SUMMARY:MSE Seminar : "Semiconducting Materials for Opto/Bioelectronic Applications;  Chemistry\, Processing and Device Engineering" Antonio Facchetti - Georgia Institute of Technology
DESCRIPTION:In this presentation we report the realization of novel semiconductor materials\, as well as thin-film processing and morphology engineering\, for flexible and stretchable organic electronic devices such as thin film transistors\, solar cells\, electrolyte gated transistors\, sensors and neuromorphic circuits. On material development\, we present “soft” small-molecules and polymers by co-polymerizing pi-deconjugated building blocks\, properly designed additives and tuned backbone conformation. New transistor architectures using semiconductor film porosity as the key element for enhancing mechanical flexibility and tune charge transport are also demonstrated. These films\, combined with pre-stretched elastomeric substrates\, enabling unprecedentedly stable current-output characteristic upon mechanical deformation\, which are used for sensing analytes\, strain\, light\, temperature and physiological parameters. Furthermore\, we report our recent work on the design of fluorinated acceptors for organic solar cells and a new route to achieve ultra-stretchable solar cell devices. Finally\, we report our recent work on molecular n-doping of organic semiconductors using a novel strategy involving catalysts.

SUMMARY:FOLDS seminar: Learning in Strategic Queuing
DESCRIPTION:Zoom link: https://upenn.zoom.us/j/98220304722 \n  \nOver the last two decades we have developed good understanding how to quantify the impact of strategic user behavior on outcomes in many games (including traffic routing and online auctions) and showed that the resulting bounds extend to repeated games assuming players use a form of learning (no-regret learning) to adapt to the environment. However\, these results assume that there is no carry-over effects between rounds: outcomes in one round have no effect on the game in the future. Many repeated games have an evolving state resulting in direct carry-over effect\, such as repeated auctions with budgets\, as well as queuing systems. In this talk we will study this phenomenon in the context of a game modeling queuing systems: routers compete for servers\, where packets that do not get served need to be resent\, resulting in a system where the number of packets at each round depends on the success of the routers in the previous rounds. We study the required excess server capacity needed to guarantee that all packets get served in two different queuing systems (with or without buffers) despite the selfish (myopic) behavior of the participants.

SUMMARY:ESE Ph.D. Thesis Defense: "Microfabricated devices for in-vivo sensing for mitochondrial assessment"
DESCRIPTION:Monitoring of oxygen concentration in biological tissues is essential for understanding cellular metabolism\, mitochondrial function\, and tissue regeneration. Mitochondrial dysfunction is linked to a wide range of metabolic and degenerative diseases\, yet current diagnostic approaches lack the capability to continuously measure oxygen and metabolite dynamics in vivo. This work introduces an implantable electrochemical sensor platform developed for real-time monitoring of tissue oxygen tension to support diagnosis and study of mitochondria-related disorders. The research encompasses device design\, fabrication\, preclinical validation\, and clinical testing within a translational framework. A complementary lactate sensor further extends the platform’s diagnostic capabilities\, establishing groundwork for future metabolic monitoring technologies.

SUMMARY:Fall 2025 GRASP on Robotics: Jan Peters\, Technische Universität Darmstadt & German Research Center for Artificial Intelligence\, "Inductive Biases for Robot Learning"
DESCRIPTION:This event will be in-person ONLY in Wu and Chen Auditorium. \nABSTRACT\nThe quest for intelligent robots capable of learning complex behaviors from limited data hinges critically on the design and integration of inductive biases—structured assumptions that guide learning and generalization. In this talk\, Jan Peters explores the foundational role of inductive biases in robot learning\, drawing from insights in control theory\, neuroscience\, and machine learning. He discusses how exploiting physical principles\, modular control structures\, symmetry\, temporal abstraction\, and domain-specific priors can drastically reduce sample complexity and improve robustness in robotic systems. \nThrough a series of concrete examples—including robot table tennis\, tactile manipulation\, quadruped locomotion\, and dynamic motor skill learning on anthropomorphic arms—Peters illustrates how inductive biases enable efficient policy search\, reinforcement learning\, and imitation learning. These applications demonstrate how embedding prior knowledge about motor primitives\, control hierarchies\, or contact dynamics helps robots acquire versatile skills with minimal data. The talk concludes with a vision for future robot learning systems that integrate such structured biases with modern data-driven methods\, enabling scalable\, adaptive\, and generalizable autonomy in real-world environments.

