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: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.

SUMMARY:Fall 2025 GRASP SFI: Minghan Zhu\, University of Pennsylvania\, "3D Robot Vision for Structured World Understanding"
DESCRIPTION:This presenter is one of the winners of the 2025 GRASP vote for internal PhD or postdoc SFI Speakers! \nThis is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom.  \nABSTRACT\nDeploying robots in diverse real-world environments is a fundamental challenge. While recent AI advances are impressive\, robots still struggle to generalize. I argue that a key missing piece in embodied intelligence is the structured understanding of the world: how geometries compose\, how physics governs interactions\, and how dynamics unfold. My research in 3D vision develops this understanding with two complementary principles: physics-based reasoning and symmetry-aware learning. First\, I present Vysics\, fusing vision and contact-rich physics to overcome heavy occlusions in object reconstruction\, and my recent follow-up work that further incorporates 3D generative priors for reconstructions with both high visual fidelity and physical compliance. Then\, I demonstrate my work on leveraging symmetry for efficient modeling of 3D geometry and dynamics. I introduce my algorithmic contributions in equivariant learning\, including E2PN\, which improves the efficiency of point cloud learning by 7x compared with prior work\, and Lie Neurons and Reductive Lie Neurons\, which expand the scope of symmetry preserved by equivariant networks from rotations to general linear transformations. These advances enable significant progress in various robotic tasks by incorporating symmetry\, from segmentation and place recognition to odometry and dynamics learning. I will close with my vision of building structured world representations that are simultaneously grounded in physics\, informed by data\, and structured by symmetry\, toward robots that truly understand their physical world.

SUMMARY:CBE Seminar: "New Technologies for Delivery of Nucleic Acids and Proteins to Plants” (Markita Landry\, UC Berkeley)
DESCRIPTION:Abstract:  \nGenetic engineering of plants is at the core of sustainability efforts\, natural product synthesis\, and agricultural crop engineering. Plant bioengineering requires delivery of biomolecules for genetic or post-transcriptional manipulation of plants\, however\, current delivery methods either suffer from host range limitations\, low transformation efficiencies\, tissue regenerability issues\, tissue damage\, or unavoidable DNA integration into the host genome. We briefly discuss prior efforts in delivering DNA plasmids and small interfering RNAs to mature plant cells [1-7]\, and challenges in implementing these approaches for the delivery of proteins. While there exist numerous methods for nucleic acid delivery in plants\, few options exist for protein delivery: biolistics and proptoplast-based PEG transformation\, each with considerable drawbacks. Here\, we report the discovery that plant homeoproteins [8]\, specifically the 3rd alpha helix of the homeodomain\, are generally cell penetrating to walled plant cells with implications for both plant biotechnology and fundamental plant biology. We catalog plant homeoproteins and explore natural variation in the 3rd alpha helix of homeodomains derived from plant homeoproteins. We select a subset of identified 3rd alpha helix peptides for their ability to penetrate mature plant cells and demonstrate these plant derived peptides internalize to plant cells in an amino acid sequence and concentration dependent manner. Finally\, we demonstrate delivery of recombinant protein cargo Cre recombinase and transcription factors utilizing these plant-derived peptides\, into a broad range of plant tissues ranging from single-cell zygotes through mature plant tissues. Our work provides the foundation for tagging proteins with CPPs for their seamless and biolistic-independent delivery to walled plant cells\, enabling a broad range of transgene-free plant biotechnology applications. \n1.

SUMMARY:MSE Seminar:  "Ion Transport in Hydrated Anion Conducting Polyelectrolytes" - Paul F. Nealey - Pritzker School of Molecular Engineering of the University of Chicago\, Senior Scientist at Argonne National laboratory
DESCRIPTION:The realization of next-generation electrochemical technologies demands anion-conducting polymers that break the fundamental trade-offs between conductivity\, stability\, and swelling. Ion transport in these materials is a complex\, emergent property that arises from the coupling of water dynamics\, nanoscale morphology\, and polymer chemistry across multiple length and time scales. \nIn this talk\, I will present a unified mechanistic picture of ion motion in a versatile family of polynorbornene-based polyelectrolytes. We have developed a multiscale framework that integrates simultaneous measurements of ion transport and water uptake in thin films with advanced spectroscopy\, scattering\, and molecular dynamics simulations. This approach enables us to directly connect local solvation dynamics on sub-picosecond time scales to the formation of a percolated\, water-mediated network that governs macroscopic conductivity. \nThe first part of the talk I focus on how water facilitates ion transport across different conductivity regimes\, revisiting long-standing concepts such as vehicular diffusion. I then show how the interplay between water-enabled transport and the thermodynamics of water uptake produces an unexpected convergence in conductivity across polymers with different ion-exchange capacities. Building on this insight\, in the second part I demonstrate a strategy to overcome the usual relationship between transport and swelling. By engineering polymers with spatial charge density fluctuations\, it is possible to decuple percolation from bulk water content and achieve high conductivity even at substantially reduced water and charge concentrations. These findings establish a mechanistically grounded design principle for anion-conducting polymers that achieve high performance while maintaining mechanical and chemical resistance.

