CBE Seminar Series: “Developing Strategies for Polymer Redesign and Recycling Using Reaction Pathway Analysis” (Linda Broadbelt, Northwestern University)

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

Abstract: The current lack of sustainability of and the limited portfolio of recycling processes for synthetic polymers have posed serious threats to the environment. Using reaction pathway analysis, we are pursuing a portfolio of strategies for redesign and recycling of polymers for sustainability. Pyrolysis is a promising method for resource recovery from plastic waste that […]

MEAM Seminar: “Mechanics for Energy Sustainability: From Fatigue of 2D Materials to Dendrites in Solid-state Batteries”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Achieving energy sustainability requires efforts from not only sourcing clean energy, but also storing and dispatching energy whenever and wherever needed, as well as being energy-efficient whenever possible. Two-dimensional (2D) materials hold great promises as mechanical reinforcement in high strength-to-weight ratio structural materials and as next-generation energy-efficient electronic materials, both of which contribute to less […]

MSE Seminar: “Design of Stable Nanocrystalline Alloys: Thermodynamics, Computation, and Data Science” (Massachusetts Institute of Technology)

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

Over the last three decades, nanocrystalline alloys (polycrystals with grain sizes of less than 100 nm) have been shown to exhibit superior material properties, such as enhanced specific strength, hardness, wear resistance, radiation resistance, and magnetic properties. However, such structures are inherently thermodynamically unstable; a nanocrystalline configuration comes with a large volume fraction of high-energy […]

Spring 2023 GRASP on Robotics: Jitendra Malik, University of California at Berkeley, “Robots that Learn and Adapt”

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 via Zoom. This week's presenter will be in-person as well.    ABSTRACT Deep learning has resulted in remarkable breakthroughs in fields such as speech recognition, computer vision, natural language processing, and protein structure prediction. Robotics has proved to be much […]

MEAM Seminar: “Solid Interfaces in Electrochemical Devices”

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

While lithium (Li) ion battery technology has had major successes, at the current rate of progress, it is unlikely to meet the mid-century global demands related to full de-carbonization and interruption of fossil fuel usage for transportation and energy generation. The replacement of currently used anodes by Li metal is one of the most promising […]

MSE Seminar: “Chemical Bonds in Topological Materials” (Princeton University)

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Topological materials are solid-state compounds that have atypical charge carriers, often acting analogously to particles in high-energy physics. They are significant for both fundamental and applied science, with potential uses in spintronics, catalysis, and quantum information science. But despite the great promise of this field, the majority of known topological materials conform to the same […]

ASSET Seminar: Statistical and Machine Learning for Electronic Health Records: Challenges and Opportunities, Qi Long (University of Pennsylvania)

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

ABSTRACT: Electronic health records (EHRs) offer great promises in advancing clinical research and transforming learning health systems. However, complex, temporal EHRs are fraught with biases and present daunting analytical challenges that, if not addressed, can exacerbate health inequities. EHRs data, recorded at irregular time intervals with varying frequencies, are multi-modal and multi-scale including structured data […]

Spring 2023 GRASP SFI: Edward Hu, University of Pennsylvania, “Focusing on Task-Relevant Information in RL for Robots”

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

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. This week's presenter will be in-person as well. ABSTRACT While it is tempting to view robotics as a nail that can be solved with the deep learning hammer, we have seen that deep-learning based perception and action pipelines for […]

CBE Seminar Series: “Decisions through Oscillation: Learning from Endothelial Cells” (Andre Levchenko, Yale University)

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

Abstract: Blood vessels constitute one of the most complex and most essential biological systems, sometimes referred to as a separate organ. Endothelial cells, lining blood vessels are also one of the most 'plastic' cell types, capable of a wide range of responses to external stimuli, conditioned on their internal states and micro-environment. Strikingly, many of […]