SUMMARY:MEAM Seminar: "Multiplying the Coolness of Gels: Messy Networks\, Double Networks\, and More"
DESCRIPTION:Many materials we eat\, spread\, squeeze\, or 3D print are gels\, soft amorphous solids whose solid component comprises self-assembled networks of particles\, fibers\, or agglomerates of proteins\, polymers\, and colloids. The space between and within human cells is permeated by self-assembled gel networks\, the extra-cellular matrix and the cytoskeleton\, whose self- organization and heterogeneity is central to biological functions. Self-assembled gels have adaptive\, tunable\, and nonlinear rheology determined by a complex interplay between the molecular cohesion and surface interactions\, the aggregation kinetics that drive formation of various types of structures\, and the effect of external forces that can promote breaking or reforming of the load-bearing backbone. Solidification processes are typically sources of frozen-in stresses and help build a memory of the processing history in these amorphous solids. Disorder and self-organization determine stress localization under load and the feedback between stress heterogeneities\, structural disorder\, and nonequilibrium conditions is therefore key to the mechanical response of these fascinating and ubiquitous materials.

SUMMARY:ESE Fall Seminar - "Developing Custom Portable Low-Field MRI for Point-of-Care Imaging"
DESCRIPTION:MRI remains the gold standard in neuroimaging\, but its high costs\, large footprint\, and infrastructure requirements limit deployment in many settings—including intensive care units (ICUs)\, emergency vehicles\, and neonatal intensive care units (NICUs). These challenges demand portable\, low-cost MRI systems specifically engineered for operation in space- and power-limited environments. Rather than adapting commercial scanners\, our work focuses on the engineering design and prototyping of custom low-field MRI systems\, using permanent magnets and compact hardware tailored to specific use cases. We hardware development with model-based reconstruction techniques to reduce system complexity and improve performance. This presentation will highlight several systems developed in our lab at the MGH Martinos Center—including a dedicated neonatal brain scanner—and will emphasize the technical and practical considerations involved in building accessible MRI from the ground up.

SUMMARY:Penn AI Presents: “How Brains and Machines Solve the Binding Problem”
DESCRIPTION:Despite decades of research\, we still do not know how the brain integrates the many features of an object into a coherent whole\, or whether artificial systems perform similar binding. In our first study\, we find that large self-supervised vision transformers spontaneously develop a low-dimensional “same-object” representation that predicts whether two image patches belong to the same object with over 90% accuracy. Removing this signal disrupts segmentation\, showing that object binding naturally emerges in deep networks trained on natural images. In our second study\, we develop a mechanistic model of attention and binding that captures core neurobiological phenomena such as selective focus and inhibition of return. Together\, these results suggest a shared computational principle: binding arises from structured interactions between distributed representations\, enabling both brains and machines to form coherent percepts from fragmented sensory data. \nRegister Now

SUMMARY:CIS Seminar: "Diffusion Generative Models for Non-Euclidean Data"
DESCRIPTION:As a major powerhorse for generative AI\, diffusion models have demonstrated great successes in Euclidean spaces\, such as for generating images and videos. This talk\, on the other hand\, will focus on a more nascent aspect\, namely non-Euclidean diffusion models. One can for example consider the generative modeling of data that are discrete\, living on manifold\, constrained\, or with multiple such modalities\, as they correspond to important applications\, some just emerging\, including (vision-) language model\, robotic motion planning\, molecular engineering\, and the design of quantum systems. After briefly introducing selected works of ours on these topics\, I will expand on one example\, where data live on a special type of manifolds known as Lie groups. Such a setting arises in the Gen-AI design of protein\, robotic planning\, and quantum problems. By leveraging and meshing variational optimization\, delicate interplays between continuous- and discrete-time dynamics\, and deep connections between optimization\, sampling and optimal transport\, I will turn our recent accelerated manifold optimization technique\, first into a sampler that is fast converging without requiring log-concavity condition or its common relaxations\, and then into an efficacious Lie group generative model. If time permits\, theoretical understandings of selected diffusion models will also be briefly discussed.

