In the first half of my talk, I will focus on computing the bacteria motor torque value, an elastohydrodynamic instability that enables swimming of peritrichous bacteria, and lastly, a fluid-structure interaction instability that causes bacterial cells swimming near surfaces to become surface-bound rather than swim in circular trajectories. In the second half, I will focus on an electrohydrodynamic instability called Quincke rotation and is usefulness in making self-propelled particles, collectively forming active matter. The dynamics of such electrically-driven particles are governed by well-understood Laplace and Stokes equation, making them an ideal system for studying active matter.
