PRECISE Seminar: “Communication and Sensing with Laser Light”

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

Abstract The physical properties of laser light make it a perfect medium for a plethora of applications. Examples include high-bandwidth data communication thanks to its fast modulation speed, efficient power delivery given its high energy density, and fine-grained human sensing and object tracking because of its nanometer-level wavelength. Despite its potential, laser light still faces […]

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 […]

ESE Fall Seminar – “Quantum sensing and imaging with diamond spins”

Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single nuclear spins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene […]

PICS Colloquium: “Modeling Assembly of Colloids with Charges and with Mobile Binders”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

In this talk, I will present our recent efforts in probing the physical processes underlying self-assembly of colloidal gels and crystals. Nano-meter to micron sized particles in suspension can be a powerful platform for assembly novel functional materials, but the challenge is to design interactions such that desired functionality is achieved. Moreover, for practical purposes […]

MEAM Seminar: “Hardware / Controls Co-design to Overcome Challenges for Aerial Robots”

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

Aerial robotics have become ubiquitous, but (like most robots) they still struggle to operate at high speed in unstructured, cramped environments. By considering a vehicle's mechanical design simultaneously with the design of controls and automation algorithms, we have more degrees of freedoms to find creative solutions to problems. In this talk I will present some […]

CIS Seminar: “Modeling Atoms to Address Our Climate Crisis”

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

Climate change is a societal and political problem whose impact could be mitigated by technology. Underlying many of its technical challenges is a surprisingly simple yet challenging problem; modeling the interaction of atoms. In this talk, we motivate the problem and provide insights into how this opens up new intriguing directions for machine learning and […]

ASSET Seminar: “Copyright, Machine Learning Research, and the Generative-AI Supply Chain” (A. Feder Cooper, Cornell University)

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

ABSTRACT: “Does generative AI infringe copyright?” is an urgent question. It is also a difficult question, for two reasons. First, “generative AI” is not just one product from one company. It is a catch-all name for a massive ecosystem of loosely related technologies. These systems behave differently and raise different legal issues. Second, copyright law […]

Fall 2023 GRASP SFI: E. Farrell Helbling, Cornell University, “Autonomy for insect-scale 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 on Zoom. ABSTRACT Countless science fiction works have set our expectations for small, mobile, autonomous robots for use in a broad range of applications. The ability to move through highly dynamic and complex environments can expand capabilities in search and rescue […]

CBE Seminar: “Structure-Independent Peptide Binder Design via Generative Language Models” (Chatterjee, Duke University)

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

The ability to modulate pathogenic proteins represents a powerful treatment strategy for diseases. Unfortunately, many proteins are considered "undruggable" by small molecules, and are often intrinsically disordered, precluding the usage of structure-based tools for binder design. To address these challenges, we have developed a suite of algorithms that enable the design of target-specific peptides via […]

MSE Seminar: “Nonlinear and Topological Quantum Photonics” University of Central Florida

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

In this talk we will discuss how to engineer the dispersion relation of photonic platforms to provide robust propagation of classical and quantum states of light. In the first part of this talk, we will unveil how to leverage the interaction of nonlinearity with higher orders of dispersion to create novel types of solitons, wave […]
