MEAM/GRASP Seminar: “Saltatorial Locomotion on Terrain Obstacles”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Robots often struggle to move through complicated environments from cluttered living spaces to treetop canopies where humans and animals flit with ease. Jumping is an exciting locomotion mode that can enable small ground-based robots to maneuver around large obstacles and gaps in complicated environments. A high-power jumping robot can rapidly traverse obstacles, but the resulting […]

CBE Seminar: “Delineating Mechanisms of BMP-mediated Patterning and Organization During Development Through Integrative Experiment and Simulation”

Zoom - Email CBE for link

Abstract The emergence of coordinated cellular, tissue, and organismal responses rely on complex biological networks. While the connectivity of the networks is increasingly defined, understanding the dynamics of the system and the emergence of coordinated responses at multiple spatial and temporal scales is an unsolved problem in many systems. This is a challenge addressed by […]

ESE Seminar: “Accelerating MRI with Deep Learning”

Zoom - Email ESE for Link jbatter@seas.upenn.edu

Magnetic Resonance Imaging (MRI) can be accelerated by sampling below the Shannon-Nyquist rate via compressed sensing techniques. In this talk, I will consider the problem of optimizing the under-sampling pattern in a data-driven fashion, which has been an open problem for over a decade. For a given sparsity constraint, our method optimizes the under-sampling pattern […]

CBE PhD Dissertation Defense | Polymer Mechanics and Dynamics in Polymer Nanoparticle Composites

Zoom - Email CBE for link

Abstract:  "Polymer nanoparticle composites (PNCs) have become an important topic of research due to their highly tunable macroscopic properties. Compared to the pure polymers, PNCs exhibit increase in mechanical strength, altered thermodynamic properties, and simultaneous improvement in permeability and selectivity in small molecule transport. Understanding the fundamental physics that control the behavior of both components […]

MEAM Seminar: “Merging Human-Machine Intelligence with Soft Materials Technology”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Whereas human tissues and organs are mostly soft, wet and bioactive; machines are commonly hard, dry and biologically inert. Merging humans, machines and their intelligence is of imminent importance in addressing grand societal challenges in health, sustainability, security, education and joy of living. However, interfacing humans and machines is extremely challenging due to their fundamentally […]

ESE Grace Hopper Lecture: “Scalable Photonics: An Optimized Approach”

Zoom - Email ESE for Link jbatter@seas.upenn.edu

Classical and quantum photonics with superior properties can be implemented in a variety of old (silicon, silicon nitride) and new (silicon carbide, diamond) photonic materials by combining state of the art optimization and machine learning techniques (photonics inverse design) with new fabrication approaches. In addition to making photonics more robust to errors in fabrication and […]

CBE Seminar: “The Role of Utilization in Meeting Mid-Century Carbon Removal Targets”

Zoom - Email CBE for link

Abstract The utilization of CO2 broadly applies to any process that transforms captured CO2 into valuable products. These processes strive to achieve any of the following objectives: (1) permanent storage (2) revenue generation and/or (3) avoiding emissions of conventional products with high amounts of embodied carbon. This talk will explore how carbon utilization can be […]

MEAM Seminar: “How to Make Your Ocean Smarter”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Our oceans drive worldwide weather-climate systems; our rivers serve as nutrient conduits; and our marine ecosystems house the largest repository of biodiversity and mineral resources on the planet. Humans have relied on rivers, lakes, and oceans for transportation, energy generation, farming, and recreation throughout our history. And today, robots are critical tools in our stewardship […]

MEAM Ph.D. Thesis Defense: “All-Passive Hardware Architectures for Neuromorphic Computation”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Human brains demonstrate how simple computational primitives can be combined in massively parallel ways to produce networks capable of identifying complicated patterns in sensory data. In contrast, electronic computers adopt hardware architectures that process information serially, leading to higher latency and power consumption when implementing intrinsically parallel algorithms, such as neural networks. This software-hardware architectural […]
