Mathematical modeling reveals mysteries of bacterial swimming
Swimming bacteria with helical flagella are self-propelled micro-swimmers in nature, and the swimming strategies of such bacteria vary depending on the number and the arrangement of flagella on the cell body. In this talk, I will introduce a few different species of microorganisms that belong to either monotrichous, lophotrichous, or peritrichous bacteria. To simulate swimming bacteria in viscous fluid, we have developed the neutrally buoyant rigid body dynamics theory to describe the motion of the cell body that can translate and rotate, and the unconstrained Kirchhoff rod theory to describe the motion of long but thin helical flagella. The hydrodynamic interaction between the fluid and the bacteria is described by the regularized version of Stokes flow. I will focus on how bacteria can swim and reorient swimming course for survival and show how Mathematics can help to understand the swimming mechanism of such bacteria.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