SUMMARY:MEAM Ph.D. Thesis Defense: "Mechanical Behavior and Fracture of Fibrous Materials at Large Deformations"
DESCRIPTION:The mechanical behavior of fiber network materials is characterized by large deformations before failure and a strain-stiffening stress-strain response. In this thesis\, this is investigated using discrete simulations at the microstructural level along with theoretical and computational results from continuum models. Cauchy and first Piola-Kirchhoff stress tensors for discrete networks of central-force elements are defined based on the equivalence of virtual power between the discrete system and its continuum representation. The framework is rigorously validated by demonstrating that non-uniform stress fields computed in discrete simulations of networks with defects and inhomogeneities show excellent agreement with continuum predictions for problems involving both infinitesimal and large\, non-linear deformations. Network materials are reported to resist fracture in the presence of cracks\, and this property is related to their nonlinear behavior. A computational model for the microstructure of network materials is developed to study the effects of a sharp crack under very large deformations. The computed stress field in the discrete network reproduces the asymptotic crack-tip fields based upon a continuum constitutive model derived from representative volume elements of the discrete network. The dominant stress components as a function of the undeformed distance from the crack follow a singular relation that is similar to the classical (small strain) HRR solution. The scaling exponent is determined completely by the constitutive behavior of individual fibers\, which directly relates the macroscopic behavior directly to the microstructure. Finally\, a continuum model that predicts macroscopic behavior for arbitrary states of deformation\, including damage evolution\, is constructed from mesoscopic simulations. The continuum model can access length- and time-scales that are inaccessible in a related class of high-fidelity discrete simulations\, which allows prediction of fracture toughness\, the material property that determines rupture resistance in the presence of defects.

SUMMARY:ASSET Seminar: "Testing AI's Implicit World Models"
DESCRIPTION:Many of the robustness properties that are required for real-world applications of AI would be realized by a model that has understood the world. But it is unclear how to measure understanding\, let alone how to define it. This talk will propose theoretically-grounded definitions and metrics that test for a model’s implicit understanding\, or its world model. We will focus on two kinds of settings: one where implicit world models are tested behaviorally\, and another that tests a model’s representation. These exercises demonstrate that models can make highly accurate predictions with incoherent world models\, revealing their fragility. \n  \nZoom: https://upenn.zoom.us/j/95189835192 \nPasscode: 797599

SUMMARY:Fall 2025 GRASP SFI: Wei Wang\, University of Wisconsin–Madison\, “Toward Advanced Autonomy in Complex Aquatic Environments”
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom.  \nABSTRACT\nMarine robots have undergone significant growth\, driven by recent advances in artificial intelligence\, sensing technologies\, and decision-making systems. As demands for ocean exploration\, exploitation\, and conservation continue to rise\, there is an increasing necessity for advanced autonomy in marine robots at both individual and group levels\, as well as for frequent and safe deployment of marine robots at an affordable cost. However\, the current marine robots available still fall short in meeting the demands of real-world applications\, facing challenges such as robust and safe control in complex environments\, self-localization and mapping of their environment\, and efficient sensing and coordination within a group. My long-term goal is enabling robots to perform tasks autonomously in challenging marine environments by developing innovative robots and advanced algorithms. In this talk\, I will highlight my research in three key areas: 1) learning-based control and navigation of 2D surface vehicles in urban waterways\, 2) design and coordination of 2D multi-robot systems on the water surface and 3) developing biologically inspired robots and sensors to address challenges faced by 3D underwater robots and robotic swarms. I will also briefly discuss open research problems on these topics.

