Existing devices—such as cell phones, computers, and robots – are made from rigid materials, which is in direct contrast to the soft materials that compose the human body. In this talk, I will discuss several topics related to studying and harnessing soft materials within the context of creating devices with tissue like properties. Liquid metal: Gallium-based […]
Abstract: In this talk, we introduce a new class of problems related to integrating inertial measurements obtained from an IMU that play a significant role in navigation combined with visual data. While there have been tremendous technological advances in the precision of instrumentation, integrating acceleration and angular velocity still suffers from drift in the displacement […]
*This seminar will be held in-person in Levine 307 as well as virtually via Zoom. ABSTRACT In the realms of health and sports, quantitative analysis of human movement provides guidance for individualized performance characterization, training, and health assessment. Data collection for biomechanical analysis of human motion is typically performed using expensive, specialized hardware that requires experiments […]
Rapid advancements in healthcare, technology, finance and beyond present significant opportunities and challenges. As we look to develop leading-edge solutions to provide a better future for all, Penn Engineering and Perry World House are committed to promoting responsible innovation practices. Join us for an inspiring afternoon as we launch the Responsible Innovation initiative at the […]
Lymphatic, nervous, and tumoral tissues, among others, exhibit physiology that emerges from three-dimensional interactions between genetically unique cells. Technologies capable of volumetrically imaging transcriptomes, genotypes, and morphologies in a single de novo measurement can provide a critical lens into the biological complexity of living systems. We present experimental and computational work to develop DNA microscopy: […]
This will be a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT We are witnessing a space renaissance. Tens of thousands of broadband low Earth orbit (LEO) satellites are expected to be launched by the end of this decade. These planned megaconstellations of LEO satellites along with existing […]
Enhancing the resistance of human-made brittle materials to fracture is challenging due to the limited microstructural toughening mechanisms. This seminar makes a case for engineering toughening mechanisms in brittle materials by developing purposeful architected arrangements of material inspired by natural systems. Experimental fracture mechanics in hard-soft (cementitious-elastomeric) ‘Nacre-like’ composites based on the tabulated brick-and-mortar arrangement […]
Update 10/14/24: Please note the new time and location for Nina Ghosn's Doctoral Dissertation Defense below. The Department of Bioengineering at the University of Pennsylvania and Dr. Brian Litt are pleased to announce the Doctoral Dissertation Defense of Nina Ghosn. Title: DATA DRIVEN APPROACHES FOR OPTIMIZING ANTISEIZURE MEDICATION MANAGEMENT IN EPILEPSY Advisor: Brian Litt Date: October […]
AI-powered applications are exciting because of their potential to support people in unprecedented ways but they are also particularly challenging to design right: How does one design a useful AI-enabled product if the underlying AI is occasionally wrong? How can we make these applications feel predictable even though the AI technology is complex and can […]
Abstract: As the impact of artificial intelligence (AI) continues to proliferate, computer architects must assess and mitigate its environmental impact. This talk will survey strategies for reducing the carbon footprint of AI computation and datacenter infrastructure, drawing on data and experiences from industrial, hyperscale systems. First, we analyze the embodied and operational carbon implications of […]
This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT People experience the world through modalities of sight, sound, words, touch, and more. By leveraging their natural relationships and developing multimodal learning methods, my research creates artificial perception systems with diverse skills, including spatial, physical, logical, and […]
Abstract: The posttranslational modifications (PTMs) in RiPPs (ribosomally synthesized and post-translationally modified peptides) dictate their 3D structure and their bioactivity. An underlying structural feature of many RiPPs is macrocyclization, installed by a growing number of different enzymatic strategies. Another common class of PTM in RiPPs is backbone modification, such as the formation of thiazol(in)es and […]
