Control Theory and Cellular Motility in Stokes Flow
Swimming, i.e., being able to advance in the absence of external forces by performing cyclic shape changes, is particularly demanding at low Reynolds numbers which is the regime of interest for micro-organisms and micro-robots.
First, we will explain the mechanical bases of cellular motility. Starting from observations of biological self-propulsion, we will analyze the geometric structure underlying motility at small scales. Then, by using control theory, we will examine to what extent the presence of a plane wall affects the motility of micro-swimmers.
