ESE Ph.D. Thesis Defense: “Machine Learning for Large-Scale Cyber-Physical Systems”
Directly training deep learning models for applications in large-scale cyber-physical systems can be intractable due to the large number of components and decision variables. Instead, we focus on exploiting spatial symmetries in systems by designing size-generalizable architectures. Once trained on small-scale examples, such architectures exhibit equivalent or comparable performance on large-scale systems. The first example […]

ESE Ph.D. Thesis Defense: “Inverse design for engineering complex light-matter interaction”
The inverse design paradigm has emerged as a transformative approach for the synthesis of nanophotonic structures, offering a powerful alternative to conventional intuition-driven design. By approaching photonic device design as a computational optimization problem, inverse design enables the systematic exploration of high-dimensional parameter spaces to uncover non- intuitive structures that meet complex performance targets. This […]

NOAS facilitates the visualization of quantum biological electron transfer processes occurring in mitochondria within living cells, supports the precise […]
CBE Doctoral Dissertation Defense: “Designing Solvent-Based Order Parameters for Characterizing Binding of Surfaces with Different Hydrophobicity Using Molecular Dynamics Simulations” (Jun Lu)
Abstract: Life is dependent on water: most self-assembly and binding processes of biomolecules take place in water. Water-mediated interactions are an essential driving force behind these processes, which is largely affected by the hydrophobicity of the binding surfaces. As many biomolecular binding interfaces are amphiphilic, the hydrophobic interactions are largely affected by polar and charged […]
ESE Ph.D. Thesis Defense: “Graph Neural Networks for Communication in Multi-Agent Systems”
Communication networks support a wide range of applications in multi-agent systems by solving core problems such as routing, scheduling, and resource allocation. In this thesis, we focus on data-driven routing and scheduling strategies using local information subject to constraints using Graph Neural Networks (GNNs). First, we study information routing in communication networks with constant channel […]

ASSET Seminar: “Fake News, Echo Chambers, and Algorithms: A Data Science Perspective”
Abstract: American democracy has been undermined by an “infodemic” of fake news, coupled with the widespread segregation of consumers into ideologically homogenous echo chambers by inscrutable algorithms deployed by rapacious social media platforms—or so we are told. In this talk, I will critically examine claims of this sort—made frequently by politicians, journalists, and public intellectuals—summarizing […]

IDEAS/STAT Optimization Seminar: “Negative Stepsizes Make Gradient-Descent-Ascent Converge”
Zoom link: https://upenn.zoom.us/j/98220304722 Abstract: Solving min-max problems is a central question in optimization, games, learning, and controls. Arguably the most natural algorithm is Gradient-Descent-Ascent (GDA), however since the 1970s, conventional wisdom has argued that it fails to converge even on simple problems. This failure spurred the extensive literature on modifying GDA with extragradients, optimism, momentum, anchoring, […]
MEAM Master’s Thesis Defense: “Learning a Vision-Based Footstep Planner for Hierarchical Walking Control on Unstructured Terrain”
Bipedal robots demonstrate high potential in navigating challenging terrains through dynamic ground contact. However, current frameworks often depend solely on proprioception or use manually designed visual processing pipelines, which are fragile in real-world settings and complicate real-time footstep planning in unstructured environments. To overcome this problem, this work proposes a vision-based hierarchical control framework that […]
BE-Grace Hopper Distinguished Lecture: Melody Swartz, PhD “Immunoregulatory roles of lymphatic vessels in cancer and opportunities for immunoengineering”
Tumor lymphangiogenesis, which involves both the activation and growth induction of surrounding lymphatic vessels, is well-known to correlate with tumor progression and metastasis in many solid tumors. While it is typically assumed that lymphangiogenesis supports an ‘escape route’ for cells to leave the primary tumor, the tumor-draining lymph node serves as the key site of […]
