Fall 2023 GRASP Seminar: Donglai Xiang, Carnegie Mellon University, “Modeling Dynamic Clothing for Data-Driven Photorealistic Avatars”

Levine 512

This is a hybrid event with in-person attendance in Levine 512 and virtual attendance on Zoom. ABSTRACT In this talk, I will present research on building photorealistic avatars of humans wearing complex clothing in a data-driven manner. Such avatars will be a critical technology to enable future applications such as VR/AR and virtual content creation. […]

CBE Seminar: “Energetic Constraints on Biological Assembly and Motion” (Murrell, Yale)

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

On small length-scales, the mechanics of soft materials may be dominated by their interfacial properties as opposed to their bulk properties. These effects are described by equilibrium models of elasto-capillarity and wetting. In these models, interfacial energies and bulk material properties are held constant. However, in biological materials, including living cells and tissues, these properties […]

MSE Seminar: “Bioinspired Polymers for Tissue Repair and Regeneration” (Phillip B. Messersmith University of California – Berkeley)

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

It is of great interest for materials scientists to study wet biological adhesives as inspiration for synthetic adhesives that can perform well in wet conditions. A compelling example is given by the adhesive proteins secreted by marine mussels, which have inspired the development of synthetic polymer adhesives and coatings for adhesion to wet surfaces. Mussel […]

BE Seminar: “Robust CRISPR/Cas-based epigenome editing technologies for precision human cell engineering and mechanistic dissection of pathological gene expression” (Isaac Hilton, Rice University)

216 Moore Building

Recent advances in CRISPR/Cas-based epigenome editing technologies have enabled programmable control over human gene expression, chromatin states, and genomic organization. Consequently, these emerging technologies have created new opportunities to engineer human cells for therapeutic benefit and catalyzed innovative ways to functionally interrogate gene regulatory mechanisms in situ. Toward these ends, we have recently developed new […]

Fall 2023 GRASP on Robotics: Leslie Kaelbling, Massachusetts Institute of Technology, “Doing for our robots what nature did for us”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT We, as robot engineers, have to think hard about our role in the design of robots and how it interacts with learning, both in "the factory" (that is, at engineering time) and in "the wild" (that is, […]

MEAM Seminar: “Granular and Photoelastic Avalanches”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Flowing granular materials arise everywhere around us, in industry from pharmaceutical processes to bulk good transport lines, and in nature from snow avalanches to captivating dune fields. In landslides, we have an interesting interplay between microscale (grain-grain contacts) and macroscale processes (continuum behavior). In order to understand critical macroscale processes such as stability of a […]

Fall 2023 GRASP SFI: Matthew D. Kvalheim, University of Maryland, Baltimore County, “Discovering engineering (im)possibilities with geometry and topology”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT I will describe engineering (im)possibilities discovered with geometry or topology. These provide or revoke “hunting licenses” for the search of quantities of interest in three contexts: feedback control, applied Koopmanism, and deep neural network autoencoders. Control-Lyapunov or barrier […]

CBE Seminar: “Transformer-based Hybrid Modeling and Control of Evolving, Nonlinear Processes” (Kwon, Texas A&M University)

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Traditionally, the dynamic modeling of chemical processes has relied on first-principles models grounded in fundamental physics and chemistry laws. These models, primarily formulated through differential equations with constant parameters, enable the calculation of control actions optimizing process operations, taking both process and actuator limitations into account. However, the ever-evolving and nonlinear nature of chemical processes […]

MSE Seminar: “Advanced Analytical Characterization of Next Generation Energy Storage Systems” – Nik Singh – Toyota Research Institute of North America

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Advances in hybrid and electric vehicle technologies combined with a demand for green initiatives have recently motivated necessary diversification in energy storage research. To achieve customer expectations for hybrid and electric vehicles, new battery systems with higher energy densities, power densities and cycle life than the current state-of-art Lithium (Li)-ion battery are needed. Further, to […]

Fall 2023 GRASP on Robotics: Nick Gravish, University of California, San Diego, “Adaptive robots through reconfiguration, compliance, and contact”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT Recent advances in robot materials and algorithms have enabled new levels of adaptive and versatile behavior. In this talk I will describe my lab’s efforts to create robots, mechanisms, and control algorithms capable of adaptive behaviors in […]