SUMMARY:MSE PhD Thesis Defense: "Rheology and Clogging Study of Filamentous Suspensions: Bridging Microscopic Dynamics and Macroscopic Behaviors" 
DESCRIPTION:Suspensions of filamentous materials\, or filamentous suspensions\, represent a unique class of complex fluids in which the interplay between particle anisotropy and filament interactions – both intra- and inter-filament associations –gives rise to rich and tunable rheological behaviors. Such suspensions are ubiquitous across natural and engineered systems\, with their applications ranging from the locomotion of microorganisms and drag reduction in turbulent flows to fiber processing in papermaking and the development of functional nanomaterials. Their characteristics of a filamentous or fibrillar nature\, marked by a high aspect ratio particle structure and finite mechanical flexibility\, enable not only the formation of entangled networks in which mechanics and dynamics depend strongly on dimension\, concentration\, and surface chemistry\, but also bring greater complexity to material responses and flow phenomena. Despite their widespread utilization as colloidal materials\, understanding how filamentous suspensions are affected by interactions among molecular species and filaments under varying conditions (pH\, temperature\, ionic strength\, etc.)\, as well as mechanisms governing clogging\, remains limited. Such understanding is crucial for tailoring their properties and performance to meet the needs of specific applications\, such as rheology modification of complex fluids. To address these knowledge gaps\, two complementary studies—rheology and clogging—are performed independently at the microscopic and macroscopic scales\, respectively\, to elucidate how the filamentous structure and associated physical properties manifest across multiple length scales. First\, we systematically investigate the rheology of cellulose nanofibril (CNF) suspensions in the presence of salts and polymers to probe microscopic mechanisms arising from fibril-fibril\, fibril-salt\, and fibril-polymer interactions. Our studies reveal how ion–colloid and polymer–colloid interactions dictate the formation\, structure\, and dynamic response of CNF networks\, providing a framework for enhanced CNF-containing complex fluid formulations. Secondly\, we examine the clogging behavior of suspensions of threadlike colloids to uncover the macroscopic mechanisms underlying collective dynamics in these granular systems. Analysis of clogging probability and flow conditions provides insight into the transition between flow and jammed (clogged) states. Together\, these investigations establish a deeper understanding of how anisotropic filamentous geometry and its corresponding interactions govern complex rheological and flow-arrest behaviors\, thereby guiding the design of advanced materials and the optimization of processing for filament-based materials.

SUMMARY:MSE Seminar: "Building Cyberinfrastructure for Advancing Laboratories of the Future"
DESCRIPTION:The development of automated experimental facilities and the growing trend of experimental data digitization brought enormous opportunities for radically advancing laboratories. As many laboratory research tasks involve predicting and understanding previously unknown physical or chemical relationships\, the availability of experimental data enables machine learning (ML) approaches to substantially accelerate the conventional design-build-test-learn process. In this talk\, we will introduce software packages\, including RobustGaSP\, RobustCalibration\, FastGaSP\, DDM-UQ\, and AIUQ\, for constructing scalable surrogate models to predict complex relationships\, enabling efficient inverse estimation and materials characterization. Furthermore\, we introduce how artificial intelligence (AI) agents based on large language models can help researchers learn background knowledge in materials science and data science to accelerate discovery processes. We will introduce various case studies enabled by these tools\, including universal phase identification of block copolymers by small-angle X-ray scattering\, ab initio uncertainty quantification in scattering analysis of microscopy\, fast phase prediction of charged polymer blends by white-box machine learning surrogates\, and reliable emulation of classical functional theory calculation by active learning with error control.

SUMMARY:FOLDS seminar: Function Space Perspectives on Neural Networks
DESCRIPTION:Zoom link: https://upenn.zoom.us/j/98220304722 \n  \nThis talk reviews a theory of the functions learned by neural networks with Rectified Linear Unit (ReLU) activations. At its core is the observation that deep ReLU networks can be characterized as solutions to data-fitting problems in certain infinite dimensional function spaces. The solutions are compositions of functions from Banach spaces of second-order bounded variation\, defined in the Radon transform domain. Functions in these spaces exhibit strong smoothness in most directions\, making it a natural setting for adapting to intrinsic low-dimensional structure in data. Moreover\, the norms in these spaces are closely tied to the size of neural network weights\, providing a direct connection between function complexity and network parametrization. In particular\, the total variation norm provides an analytic tool for identifying functions that cannot be realized by shallow networks\, thereby yielding a precise characterization of depth separation. Representer theorems reveal the solutions are sparse in the number of active neurons per layer. Sparsity provides a principled path to network compression\, yet some sparse solutions can suffer from poor generalization. The theory suggests new training strategies to promote solutions that generalize more robustly.

