    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    As the adoption of large-scale learning for control continues to grow, developing sample-efficient algorithms has become critical. Yet, even in simple settings, algorithms achieving optimal sample complexity for specific problem instances often remain unknown. Motivated by this limitation, we discuss recent progress toward understanding sample-efficient methods in learning-enabled control. We first examine the statistical limits […]

    MEAM Ph.D. Thesis Defense: “Elastomeric Strain Limitation for Design of Soft Pneumatic Actuators”

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

    Modern robots embody power and precision control, yet as robots undertake tasks that apply forces on humans this power brings risk of injury. Soft robotic actuators use deformation to produce smooth, continuous motions and conform to delicate objects while imparting forces capable of safely pushing humans. This thesis presents strategies for the design, modeling, and […]

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

    Fibers are among the most versatile material forms in contemporary applications, including textiles, biomedicine, and aerospace. Wet spinning, the process of coagulating a polymer solution into tangible fibers, remains one of the oldest and most reliable methods for continuously fabricating fibers from a wide range of materials. Contemporary research in fiber science has begun to […]

    CBE Doctoral Dissertation Defense: “Reconfigurable Metasurfaces Based on Multistable Elastic Pixels” (Jed-Joan S. Edziah)

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

    Abstract: Metamaterials are engineered materials designed to manipulate and tailor electromagnetic (EM) waves. Metasurfaces are planar metamaterials that rely on inclusions whose optical properties and spatial arrangements are designed to interact with incident EM waves to yield desired reflected or transmitted waveforms. A reconfigurable metasurface in which the relative positions of inclusions can be controlled […]

    /
    Towne 319 220 S. 33rd Street, Philadelphia, United States

    Crosslinked biocompatible polymer networks offer unique potential for biomedical applications that demand high resilience under repetitive load-bearing conditions. However, conventional hydrogels often exhibit poor mechanical strength and irreversible damage under cyclic deformation. To address these challenges, this work presents a class of engineered polymer network designed for enhanced mechanical robustness: cryogel-based double-network (DN) hydrogels. In […]

    CBE Doctoral Dissertation Defense: “Computational Strategies for Efficiently Sampling Conformational Changes in Solvated Macromolecules” (Akash Pallath)

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Abstract: Solvated macromolecules such as proteins and polymers undergo conformational changes in response to stimuli such as pressure, temperature, pH, ligand binding, and post-translational modification. These transitions are fundamental to biological function, from cellular signaling to misfolding and aggregation, and are increasingly harnessed in applications such as drug delivery, biosensing, and biomaterials design. Understanding how […]

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

    Abstract: Micron-scale colloidal particles with short-ranged attractions, e.g., colloids functionalized with single-stranded DNA oligomers, have emerged as a powerful platform for studying colloidal self-assembly phenomena with the long-term goal of identifying routes for metamaterial fabrication. Although these systems have been investigated extensively both experimentally and computationally, the role of ‘real world’ features that may impact […]

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

    Robots are complex, high-dimensional systems, governed by nonlinear, underactuated dynamics and evolving on non-Euclidean manifolds, posing numerous challenges for control synthesis and analysis. While optimization-based methods of control can flexibly accommodate diverse dynamics, costs, and constraints, they often demand coarse approximations or powerful onboard processors (infeasible for many aerial and space systems) due to their […]
