MSE Seminar: “Managing Intercultural Interactions in a Challenging Global Higher Education Landscape”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

The rapidly diversifying face of colleges and universities in the United States including the University of Pennsylvania require that we are able to manage intercultural relationships from different backgrounds. We are all working in a multicultural institution, with students, faculty and staff from all over the world. This makes for a very diverse, vibrant community […]

MEAM Special Seminar: “Smartphone-based Mobile Detection Platform for Molecular Diagnostics: from Infectious Diseases to Cancer”

Towne 227 (MEAM Conference Room) 220 S. 33rd Street, Philadelphia, PA, United States

Rapid, quantitative molecular diagnostics in the field, at home, and in resource poor settings is needed for evidence-based disease management, control, and prevention. Conventional molecular diagnostics requires extensive sample preparation, sophisticated instruments, and trained personnel, restricting their use to centralized laboratories. To overcome the limitations of laboratory-based procedures, we designed a simple, inexpensive, hand-held, smartphone-based […]

PICS Seminar: “High-order Spectral Difference Method for Studying Marine Hydrodynamics and Thermal Convection and Magneto-hydrodynamics for the Sun”

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

Abstract Two recent advancements of high-order spectral difference (SD) method for computational fluid dynamics on unstructured meshes will be presented. The first progress is our contribution to a new curved sliding-mesh approach to the SD method for simulating flapping and rotary wing aerodynamics.  The second elevation of the SD method is our recent successful design […]

MEAM Seminar: “Multi-Stable Morphing Structures”

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

Variable geometry “morphing” structures can achieve different geometric configurations through overall deformation, but usually many actuators are required for shape control. In this talk we consider a particular type of morphing structure that is able to switch configuration with only a few actuators. It is based on the concept of embedding by design local energy […]

ESE Seminar: “Metasurface Computational Imaging”

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

Modern image sensors consist of systems of cascaded and bulky spherical optics for imaging with minimal aberrations. While these systems provide high-quality images, the improved functionality comes at the cost of increased size and weight. One route to reduce a system’s complexity is via computational imaging, in which much of the aberration correction and functionality […]

CIS Seminar: “Contesting Secure Development to Understand Security Mistakes”

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

Abstract:  With the ongoing, frequent disclosure of the existence and exploitation of security vulnerabilities, one might wonder: How can we can build software that is more secure? In an attempt to focus educational attention on this question, and gather empirical evidence at the same time, we developed the Build it, Break it, Fix it (BIBIFI) […]

CBE Seminar: “Tailoring Processes and Assembly of Nanomaterials for Electrochemical Energy Storage”

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

Abstract: Despite their promise to mitigate many problems and offer new opportunities in energy storage systems, nanomaterials have proven to be difficult to tailor and preserve their assembly throughout manufacturing processes when a scale-up is considered. My group has been working on understanding and modification of instability-driven processes to devise scalable manufacturing processes such as […]

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 […]

PICS Seminar: “Mathematical Modeling of Thrombin-Fibrin Binding Dynamics”

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

Abstract: Blood clot formation involves the coupled processes of platelet aggregation and coagulation, which are triggered when there is break in a blood vessel. Platelet aggregation is largely a physical process while coagulation is biochemical, consisting of a large network of reactions that culminate in the generation of the enzyme thrombin. Thrombin cleaves fibrinogen into […]