SUMMARY:MEAM Ph.D. Thesis Defense: "Exploring Self-Assembly of 2D Materials: Insights from Graphene Auto-Kirigami"
DESCRIPTION:In nature\, thin sheets bend\, fold\, and curve to create functional three-dimensional forms—from insect wings to leaves and flower petals. Over the past decades\, such behavior has inspired engineered systems ranging from soft robotics to deployable electronics. Extending these ideas to atomically thin two-dimensional (2D) materials such as graphene opens new opportunities: these materials can transform into structures that extend beyond flat geometry through self-driven processes. Graphene\, for example\, can spontaneously assemble into self-stacked structures through self-folding\, self-tearing\, and nearly frictionless self-propagation\, all driven by interfacial energy. We introduce the term auto-kirigami (AK) to describe these self-folded and self-propagating structures\, in analogy to kirigami—the cutting and folding of thin sheets to create complex morphologies\, highlighting the spontaneous nature of this process. \nAK represents a unique form of self-assembly in 2D materials with implications spanning function\, fabrication\, and fundamental understanding. Yet\, key questions remain regarding how AK initiates and grows\, and how it varies across material systems. In particular\, the mechanisms that control its onset\, directionality\, and resulting morphology remain unresolved. In this talk\, I will present a comprehensive investigation of AK formation that integrates experiments\, continuum modeling\, and molecular dynamics simulations. I will show how tip-induced shear in graphene enables reproducible AK formation\, how lattice-level anisotropies govern its directional growth and geometry\, and how atomistic simulations reveal the initiation pathways inaccessible to experiments. These results provide a unified understanding of AK as a self-driven phenomenon and highlight its potential as a programmable route to reconfigurable nanoscale architecture.

SUMMARY:Fall 2025 GRASP on Robotics: Jie Tan\, Google DeepMind\, “Gemini Robotics: Bringing AI into the Physical World”
DESCRIPTION:This event will be in-person ONLY in Wu and Chen Auditorium. \nABSTRACT\nRecent advancements in large multimodal models have led to the emergence of remarkable generalist capabilities in digital domains\, yet their translation to physical agents such as robots remains a significant challenge. In this talk\, I will present Gemini Robotics\, an advanced Vision-Language-Action (VLA) generalist model capable of directly controlling robots. Gemini Robotics executes smooth movements to tackle a wide range of complex manipulation tasks while also being robust to variations in object types and positions\, handling unseen environments as well as following diverse\, open vocabulary instructions. With additional fine-tuning\, Gemini Robotics can be specialized to new capabilities including solving long-horizon\, highly dexterous tasks\, learning new short-horizon tasks from as few as 100 demonstrations and adapting to completely novel robot embodiments. Furthermore\, I will discuss the challenges\, learnings and future research directions on robot foundation models.

SUMMARY:ESE Guest Seminar - "The Nonlinear Small-Gain Theory for Networks and Control"
DESCRIPTION:The world is nonlinear and linked. In this talk\, I will present the origin of the small-gain theory and show that it serves as an important systematic tool for addressing two fundamental problems for networks: When is a dynamical network robustly stable? When can a dynamical network be made robustly stable by feedback? As an illustration\, we show how the small-gain theory can be applied to unify solutions to event-triggered nonlinear control and provide novel solutions to distributed feedback optimization. Finally\, if time permits\, I will discuss briefly learning-based control\, a new direction in control theory\, that aims to integrate machine learning and nonlinear control techniques to relax the conservativeness of small-gain designs.

