MSE Lab Safety Seminar
MSE Thesis Defense: “High Loading Oxide Anodes for Lithium Ion Batteries via a Superelastic Graphene Composite Approach”
/
LRSM 325
3231 Walnut St., Philadelphia, PA
MEAM Seminar: “Dynamical Systems Approach to Geophysical and Aerospace Flows”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
A dynamical systems approach is taken to explain the dynamics of two classes of ‘gap-leaping’ geophysical flow as well as the hypersonic second-mode instability. First, in the context of a loop current system, it is shown that multiple steady flow patterns with hysteresis exist and appear to satisfy a cusp catastrophe geometry of solutions. Which […]
CBE Seminar: “Complexity in the Chemistry and Physics of Lipid Membranes as a Handle to Activate the Delivery of Cargo to Cells”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
Abstract: Lipid materials having nanostructures that deviate from the conventional flat bilayer arrangement such as hexagonally packed lipid tubes and bi-continuous cubic phases are ubiquitous in nature. Their role remains elusive but over the years several pathologies and organelle functions have been coupled to lipid membrane structural complexity. In this talk, we will discuss lipid membrane polymorphism and […]
PRiML Seminar: “Building Algorithms by Playing Games”
/
Room 401B, 3401 Walnut
3401 Walnut Street, Philadelphia, PA, United States
A very popular trick for solving certain types of optimization problems is this: write your objective as the solution of a two-player zero-sum game, endow both players with an appropriate learning algorithm, watch how the opponents compete, and extract an (approximate) solution from the actions/decisions taken by the players throughout the process. This approach is very […]
MEAM Seminar: “Engineering Microdevices Using Atomic Layer Deposition and Electrowetting”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
This talk will cover 1) devices created one atomic layer at a time and 2) electrowetting optical elements. Atomic layer deposition (ALD) and Atomic Layer Etching (ALE) are self-limiting processes that enable accurate atomic-scale thickness control either through deposition or etching of various materials. We are developing novel manufacturing processes that study how ALD materials […]
ESE & Statistics Seminar: “Large Neural Networks: Insights from Linearized Models”
/
PICS Conference Room 534 - A Wing , 5th Floor
3401 Walnut Street, Philadelphia, PA, United States
Abstract: Modern machine learning models, and in particular multilayer neural networks, exhibit a broad range of puzzling phenomena. Their training requires to minimize a highly non-convex high-dimensional cost function, and yet it is efficiently addressed using simple gradient descent (GD) or stochastic gradient descent (SGD) algorithms. This model contains more parameters than the number of […]
CBE Seminar: “Evolution of the Conformational-free Energy Landscapes of Proteins”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
Abstract: One of the holy grails of drug-design is to obtain high-selectivity binding of a drug to the target protein, an extremely challenging endeavor for proteins that share high sequence and structural similarity. We investigate several systems of high biological importance to elucidate how selectivity emerged during evolution and how it can inform the design […]
MSE Professional Development Seminar: “Interviewing with Confidence”
/
Auditorium, LRSM Building
3231 Walnut Street, Philadelphia, PA, United States
CIS Seminar: “What Society Must Require from AI”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
Abstract: Artificial intelligence (AI) algorithms, especially machine learning (ML) programs, are now being employed or proposed for use in: a) scanning résumés to weed out job applicants; b) evaluating risks children face in their families; c) informing judicial decisions about bail, sentencing, and parole; d) diagnosing medical conditions, and not just classifying medical images; e) […]
PSOC Seminar : Collagen architecture regulates metabolic stress and collective invasion

MEAM Seminar: “Robot Design Concepts for Intuitive Physical Human-robot Interaction”
/
Wu and Chen Auditorium (Room 101), Levine Hall
3330 Walnut Street, Philadelphia, PA, United States
Physical human-robot interaction (pHRI) aims at taking advantage of the complementary capabilities of robots and humans. One of the key challenges in pHRI is to provide a high-bandwidth human-robot interaction that is safe and intuitive for the human user. To this end, it is proposed in this work to revisit the design of robots in […]
