CIS Seminar:”Probabilistic proofs: theory, hardware, and everything in between”

Zoom - Email CIS for link cherylh@cis.upenn.edu

In the past decade, systems that use probabilistic proofs in real-world applications have seen explosive growth. These systems build upon some of the crown jewels of theoretical computer science---interactive proofs, probabilistically checkable proofs, and zero-knowledge proofs---to solve problems of trust and privacy in a wide range of settings. This talk describes my work building systems […]

ODEI Event: Do You Have a Crew? The Importance of Friendship in Creating a Fulfilling Life

Don’t isolate. Congregate! Join Penn Engineering’s Office of Diversity, Equity, and Inclusion to meet six dynamic men and learn about how their bonds of friendship and NSBE affiliation benefited them personally and professionally. Hear their story and engage in Q&A for the first hour (7PM-8PM). Then, meet someone new in breakout groups (8PM-8:30PM). An additional […]

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 […]

PICS Colloquium: “Learning about learning by many-body systems”

Abstract: Many-body systems from soap bubbles to suspensions to polymers learn the drives that push them far from equilibrium. This learning has been detected with thermodynamic properties, such as work absorption and strain. We progress beyond these macroscopic properties that were first defined for equilibrium contexts: We quantify statistical mechanical learning with representation learning, a […]

ODEI Spotlight: USABE Fireside Chat with Dr. CJ Taylor

Fireside Chat with Dr. CJ Taylor Date: Friday, February 26th Time: 4:00 - 5:00 PM EST Join USABE on Friday, February 26th at 4 PM for a conversation with Dr. CJ Taylor, Associate Dean for Diversity, Equity, and Inclusion at Penn Engineering, to discuss his experiences in STEM and engineering and his role as a […]

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 […]

MSE Seminar: “Engineering topological phases in graphene moiré heterostructures”

Taming topological electronic phases is a fundamental challenge and an important milestone on the way towards novel electronic devices and topological quantum computation. Recent advances in fabrication techniques have made van der Waals (vdW) heterostructures one of the most active platforms for the experimental investigation of topological electronic phases in 2D. Moiré superlattices, which arise […]

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 […]

CIS Seminar: ” Exterminating bugs in real systems”

Zoom - Email CIS for link cherylh@cis.upenn.edu

Software is everywhere, and almost everywhere, software is broken. Some bugs just crash your printer; others hand an identity thief your bank account number; still others let nation-states spy on dissidents and persecute minorities. This talk outlines my work preventing bugs using a blend of programming languages techniques and systems design. First, I'll talk about […]