SUMMARY:ESE Ph.D. Thesis Defense: "On Riccati Equations in Nonconvex Optimization"
DESCRIPTION:Riccati equations are ubiquitous in systems/control theory and are frequently solved by the methods of continuous optimization. In some cases\, it is known that solutions can be obtained quickly and efficiently by convex-optimization methods\, but small modifications to these settings can easily destroy convexity\, limiting the applicability of convex-optimization methods. This thesis considers manifold and stochastic optimization techniques to address cases where Riccati-Equations/Riccati Constraints cannot be addressed by convex-optimization methods. Specifically\, this thesis studies system-identification\, where Riccati constraints are required to ensure synthesizability\, and in control synthesis\, where Riccati constraints ensure stabilization. The methods developed here yield tractable procedures for identification and synthesis\, extending the reach of Riccati-based design beyond what is accommodated by convex-optimization frameworks.

SUMMARY:PICS Colloquium: Macroscopic stochastic thermodynamics with Massimiliano Esposito [VIRTUAL]
DESCRIPTION:This speaker event is virtual\, but will be screened in PICS 534 with refreshments. \nEquilibrium thermodynamics emerges from equilibrium statistical mechanics as the most likely behavior of a system in the macroscopic limit. Over the last two decades\, significant progress has been made in formulating statistical mechanics for small systems operating far-from-equilibrium. The resulting theory is often called stochastic thermodynamics. I will show that by taking the macroscopic limit of stochastic thermodynamics\, one can formulate a nonequilibrium thermodynamics for large systems\, typically described by nonlinear deterministic dynamics and macroscopic fluctuations around it [1]. This macroscopic stochastic thermodynamics gives rise to novel fundamental results. For instance\, once can bound nonequilibrium steady state fluctuations using the entropy production along deterministic relaxation trajectories [2]. Many classical phenomenological results from macroscopic irreversible thermodynamics are also recovered within well controlled approximations. This theory opens the way to study the energetics of many complex nonlinear phenomena in a broad range of systems\, such as chemical reaction networks (CRNs)\, nonlinear electrical circuits\, and Potts models. \nReferences: \n[1] G.

SUMMARY:ESE Guest Seminar - "Van der Waals Quantum Materials for Magnetism and Clean Energy"
DESCRIPTION:In recent years\, numerous magnetic van der Waals layered quantum materials have been reported\, including transition-metal halides\, transition-metal chalcogenides\, transition-metal phosphorus chalcogenides\, and metal oxy- and chalco-halides. Unlike 3D counterparts\, layered magnets can be easily and rapidly exfoliated to yield ultra-thin magnets\, providing unique opportunities for both fundamental physics and new technologies. Furthermore\, these materials enable unprecedented experimental access to the ground states\, fundamental excitations\, and magnon dynamics\, as they are highly susceptible to external stimuli. In this talk\, I will present and discuss our recent findings in tuning the magnetic properties of quasi-2D layered van der Waals quantum magnets by intercalation\, photoexcitation\, proton irradiation\, and by the application of pressure. If time permits\, I will briefly discuss our recent efforts in solving the problems related to energy materials by employing magnetometry and electron paramagnetic resonance spectroscopy.

SUMMARY:ESE Ph.D. Seminar: "Nonconvex Linear System Identification"
DESCRIPTION:The goal of system identification (SysID) is to learn a mathematical model from a corpus of temporal observations of a system’s inputs and outputs. SysID is a fundamental problem in engineering\, with applications ranging from circuit design to robot control. Classical approaches to linear SysID rely on convex relaxations that offer strong theoretical guarantees. However\, these methods often suffer from scalability issues and are not well-suited for large-scale systems. In this talk\, I will present a nonconvex optimization approach to linear SysID that overcomes these limitations. It is well known that converting convex problems to nonconvex ones can lead to significant computational advantages\, but they typically lack theoretical guarantees. I will show how we managed to achieve the best of both worlds: a faster and theoretically sound algorithm.

