ESE Seminar: “Beyond Supervised Learning for Biomedical Imaging”

Smilow Center Auditorium 3400 Civic Center Blvd, Philadelphia, PA, United States

Abstract: Today, many biomedical imaging tasks, such as 3D reconstruction, denoising, detection, registration, and segmentation, are solved with machine learning techniques. In this talk, I will present a flexible learning-based framework that has allowed us to derive efficient solutions for a variety of such problems, without relying on heavy supervision. I will primarily employ image […]

MEAM Special Seminar: “Differences in Material Properties of Trabecular Bone Tissue from Modeling- and Remodeling-Based Bone Formation in Rats”

CRB Auditorium 415 Curie Boulevard, Philadelphia, PA, United States

Bone undergoes continuous changes during life through processes of bone modeling and remodeling. Modeling-based bone formation (MBF) i.e. bone formation without prior activation of osteoclastic resorption, only occurs during growth, healing, and in response to external mechanical loading. Remodeling-based bone formation (RBF), which is tightly coupled with bone resorption by osteoclasts, plays a predominant role […]

MSE Seminar: “In-Situ Resistance Degradation & Switching of Bulk Fe-doped SrTiO3 and Yttria-Stabilized Zirconia”

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

Perovskite-type titanates are the standard dielectric used in multilayer ceramic capacitors (MLCCs), and yttria-stabilized (YSZ) is the prototypical fast oxygen conductor used in solid oxide fuel cells (SOFCs) and oxygen sensors. Under a DC electric field, the resistance of YSZ and Fe-doped strontium titanate (Fe-STO) degrades in an indistinguishable way. This is surprising because, unlike […]

ESE PhD Thesis Defense: “Affordances and Control of a Spine Morphology for Robotic Quadrupedal Locomotion”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Abstract: How does a robot’s body affect what it can do? This talk explores this question with respect to a morphology common to biology but rare in robotics: the presence of a bendable back. Using the Canid and Inu quadrupedal robots, I describe and quantify several advantages afforded by this morphological design choice for legged […]

MEAM Doctoral Dissertation Defense: “Estimation, Mapping and Navigation with Micro Aerial Vehicles for Infrastructure Inspection”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Multi-rotor Micro Aerial Vehicles (MAV) have become popular robotic platforms in the last decade due to their manufacturability, agility and diverse payload options. Amongst the most promising applications areas of MAVs are inspection, air delivery, surveillance, search and rescue, real estate, entertainment and photography to name a few. While GPS offers an easy solution for […]

BE Seminar: “High-throughput T cell repertoire profiling enabled systems immunology and immune engineering”

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

T cells are important to the initiation, prevention, and cure of many diseases. For example, various T cells based cancer immunotherapies have been quite effective in treating several types of cancers. However, a significant fraction of patients do not respond. A comprehensive understanding of the complexity of the T cells repertoire in health and diseases […]

MEAM Seminar: “Confined Curved Shells and their Elaborate Conformations”

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

Curved shells, when confined, can deform to a broad assortment of large scale shapes and smaller scale wrinkling and folding patterns quite unlike what produced by their flat counterparts. The intrinsic, natural curvature of shells is the central element that allows for this rich and very interesting morphological landscape, but it is also the source […]