SUMMARY:LAMP Seminar: "Mechanics of Contact\, Friction\, and Fracture (by design) - Towards the Interaction between the Natural and Built Environment"
DESCRIPTION:Contact\, friction\, and fracture are fundamental processes governing the emergent (mechanical) behaviors of various complex (material) systems\, from as large as tectonic slip to as small as third-body wear. In this talk\, we briefly discuss (1) challenges in understanding the (nonlinear) mechanics of these processes\, specifically focusing on those designed into metamaterials\, and (2) novel engineering applications they may lead to\, specifically in the context of enabling sustainable interaction between the natural and built environment.

SUMMARY:MEAM Ph.D. Thesis Defense: "Real Time Local Wind Inference for Robust Autonomous Navigation"
DESCRIPTION:Urban air mobility and autonomous package delivery represent promising avenues for integrating aerial robots into everyday life. However\, operating these systems safely and efficiently in windy urban environments remains a major challenge due to the complexity of urban wind flow fields. Existing methods for predicting and navigating wind fields rely on precise environmental knowledge\, distributed sensor networks\, or extensive exploration. On the contrary\, this thesis presents a solution that enables aerial robots to reason about surrounding wind flow fields in real time using on board sensors and embedded flight hardware. \nThe core novelty of this research is the fusion of range measurements with sparse in situ wind measurements to predict surrounding flow fields. We aim to address two fundamental questions: first\, the sufficiency of topographical data for accurate wind prediction in dense urban environments; and second\, the utility of learned wind models for motion planning with an emphasis on energy efficiency and obstacle avoidance. Drawing on tools from deep learning\, fluid mechanics\, and optimal control\, we establish a framework for local wind prediction using navigational LiDAR\, and then incorporate local wind model priors into a receding-horizon optimal controller to study how local wind knowledge affects energy use and safety during autonomous navigation. \nThrough simulated demonstrations in diverse urban wind scenarios we evaluate the predictive capabilities of the wind predictor\, and quantify improvements to autonomous urban navigation in terms of crash rates and energy consumption when local wind information is integrated into the motion planning. Sub-scale free flight experiments in an open-air wind tunnel demonstrate that these algorithms can run in real time on an embedded flight computer with sufficient bandwidth for stable control of a small aerial robot.\nPhilosophically\, this thesis contributes a new paradigm for localized wind inference and motion planning in unknown windy environments.\nBy enabling robots to rapidly assess local wind conditions without prior environmental knowledge\, this research furthers the safe introduction of aerial robots into increasingly challenging environments.

SUMMARY:ASSET Seminar: "Reality Checks"
DESCRIPTION:Despite its success\, leaderboard chasing has become something researchers dread and mock. When implemented properly and executed faithfully\, leaderboard chasing can lead to both faster and easily reproducible progress in science\, as evident from the amazing progress we have seen with machine learning\, or more broadly artificial intelligence\, in recent decades. It does not however mean that it is easy to implement and execute leaderboard chasing properly. In this talk\, I will go over four case studies demonstrating the issues that ultimately prevent leaderboard chasing from a valid scientific approach. The first case study is on the lack of proper hyperparameter tuning in continual learning\, the second on the lack of consensus on evaluation metrics in machine unlearning\, the third on the challenges of properly evaluating the evaluation metrics in free-form text generation\, and the final one on wishful thinking. By going over these cases\, I hope we can collectively acknowledge some of our own fallacies\, think of underlying causes behind these fallacies and come up with better ways to approach artificial intelligence research. \n  \nZoom: https://upenn.zoom.us/j/96405514259

SUMMARY:ASSET Seminar: "Formal Methods for Language Model Systems"
DESCRIPTION:Formal methods are often dismissed as too rigid\, complex\, or unscalable for frontier language model systems (e.g.\, LLMs\, VLMs\, agentic systems). In this talk\, I will challenge this assumption with both theoretical insights and empirical evidence across various domains\, including chatbots\, autonomous driving\, mathematical reasoning\, code generation\, and agentic AI.\n\nI will present a new set of efficient formal frameworks for LLMs that:\n\nSpecify and verify safety properties (e.g.\, secure code generation\, catastrophic risk)\, yielding stronger guarantees than standard evaluation methods such as benchmarks or red teaming.\nGuide generation with semantic guardrails\, ensuring outputs respect formal constraints\, substantially improving both reasoning performance and safety.\nTrain models that are more performant and safer\, and synthesize agents that provably adhere to formally specified constraints (e.g.\, privacy\, resource consumption).\n\nTogether\, these advances demonstrate that formal methods provide a principled foundation for improving the utility\, safety\, and efficiency of frontier language model systems. \n  \n  \nZoom: https://upenn.zoom.us/j/98203000874

