Reception immediately following the lecture.
Abstract: The motion of waving or rotating filaments in a fluid environment is a common element in many biological and engineered systems. Examples at the microscale include bacterial flagella propelling a cell body and engineered helical nanorobots designed to deliver drugs to tumors. Complex fluid environments, such as networks of polymers, can have dramatic effects upon the dynamics of microorganisms as they move through mucus or tissues. In this talk we will present a mathematical and computational framework used to model these viscosity-dominated flows. We will investigate a few intriguing systems: actin-like fibers in straining flows that spontaneously buckle into helices, helical filaments that penetrate and break a polymeric network, and the journey of extremely long insect sperm flagella through narrow and tortuous female reproductive tracts.