SUMMARY:ESE Ph.D. Thesis Defense: "QuINT – Quantum Integrated Network Timing"
DESCRIPTION:This dissertation presents QuINT\, a modular platform for integrating new quantum and optical science into the Internet’s IP-based optical network infrastructure. Building on a recently developed chip-powered quantum-classical hybrid networking framework\, QuINT provides a detailed analysis and design for enhancing the precision of the Network Time Protocol (NTP) beyond that of existing standalone synchronization systems. NTP is the most widely used time synchronization protocol\, coordinating clocks across billions of devices\, including servers\, smartphones\, scientific instruments\, and GPS-enabled systems. The precision of distributed timing and synchronization is often a limiting factor in applications such as financial trading\, position\, navigation and timing (PNT)\, and large-scale scientific experiments. This work includes complete system\, software and hardware specifications\, and contributes to ongoing IETF draft efforts aimed at standardizing quantum-classical network integration\, while demonstrating the real-world impact of silicon photonics as a bridge to a scalable quantum-augmented Internet.

SUMMARY:CBE Doctoral Dissertation Defense: "Colloidal Propulsion by a Topological Flagellum in a Nematic Liquid Crystal" (Jacky Zhang)
DESCRIPTION:Abstract: \nSwimming\, self-organization\, and collective behaviors of active and driven colloids have implications in nature and applications to reconfigurable materials. Here\, we focus on swimming or displacement made possible by the complex topologies of defects within nematic liquid crystals (NLCs). \nIn Newtonian fluids\, colloidal swimming is challenging; broken symmetries or non-reciprocal forcing are needed to achieve a net displacement\, given the reversibility of flows in inertia-free regimes. NLCs\, made of elongated nematogens with highly non-linear elastic free energy\, offer degrees of freedom that change this scenario. NLCs store elastic energy in non-uniform director fields\, spontaneously generate topological defects\, and have complex visco-dynamic responses. Recently\, rotated isotropic spherical colloids have been shown to translate or swim in NLC. This translation under highly symmetric forcing arises through broken symmetries in the viscous stresses which depend on the local director field. Distortions in the director generated by the flow result in net forces on the sphere. \nIn this thesis\, we develop the concept of a topological flagellum\, a defect in the NLC that undergoes non-reciprocal rearrangement near the colloid and aids in its translation. Ferromagnetic disk colloids\, short circular cylinders of finite height\, are rotated in an external magnetic field in an NLC\, which generates translation. For disks with uniform anchoring\, swimming occurs via mechanisms like those for the rotating sphere. For disks with hybrid anchoring\, however\, a companion topological defect near the disk emerges which undergoes a non-reciprocal\, periodic\, elongation\, sweeping and contraction cycle. The disk and defect together periodically store and release elastic energy in a highly directed manner. We identify the defect to be a thick\, non-singular twist wall\, and demonstrate that the sweeping defect occurs via a topological instability in which the sense of twist over the disk changes handedness. We show that defect motion in the super-critical regime aids propulsion by two mechanisms. The sweeping twist wall generates material flows and net viscous shear forces via rotation of nematogens as sweeping occurs. After sweeping\, the defect contracts on the disk’s edge\, driving rotation that aids propulsion. Defect-driven propulsion provides strategies to create soft\, reconfigurable micro-machines powered by the intrinsic physics of structured fluids. \nZoom Information: \nMeeting ID: 988 3278 8468 \nPasscode: 273345

SUMMARY:ESE Ph.D. Thesis Defense: "Design and optimization of laminated metallic cores for high-frequency transformers and inductors"
DESCRIPTION:High-frequency power converters increasingly require magnetic components that are compact\, efficient\, and compatible with advanced integration. Conventional ferrites face limitations in scaling and high-frequency performance. This work introduces laminated NiFe magnetic structures fabricated through CMOS-compatible multilayer electroplating as a promising alternative. The materials and fabrication approach are demonstrated through silicon TSV inductors and transformers\, PCB-integrated inductors\, and discrete coupled inductors and transformers\, with system-level evaluation in corresponding practical converter architectures. The results highlight laminated electroplated NiFe as a promising core material for compact\, high-frequency power converters.

