MEAM Seminar: “Force, Shape, and Motion in Collective Cell Migration”

Cells migrate collectively to form tissues, to heal wounds, and, in cancer, to metastasize. During these biological processes, the collective migration exhibits a transition from a solid-like state, wherein cell positions remain fixed, to a fluid-like state, wherein cells flow freely and rearrange their positions with their neighbors. Recent mechanics-based models and experiments have demonstrated […]

MEAM Seminar: “Nanoparticle Heating for Therapeutics, Regenerative Medicine and Diagnostics”

Gold and iron oxide nanoparticles have unique and tunable properties that allow transduction of optical (light), or radiofrequency (RF) electromagnetic fields to affect heating of biomaterials at multiple scales. This talk will explore the underlying physics and relative advantages of each form of nanoparticle heating for therapeutic treatment of cancer or other disease by heating […]

PICS Seminar: “Coupled Multiphysics Models of Cardiac Hemodynamics: From Fundamental Insights to Clinical Translation”

  Abstract: The mammalian heart has been sculpted by millions of years of evolution into a flow pump par excellence. During the typical lifetime of a human, the heart will beat over three billion times and pump enough blood to fill over 60 Olympic-sized swimming pools. Each of these billions of cardiac cycles is itself a […]

MEAM Seminar: “Interfacial Soft Matter”

Surface tension plays a critical role in a wide range of biological, environmental, technological and geophysical settings. In this talk, I will present three different problems dealing with interfacial soft matter that find motivation in markedly diverse areas. First, I will discuss the evaporation kinetics and flow dynamics of non-spherical sessile drops undergoing phase change. […]

MEAM Seminar: “Fluid Mechanics and Turbulence in Extended Wind Farms”

In this presentation we discuss several properties of the flow structure and turbulence in the wind turbine array boundary layer (WTABL). This particular type of shear flow develops when the atmospheric boundary layer interacts with an array of large wind turbines. Based on such understanding, we aim to develop reduced order, analytically tractable models. These […]

MEAM Seminar: “Hairy Hydrodynamics”

Flexible slender structures in flow are everywhere. While a great deal is known about individual flexible fibers interacting with fluids, considerably less work has been done on fiber ensembles — such as fur or hair — in flow. These hairy surfaces are abundant in nature and perform multiple functions from thermal regulation to water harvesting […]

MEAM Seminar: “Elastomeric Materials for Autonomic Force Transmission, Optoelectric Sensing, and 3D Printing Soft Robots”

This talk will present multidisciplinary work from material composites and robotics. We have created new types of actuators, sensors, displays, and additive manufacturing techniques for soft robots and haptic interfaces. For example, we now use stretchable optical waveguides as sensors for high accuracy, repeatability, and material compatibility with soft actuators. For displaying information, we have […]

MEAM/GRASP Seminar: “Geometric Biologically Inspired Robots that Span Industries from Medical to Manufacturing”

The animal kingdom is full of both human and non-human animals worthy of investigation, emulation and re-creation. As such, my research group has created a comprehensive research program focusing on biologically-inspired robots, and has applied them to search and rescue, minimally invasive surgery, and manufacturing. These robots inspire great scientific challenges in mechanism design, control, […]

MEAM Seminar: “Viewing Earth’s Surface as a Soft Matter Landscape”

The Earth’s surface is composed of a staggering diversity of particulate-fluid mixtures: dry to wet, dilute to dense, colloidal to granular, attractive to repulsive particles, laminar to turbulent flows, and steady to highly-unsteady forcing. This material variety is matched by the range of relevant stresses and strain rates, from rapid and catastrophic landslides to the […]

MEAM Seminar: “Stretching the Boundaries of Medical Robotics”

Abstract: My lab creates medical robots not only for minimally invasive surgery, but also for targeted drug delivery and for tissue regeneration. This talk will describe three of our technologies. The first consists of tetherless robots that are powered, controlled and imaged using an MRI scanner. These devices vary from patient-mounted needle-driving robots to capsules […]
