    • ESE Ph.D. Thesis Defense: “Machine Learning on Large-Scale Graphs”

    /
    Room 452 C, 3401 Walnut 3401 Walnut Street, Philadelphia, PA, United States

    Graph neural networks (GNNs) are successful at learning representations from most types of network data but suffer from limitations in large graphs, which do not have the Euclidean structure that time and image signals have in the limit. Yet, large graphs can often be identified as being similar to each other in the sense that […]

    MEAM Ph.D. Thesis Defense: “Enhancing Strength and Toughness Via Reinforcement with Nanocellulose Fibers”

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

    Cellulose nanofibrils (CNFs) are a nanomaterial obtained from plant sources and have excellent mechanical properties, high aspect ratios, and are biodegradable. As a reinforcing phase, CNFs have the potential to improve the mechanical properties of polymer materials. The overarching objective of this thesis is to investigate the use of CNFs to enhance the strength and […]

    • MEAM Seminar: “Mixing with Activity: Transport of Swimming Microorganisms in Complex Flows”

    /
    Towne 313 220 S. 33rd Street, Philadelphia, PA, United States

    How will swimming microorganisms affect the mixing of a diffusive contaminant in chaotic flows? Answers to this question can lead to improved understanding of the spread of pollutants (e.g. algal blooms) in oceans and lakes, as well as potentially useful applications in biofuel and vaccine productions. In this talk, I present recent experiments on the […]

    MEAM Seminar: “Sedimentation of Active Suspensions: Hindrance and Phase-separation”

    /
    Towne 313 220 S. 33rd Street, Philadelphia, PA, United States

    Sedimentation of active matter is found in many natural and industrial processes. It plays an important role on the distribution of plankton in oceans, which is key part of the carbon cycle (i.e. ocean's biological pump) that transports carbon from the ocean's surface to depth. In this seminar, I will present an investigation on the […]

    ESE Ph.D. Thesis Defense: “Optical and Spin Dynamics of Quantum Emitters in Hexagonal Boron Nitride at Room Temperature”

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

    Hexagonal boron nitride (h-BN) is a van der Waals material that hosts defect-based quantum emitters (QEs) at room temperature, providing an unparalleled platform for realizing devices for quantum technologies and studying light-matter interactions. Recent observations suggest the existence of multiple distinct defect structures responsible for QEs. Theoretical proposals suggest vacancies, substitutional atoms, and their complexes as likely […]

    ESE Ph.D. Thesis Defense: “Learning Environmental Models with Multi-Robot Teams Using a Dynamical Systems Approach”

    /
    PERCH 303, Pennovation 3rd Floor 3401 Grays Ferry Avenue, Bldg 6176, Philadelphia, PA, United States

    Robots have the capability to sense and track natural phenomena for environmental monitoring, deepening our understanding of the world. Robotic modeling of such phenomena is essential to operating in complex environments, allowing robots to perform in more realistic scenarios. Thus, representing complex environments is paramount to the success of multi-robot teams. While considerable efforts have […]

    ESE Ph.D. Thesis Defense: “Creating dynamical robots of different morphologies and sizes through automatic origami design”

    /
    Levine 307 3330 Walnut Street, Philadelphia, PA, United States

    Origami robots are machines whose morphologies and functions are created by folding locally flat sheets. This thesis makes three contributions to the design and fabrication of origami robots aimed at the development of an automated computational pipeline for the specification and construction of widely different morphologies and body sizes capable of highly dynamic operation. The […]
