April 11, 2022 -CBE PhD Dissertation Defense | “Understanding the relationship between clot contraction and platelet biology under hemodynamic conditions”
MEAM Ph.D. Thesis Defense: “Relationships Between Structure, Dynamics, and Flow in Sheared Amorphous Materials”
Amorphous solids, those composed of haphazardly arranged constituents, are found everywhere from our windows as silicate glass, in the ground and foundations as mud and concrete, and our grocery stores as granular piles of oranges. Even though they can be found over a huge range of length scales, it remains a challenge to systematically design […]

CBE PhD Dissertation Defense | “Understanding the relationship between clot contraction and platelet biology under hemodynamic conditions”
Abstract: "As thrombosis proceeds, platelets in a clot can expose phosphatidylserine (PS), providing a negatively charged surface for thrombin generation. These PS+ platelets have been shown to sort to the perimeter of platelet masses via platelet contraction. However, it remains unclear how thrombin and fibrin affect PS+ platelet sorting within a clot. We used an […]

April 12, 2022 -MEAM Ph.D. Thesis Defense: “Mechanical Properties of Fibrous Network Materials”
MEAM Seminar: “The Statistical Mechanics of Granular Clogging”
The gravity-driven flow of grains from a hole in a hopper is an iconic granular phenomenon. It’s different from a fluid in that the rate is independent of fill height, and more spectacularly so in that it can suddenly and unexpectedly clog. How does the susceptibility to clogging decrease with increasing hole size, and is […]
CBE PhD Dissertation Defense | “The role of clot structure and mechanics on hemodynamics and pharmacology”
Abstract: "Hemostatic clots have a core/shell hierarchy comprised of a P-selectin positive core surrounded by a P-selectin negative shell. A new human blood microfluidic assay utilizing a 2-stage assay was developed to interrogate core/shell mechanics. By first perfusing whole blood over a collagen/TF surface and then swapping out the blood for buffer, we were able […]
MEAM Ph.D. Thesis Defense: “Metal and Air Generate Power for Robots”
In many cases, the size and weight of energy storage technologies required to power robotic systems are too large or massive for a robot to carry, leading to limited operational times and long recharging times over which the robot remains unused. Computer-free autonomous decision making based on environmental cues provides exciting alternatives to classic control […]
MEAM Ph.D. Thesis Defense: “Mechanical Properties of Fibrous Network Materials”
We discuss mechanical behavior of specific fibrous network materials, including the evolution of tension in fibrin clots, compression of pulmonary emboli, and fracture of Whatman filter paper. The first material, fibrin clots, consist of random networks of fibrin fibers. When clots form by polymerization they develop tensile pre-stresses. We construct a mathematical model for the […]

Spring 2022 GRASP SFI: Georgios Georgakis, University of Pennsylvania, “Cross-modal Map Learning for Vision and Language Navigation”
*This will be a HYBRID Event with in-person attendance in Levine 512 and Virtual attendance via Zoom We consider the problem of Vision-and-Language Navigation (VLN) in previously unseen realistic indoor environments. Arguably, the biggest challenge in VLN is grounding the natural language to the visual input. The majority of current methods for VLN are trained end-to-end […]
CBE Seminar: John A. Quinn Distinguished Lecture – “Molecular and Colloidal Interactions in Water”
Abstract Life occurs in water, and water-mediated interactions are central to biomolecular assembly processes. Synthetic materials as common as soap and shampoo also rely on water-mediated interactions. This presentation will describe experiments that highlight our lack of understanding of interactions in water. The opportunity to formulate a refined set of design rules for self-assembly of […]

April 14, 2022 -MEAM Seminar: “Exploiting Environmental Fields for Orienteering and Planning Problems”
MSE Seminar: “Role of Solvation and Dynamics on Ion Transport in Polymer Electrolytes”
Polymer electrolytes are an important class of ion conducting materials critical to enabling various electrochemical systems. Fundamentally, ion-polymer coordination, inter-connectivity of solvation sites, and corresponding ion-solvating polymer dynamics are critical in understanding the limits of ionic conductivity. Here, the importance of these effects is highlighted in a series of combined experimental and computational studies on […]
GRASP Special Seminar: Steven Ceron, Cornell University, “Swarms Across Length Scales with Local-to-Global Behaviors”
*This will be a HYBRID Event with in-person attendance in Towne 337 and Virtual attendance via Zoom Collectives in nature demonstrate behaviors that extend far beyond the capabilities of any single agent. Social slime mold, for example, has thousands of cells that aggregate and form mobile and immobile nutrient-searching structures as a function of chemical signals. […]
MEAM Seminar: “Exploiting Environmental Fields for Orienteering and Planning Problems”
Robots are increasingly being used to complete tasks in complex environments. To complete these tasks, two of the most fundamental choices that the robot must make are (1) task planning: which tasks to complete and in what order, and (2) path planning: what path to take when navigating between those tasks. In this seminar, I […]

GRASP on Robotics: Vincent Sitzmann, Massachusetts Institute of Technology, “Self-supervised Scene Representation Learning for Robotics”
Given only a single picture, people are capable of inferring a mental representation that encodes rich information about the underlying 3D scene. We acquire this skill not through massive labeled datasets of 3D scenes, but through self-supervised observation and interaction. Building machines that can infer similarly rich neural scene representations is critical if they are […]

PICS Colloquium: “Transforming Healthcare from the Outside: the OBSERVER project”
We live with a health care system that has evolved into an increasingly fragmented, primarily treatment-oriented, and now heavily burdened environment. More importantly, issues related to privacy, space, and disease transmissibility have limited access to non-medical personnel who might offer creative, evidence-based, radical change to the health care system, as proposed years ago by the […]