SUMMARY:MSE Seminar: "Polymer Chain-End Chemistry: Unlocking Next-Generation Functional Materials"
DESCRIPTION:End-group functionalization has become a powerful and versatile strategy in polymer science\, enabling precise control over physical properties\, nanoscale self-assembly\, and interfacial functionality without modifying the polymer backbone. In our group’s research\, we have investigated (1) how tailored end groups affect intrinsic polymer characteristics such as thermal transitions\, solubility\, and crystallization behavior\, and (2) how end-group interactions direct polymer self-assembly\, particularly by modulating chain packing\,interfacial curvature\, and phase behavior in block copolymer systems\, including the formation of complex network morphologies. Our goal is to develop synthetic methodologies for polymers with rationally designed end-functional groups\, allowing systematic study of their thermodynamic phase-transition behavior through precise control of molecular interactions. By identifying and tuning key variables\, our work aims to deepen fundamental understanding of polymer science. These insights highlight the transformative potential of end-group chemistry for next-generation polymer materials and provide a foundation for designing functional nanomaterials for emerging applications\, including solid-state battery electrolytes\, mechanical metamaterials\, and optical metamaterials. \nReferences\n1) Hojun Lee\, Sangwoo Kwon\, Jaemin Min\, Seon-Mi Jin\, Jun Ho Hwang\, Eunji Lee\, Won Bo Lee\, and Moon Jeong Park*\, “Thermodynamically Stable Plumber’s Nightmare Structures in Block Copolymers”\, Science 2024\, 383\, 70.\n2) Hojun Lee\, Jihoon Kim\, and Moon Jeong Park*\, “Block Copolymer Electrolytes with Double Primitive Cubic Structures: Enhancing Solid-State Lithium Conduction via Lithium Salt Localization”\, ACS Nano 2025\, 19\, 1251.\n3) Gyuha Jo\, Hyungmin Ahn\, Moon Jeong Park “Simple Route for Tuning the Morphology and Conductivity of Polymer Electrolytes: One End Functional Group is Enough”\, ACS Macro Lett. 2013\, 2(11)\, 990-995.

SUMMARY:MEAM Seminar: "Nonlinear Modeling\, Synthesis\, and Design-for-Additive Manufacturing of Smart Compliant Mechanisms"
DESCRIPTION:Compliant mechanisms have been the subject of intense research in recent decades. Making compliant mechanisms “smart” to form flexible\, adaptive structures is the focus of my research group\, with applications ranging from medical devices to aerospace structures. This seminar will describe recent work on modeling and synthesis approaches for compliant mechanisms with both superelastic material behavior and large deformations\, which have not been considered previously in the literature. This approach allows for design of compliant mechanism-based metamaterials with highly nonlinear tailorable stiffness and enhanced energy absorption. Additionally\, the presentation will cover our method for systematic design of active compliant mechanisms that change shape on demand due to application of external stimulus such as magnetic field. Methods to model and design soft magneto active elastomer devices produced via additive manufacturing will be described. These devices are designed to be robust to geometry variation inherent in additively manufacturing processes.

Their macroscopic mechanical properties\, such as stiffness\, strength\, and stretchability\, are largely governed by network-level features\, including polymer chain length distribution\, crosslink density\, and network heterogeneities and topological defects. Consequently\, recent material design strategies have focused on tailoring network architecture to achieve enhanced mechanical performance. Despite these efforts\, predictive tools that directly connect molecular- and network-scale parameters to macroscopic mechanical response remain scarce. Atomistic simulations are computationally prohibitive at relevant length and time scales\, while continuum models often rely on phenomenological fitting parameters. In this talk\, I will present our recent progress toward a predictive multiscale modeling framework for soft rubbery networks that incorporates microscale physics at the single-chain and network levels.

SUMMARY:Spring 2026 GRASP on Robotics: Ming C. Lin\, University of Maryland\, College Park\, "Learning the Dynamic World "
DESCRIPTION:This event will be in-person ONLY in Wu and Chen Auditorium. \nABSTRACT\nWith increasing availability of data in various forms from images\, audio\, video\, 3D models\, motion capture\, simulation results\, to satellite imagery\, representative samples of the various phenomena constituting the world around us bring new opportunities and research challenges. Such availability of data has led to recent advances in data-driven modeling. However\, most of the existing example-based synthesis methods offer empirical models and data reconstruction that may not provide an insightful understanding of the underlying process in a dynamic world or may be limited to a subset of observations. \nIn this talk\, I present recent advances that integrate classical model-based methods and statistical learning techniques to tackle challenging problems that have not been previously addressed. These include flow reconstruction for urban traffic\, learning heterogeneous crowd behaviors from video\, simultaneous estimation of deformation and elasticity parameters from images and video\, and example-based multimodal display for VR systems. These approaches offer new insights for learning and understanding complex collective behaviors\, developing better models for complex dynamical systems from captured data\, delivering more effective medical diagnosis and treatment\, as well as design and prototyping of personalized apparel. I conclude by discussing some possible future directions and challenges.
