leaps in biology and chemistry. The development of metamaterials has just begun\, but their potential is limitless. In this talk\, I will give a brief overview of metamaterials and metasurfaces: principles\, applications and manufacturing methods towards their science-to-technology transition.

SUMMARY:ASSET Seminar: The marriage of logic and learning: will it be a happily ever after?\, Jyotirmoy Deshmukh (University of Southern California)
DESCRIPTION:Presentation Abstract: \nHuge strides have made in the widespread adoption of autonomous and human-in-the-loop cyber-physical systems (CPS)\, partly fueled by dramatic improvements in learning-based techniques. An important aspect of such CPS applications is that they are safety-critical: any undesirable behavior by such systems can cause serious harm to human lives or property. The formal methods community has been an advocate of using logic and automata as specifications for safety-critical CPSs\, and the past few decades have seen significant strides in algorithms for their verification\, testing\, and automated synthesis. A new challenge now is the presence of learning-enabled components (LECs) in CPSs\, and in this talk\, we will review some recent work on using logic and learning-based techniques to provide guarantees for CPS applications using LECs. The happiness of this marriage between logic and learning depends on the applicability and scalability of these techniques to real-world systems; we will discuss success stories as well as challenges that need to be solved.

SUMMARY:MEAM Seminar: "3D Printing Active Electronic Devices"
DESCRIPTION:The ability to three-dimensionally pattern semiconducting electronic and optoelectronic materials could provide a transformative approach to creating active electronic devices without the need for a cleanroom or conventional microfabrication facilities. This could enable the generation of active electronics on-the-fly\, using only source inks and a portable 3D printer to realize electronics anywhere\, anytime\, including directly on the body. Indeed\, interfacing active devices with biology in 3D could impact a variety of fields\, including biomedical devices\, wearable electronics\, bioelectronics\, smart prosthetics\, and human-machine interfaces. Developing the ability to 3D print various classes of materials possessing distinct properties will enable the freeform generation of active electronics in unique functional\, interwoven architectures. Yet\, achieving seamless integration of these diverse materials via 3D printing is a significant challenge which requires overcoming discrepancies in material properties in addition to ensuring that all the materials are compatible with the 3D printing process. We will present a strategy for three-dimensionally integrating diverse classes of materials using a custom-built 3D printer to create fully 3D printed device components built around active electronics. As proof of concept\, we have 3D printed quantum dot-based light-emitting diodes (QD-LEDs)\, polymer-based photodiodes on curvilinear surfaces\, flexible displays\, and skin-interfaced hybrid devices. These results represent a series of critical steps toward the 3D printing of high performance\, active electronic materials and devices.

SUMMARY:PICS Seminar: "Computational fluid dynamics for slurry rheology in flow battery and underlying drag-reduction mechanisms in turbulent flow control"
DESCRIPTION:Email jnespos@seas.upenn.edu for the Zoom link. \nThis talk will start by introducing diverse fluid-mechanics research conducted in the Park research group\, including complex fluids\, electrokinetics\, biofluids\, transition-to-turbulence\, and turbulent flow. I will then focus on two projects at very different flow regimes. For both projects\, the modeling\, analysis\, and computation will be presented along with their engineering applications. The first project is dedicated to a creeping flow or Stokes flow\, where dynamics and rheology of highly conductive particle suspensions in an electric field are investigated to help design flow battery slurries. Notably\, the negative particle pressure is found to arise at high concentrations\, which could be considered a first-of-its-kind in such particle systems. The second project is dedicated to a high-speed flow or turbulent flow\, where three flow-control methods are investigated to elucidate their underlying drag-reduction mechanisms. These methods include imposing an external body force\, adding long-chain polymers\, and utilizing slip surfaces. A temporal analysis based on high- and low-drag periods is employed\, showing that the polymer and slip methods exhibit a similar mechanism\, while the body force method is different. I will conclude by providing the implications of these different drag-reduction mechanisms.

