Explorations in Biofluids: a Tale of Two Tails
CAMS Colloquium Joint with Aerospace and Mechanical Engineering
In the past decade, the study of the fluid dynamics of swimming organisms has flourished. With the possibility of using fabricated robotic micro swimmers for drug delivery, or harnessing the power of natural microorganisms to transport loads, the need for a full description of flow properties is evident. At a larger scale, the swimming of a simple vertebrate, the lamprey, can shed light on the coupling of neural signals to muscle mechanics and passive body dynamics in animal locomotion.
We will present recent progress in the development of a multiscale computational model of the lamprey that examines the emergent swimming behavior of the coupled fluid-muscle-body system. At the micro scale, we will examine the function of a flagellum of a dinoflagellate, a type of phytoplankton. We hope to demonstrate that, even when the body kinematics at zero Reynolds number are specified, there are still interesting fluid dynamic questions that have yet to be answered.
Dr. Lisa Fauci was educated in the New York City public school system, received her B.S. at Pace University, and later her Ph.D. in Mathematics at the Courant Institute of Mathematical Sciences, NYU in 1986. She joined the faculty of Tulane University in New Orleans the same year. She was the founding Director of the Center for Computational Science at Tulane in 2001, currently serves as an Associate Director, and is the Nola Lee Haynes Pendergraft Professor of Mathematics. She has held visiting positions at New York University and the University of Utah, and has lectured throughout the world. Her research lies at the interface of mathematics, scientific computing and biology.
