CBE Seminar: “Probing Protein Interactions from Molecular to Cellular Scales with Microscale Technologies”

Zoom - Email CBE for link

Abstract Biological molecules rarely act alone. For example, in many pediatric cancers, a chromosomal rearrangement results in a fusion protein with altered DNA and protein interactions that yield proliferative and aggressively metastatic cell subpopulations. In this talk, I will describe quantification of molecular interaction properties relevant to fusion oncoprotein biology using microscale tools with distinct […]

Spring 2021 GRASP SFI: “Hunting for Unknown Unknowns: AI and Ethics in Society”

Zoom

Abstract: Homo Sapiens is considered a “hyper-cooperative species,” and this aptitude for cooperation may be responsible for our dominance over the Earth. Cooperation promises great benefits, but each participant is vulnerable to exploitation by their partners. Successful cooperation requires trust: acceptance of vulnerability, with confidence that it will not be exploited. The culture of any society […]

ESE Seminar: “Sensing the Physical World using Pervasive Wireless Infrastructure”

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

Emerging applications such as smart cities, autonomous vehicles, and mixed reality rely on embedded systems that are engaging with the physical environment through sensors. Building upon this connection, my vision is to advance Omnipresent Sensing by harnessing the wireless infrastructure in and around buildings and cities to act as a non-intrusive sensing platform. This is possible by […]

BE Seminar: “Dissecting Multicellular Therapeutic Responses Using a Large-scale Single-cell Profiling Platform” (Siyu Chen)

This event will be held virtually via Zoom (check email or contact ksas@seas.upenn.edu). Human diseases are fundamentally multicellular in nature with many different cell types contributing to disease progression and treatment response. However, how therapeutics impact each cell type in a heterogeneous population remains poorly understood because most studies are focused on isolated cell types […]

GRASP On Robotics: “Photoacoustic Vision for Surgical Robots”

Zoom

Abstract: The concept of “x-ray vision” is widely understood to be the ability to see through structures that are not transparent to the human eye. This concept would be a useful feature for surgeons and surgical robots, particularly when navigating complex anatomy. The Photoacoustic & Ultrasonic Systems Engineering (PULSE) Lab is developing imaging systems to […]

MEAM Seminar: “Fusion for Robot Perception and Controls”

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

Machine learning has led to powerful advances in robotics: deep learning for visual perception from raw images and deep reinforcement learning (RL) for learning controls from trial and error. Yet, these black-box techniques can often require large amounts of data, have results difficult to interpret, and fail catastrophically when dealing with out-of-distribution data. In this […]

MEAM Ph.D. Thesis Defense: “Reactive Planning with Legged Robots in Unknown Environments”

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

Unlike the problem of safe task and motion planning in a completely known environment, the setting where the obstacles in a robot's workspace are not initially known and are incrementally revealed online has so far received little theoretical interest, with existing algorithms usually demanding constant deliberative replanning in the presence of unanticipated conditions. Moreover, even […]

Spring 2021 GRASP SFI: “Safe and Data-efficient Learning for Robotics”

Zoom

Abstract: For successful integration of autonomous systems such as drones and self-driving cars in our day-to-day life, they must be able to quickly adapt to ever-changing environments, and actively reason about their safety and that of other users and autonomous systems around them. Even though control-theoretic approaches have been used for decades now for the […]

CBE Seminar: “Metal-Organic Frameworks as Tunable Platforms for Gas Storage, Chemical Separations and Catalysis”

Zoom - Email CBE for link

Abstract Metal-organic frameworks (MOFs) are a versatile class of nanoporous materials synthesized in a “building-block” approach from inorganic nodes and organic linkers.  By selecting appropriate building blocks, the structural and chemical properties of the resulting materials can be finely tuned, and this makes MOFs promising materials for applications such as gas storage, chemical separations, sensing, […]