SUMMARY:MSE Seminar: "Bio-inspired Design\, Mechanics\, and Manufacturing of Architected Cementitious Materials"
DESCRIPTION:Dr. Moini’s research is focused on bio-inspired design and development of architected materials using novel additive manufacturing processes and automated robotic technologies for applications in civil and energy infrastructure. His work is motivated by the intellectual challenge of understanding the mechanics of intrinsically brittle engineering materials and the development of ductile and flaw-tolerant responses using biomimetic design principles and new material assemblies. Such materials can provide advanced functionality and damage-tolerant behaviors and allow for asking interesting questions about the interplay between desired materials properties such as toughness and strength. Dr. Moini’s other areas of research include integrated multi-component autonomous manufacturing\, early-age deformations of colloidal materials in additive processes\, packing and solidification of particulate systems\, and applying interior tomography techniques to understand the processing-structure-function relationships in architected and additively manufactured brittle ceramic and cement-based materials.

SUMMARY:CBE/BE Seminar: "Targeting Sugars for Immunotherapy in Cancer and Beyond" (Jessica Stark\, Stanford)
DESCRIPTION:Co-hosted by the Departments of Chemical and Biomolecular Engineering & Bioengineering. \nNew paradigms to harness the immune system are urgently needed to address unmet needs in human health. I am working to understand and engineer glycoimmunology – the roles of sugars\, or glycans\, in the immune system – to bridge this gap. During my PhD\, I developed a platform called iVAX for rapid and portable production of conjugate vaccines\, a class of FDA-approved vaccines that use glycans to elicit antibacterial immunity. I showed that iVAXderived conjugate vaccines protected mice against lethal pathogen challenge. My iVAX approach has the potential to accelerate development and distribution of vaccines to address emerging drug-resistant bacteria. As a postdoctoral fellow\, I designed antibody-lectin (AbLec) chimeras to target glycans that act as immune checkpoints in cancer. I showed that AbLecs potentiated tumor killing by binding and blocking tumor-associated glycans that otherwise inhibit anti-cancer immune responses. AbLecs represent a new modality of cancer immunotherapy that promises to increase the fraction of patients who benefit from treatment. My independent group will work to realize the full potential of glycoimmunology for human health\, by developing new immunotherapy modalities and uncovering new drug targets.While we will initially focus on fundamental questions and therapeutic applications in cancer\, in the long term we will apply our synergistic platform technologies to additional therapeutic contexts\, including autoimmunity\, infection\, and neurodegeneration.

SUMMARY:ASSET Seminar: What makes learning to control easy or hard?\, Nikolai Matni (University of Pennsylvania)
DESCRIPTION:Presentation Abstract: \nDesigning autonomous systems that are simultaneously high-performing\, adaptive\, and provably safe remains an open problem.  In this talk\, we will argue that in order to meet this goal\, new theoretical and algorithmic tools are needed that blend the stability\, robustness\, and safety guarantees of robust control with the flexibility\, adaptability\, and performance of machine and reinforcement learning.  We will highlight our progress towards developing such a theoretical foundation of robust learning for safe control in the context of two case studies: (i) characterizing fundamental limits of learning-enabled control\, and (ii) developing novel robust imitation learning algorithms with sample-complexity guarantees.  In both cases\, we will emphasize the interplay between robust learning\, robust control\, and robust stability and their consequences on the sample-complexity and generalizability of the resulting learning-based control algorithms.

SUMMARY:ESE Spring Seminar - "3D Functional Mesostructures: From Neural Interfaces to Environmental Monitors"
DESCRIPTION:Complex\, three dimensional (3D) micro/nanostructures in biology provide sophisticated\, essential functions in even the most basic forms of life. Compelling opportunities exist for analogous 3D structures in man-made devices\, but existing design options are highly constrained by comparatively primitive capabilities in fabrication and growth. Recent advances in mechanical engineering and materials science provide broad access to diverse\, highly engineered classes of 3D architectures\, with characteristic dimensions that range from nanometers to centimeters and areas that span square centimeters or more. The approach relies on geometric transformation of preformed two dimensional (2D) precursor micro/nanostructures and/or devices into extended 3D layouts by controlled processes of substrate-induced compressive buckling\, where the bonding configurations\, thickness distributions and other parameters control the final configurations. This talk reviews the key concepts and focuses on the most recent developments with example applications in areas ranging from mesoscale microfluidic/electronic networks as neural interfaces\, to bio-inspired colorimetric microfliers as environmental sensing platforms.