SUMMARY:ESE Ph.D. Dissertation Proposal Defense - "Layering and Task Generalization in Control Architectures"
DESCRIPTION:Learning-based control architectures have unlocked remarkable capabilities in autonomous systems\, from robotic manipulation to autonomous driving and traffic coordination. This progress has motivated the widespread use of layering to manage large-scale systems and multitask control to handle multiple systems and missions. The increasing integration of these architectures into society calls for a rigorous theory that guarantees safety in layered designs and clarifies when multitask controllers can generalize well across tasks. \nIn this talk\, I will present my work on advancing the foundations of layering and task generalization in control architectures. I will first introduce a framework for the co-design of planning and tracking layers in multirate control of constrained linear systems. This framework provides computable tracking error bounds along with safety guarantees for any planner. I will then develop formal measures of task heterogeneity for multitask linear quadratic control and demonstrate how these measures bound the suboptimality of using a shared controller on tasks with distinct objectives\, for both optimal and policy-gradient approaches. These results offer interpretable conditions under which a single controller can perform effectively across many tasks. I conclude with directions for extending these methodologies to nonlinear systems and distributed networks of multiple agents.

SUMMARY:MEAM Seminar: "Modeling and Analysis of Wall-bounded Turbulent Flows"
DESCRIPTION:Most fluid flows at human scales and at moderate speeds (> 1 m/s) reach Reynolds numbers of at least 10⁴ or higher\, causing even tiny disturbances to amplify and drive the flow toward turbulence. Turbulence is a broadband\, continuum phenomenon: turbulent eddies of vastly different time and length scales enhance the mixing and transport of momentum\, heat\, and scalars through chaotic fluctuations. These processes critically affect system performance\, influencing drag/lift/noise/vibration on lifting surfaces\, energy-conversion efficiency (e.g.\, wind turbines and combustion engines)\, and the spread of pollutants or airborne diseases. \nIn this talk\, I will highlight computational research from my group on modeling wall-bounded turbulent flows\, analyzing laminar–turbulent transition through stability theory\, and developing Lagrangian approaches for turbulent momentum transport. I will first summarize my work on wall-modeled large-eddy simulation (WMLES)\, a leading technique for affordable\, scale-resolving simulations of wall turbulence\, applied to both canonical configurations (flat plates\, channels) and complex geometries (aircraft and atmospheric flows over sand dunes). I will then discuss the relevance of boundary layers with intrinsic three-dimensionality in these complex flows and present our recent efforts to understand turbulence transition originating from a three-dimensional base flow. Lastly\, I will showcase our ongoing research on extracting Lagrangian information in a fully Eulerian manner—without particle tracking—which has revealed previously unseen flow phenomena that warrant further investigation.

SUMMARY:Rigorous and Glamorous in 100 Words or Less 2.0 - An Abstract-Writing Workshop
DESCRIPTION:It’s hard to write an abstract. It’s harder to write a glamorous one that tells your story without overselling your results. Last year\, we hosted a virtual abstract-writing workshop where our P.I.\, Konrad Kording\, reviewed and refined students’ abstracts live. Back by popular demand\, the workshop returns — this time with a bonus! Participants can use the scientific project planner app\, PlanYourScience.com\, to kickstart a new study or fine-tune an existing one.\n\n\n\n \n\nRSVP here and submit your abstract for a chance to have it workshopped with Konrad Kording\, live.\nWe will notify you if your abstract was selected for review.\n\n\nYou can also join the workshop without submitting an abstract.\n\n\n\n\n\n*Community for Rigor will not use submitted work for any purposes outside of this event\n*If you have any questions\, email us at carogar@seas.upenn.edu

SUMMARY:Academic Innovation Speaker Series: “A’s for All” (as time and interest allow)
DESCRIPTION:Traditional grading paradigms often fail to cater to diverse learning paces and styles\, potentially sidelining those needing more time to learn the material. “A’s for All” (as time and interest allow) is an innovative pedagogical philosophy that builds on grading for equity\, mastery learning\, growth mindset\, and competency-based approaches. It gives every student the opportunity and time to learn the material\, including working beyond the term. It removes barriers and late penalties\, and sends a strong signal to students that they can achieve any level of mastery they want\, if they are willing to put in the time and effort. We will share the principles of “A’s for All” and actionable insights to refine and enhance teaching methodologies. We hope this talk will sow the seeds for a more inclusive\, flexible\, and student-centric future in STEM education.
