BE Grace Hopper Lecture: Powering tumor cell migration through heterogeneous microenvironments

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

To move through tissues, cancer cells must navigate a complex, heterogeneous network of fibers in the extracellular matrix.  This network of fibers also provides chemical, structural and mechanical cues to the resident cells.  In this talk, I will describe my lab’s efforts to understand the forces driving cell movements in the tumor microenvironment.  Combining tissue […]

Sigma Aldrich Lecture: “Epitaxy by Design: Epitaxial Growth of Dissimilar Materials”

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

Abstract:   The ability to integrate dissimilar materials with different crystal structures and properties enables heterostructures to be developed with new functionality well beyond the normal band gap engineering offered by semiconductor heterostructures. The combination of metals, semiconductors, insulators, magnetic, piezoelectric, structural and phase change materials offers the potential for nearly limitless control of device properties. […]

Herman P. Schwan Distinguished Lecture: “Engineering human tissues for medical impact”

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

The classical paradigm of tissue engineering involves the integrated use of human stem cells, biomaterial scaffolds (providing a structural and logistic template for tissue formation) and bioreactors (providing environmental control, dynamic sequences of molecular and physical signaling, and insights into the structure and function of the forming tissues). This “biomimetic” approach results in an increasingly […]

Britton Chance Distinguished Lecture: “Regenerative Immunology: The Role of Technology Translation in Guiding Discovery”

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

Abstract: Biomaterial implants have a long history in the clinic, but regenerative biomaterials and regenerative medicine therapies, in general, have been slow to reach patients. Clinical translation provides a unique and critical opportunity to investigate the key therapeutic drivers of technology efficacy in people. Careful evaluation of clinical outcomes and reevaluation of design parameters is […]

POSTPONED: John A. Quinn Distinguished Lecture: “Molecular and Colloidal Interactions in Water”

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

Abstract: Life occurs in water, and water-mediated interactions between molecules and interfaces are central to biological assembly processes.  Synthetic materials as common as shampoo rely on water-mediated interactions.  This presentation will describe experiments that highlight our lack of understanding of interactions in water. This lack of understanding presents the opportunity to formulate a refined set […]

CIS Seminar: “Recovering, manipulating and enhancing recorded speech (1905-2020)”

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

This talk will survey several recent projects dealing with recorded speech. The first explores an optical process for recovering sound recorded onto postcards using a forgotten technology from more than a century ago. This involves scanning the postcard at multiple orientations using a flatbed scanner, and then reconstructing the fine scale surface texture of the […]

ESE Grace Hopper Lecture: “Emerging Non-Volatile Ferroelectric Memory”

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

Abstract The last decade has seen a remarkable shift in usage and value of semiconductor memory technologies. These changes are driven by the elevation of four particular target applications –(1) mobile multi-media applications, (2) explosive growth in the sheer volume of data that is being created and stored, (3) emphasis from the individual components to […]

ESE Seminar: “Data-driven Decision Making and Estimation in CPS/IoT Networks”

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

The modern instantiation of a sensor network is a cyberphysical (CPS) system where CPS subsystems can be interconnected by a shared communication network of limited bandwidth. A common problem in CPS networks is the sensing and communication of spatio-temporal signals. However, there are fundamental differences between estimation (sensing) and communication. For example, the type of […]

ESE Grace Hopper Lecture: “Scalable Photonics: An Optimized Approach”

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

Classical and quantum photonics with superior properties can be implemented in a variety of old (silicon, silicon nitride) and new (silicon carbide, diamond) photonic materials by combining state of the art optimization and machine learning techniques (photonics inverse design) with new fabrication approaches. In addition to making photonics more robust to errors in fabrication and […]

Inaugural Joseph Bordogna Forum: “A Call to Action for Racial Justice and Equity in Engineering”

https://upenn.zoom.us/j/96715197752

Racism and anti-Blackness are crises that jeopardize our democracy, productivity and well-being and call into question whether we can all live together peaceably and harmoniously in a just and equitable American society. At this critical moment in our nation’s history we need more than words that renounce racism and anti-Blackness, we need actions to abolish […]
