MEAM Seminar: “Stretching the Boundaries of Medical Robotics”

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

Abstract: My lab creates medical robots not only for minimally invasive surgery, but also for targeted drug delivery and for tissue regeneration. This talk will describe three of our technologies. The first consists of tetherless robots that are powered, controlled and imaged using an MRI scanner. These devices vary from patient-mounted needle-driving robots to capsules […]

ESE Seminar: “Towards a Seamless Integration of Drones in Smart Cities: Communications and Security”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

The use of unmanned aerial vehicles (UAVs), popularly known as drones, will be an integral component of emerging smart city applications ranging from delivery of goods to flying taxis. However, a seamless deployment of such drone-based applications requires addressing technical challenges across communications, security, autonomy, and control. In this talk, we focus on the wireless […]

CIS Seminar: “What Should We Do With Persistent Main Memory?”

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

Memory systems are on the verge of a renaissance: Scalable, persistent main memories (e.g., Intel’s 3DXPoint) are the first new technology to enter the upper layers of the memory hierarchy in 50 years. They bring a fundamentally new capability (i.e., persistence), a dramatic increase in capacity, and an array of complications (e.g., asymmetric read and […]

MEAM Seminar: “Viewing Earth’s Surface as a Soft Matter Landscape”

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

The Earth's surface is composed of a staggering diversity of particulate-fluid mixtures: dry to wet, dilute to dense, colloidal to granular, attractive to repulsive particles, laminar to turbulent flows, and steady to highly-unsteady forcing. This material variety is matched by the range of relevant stresses and strain rates, from rapid and catastrophic landslides to the […]

ESE Seminar: “Efficient Mid-Infrared Photodetection Using Graphene Plasmons at Room Temperature”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

In the history of materials development, many classic materials (Si, III-Vs, organics, etc.) which can be produced reliably at large scale eventually have found critical applications after decades of intensive research, leveraging their distinctive properties. For example, silicon dominates the field-effect-transistor technology because perfect dielectric-silicon interface can be readily realized. Organic materials are currently widely […]
