Title: Hydrodynamics of microorganisms - from individual to collective swimming
Abstract:
Hydrodynamics is essential for the self-propulsion of microorganisms, their mutual interactions and nutrient mixing in the surrounding fluid. Many structural properties of flagella or cilia (the microscopic appendages that propel bacteria and algae through their fluid environment) remain conserved in higher organisms, where they are known to play important roles in the reproductive system, during embryonal development and in the respiratory tract. Thus, studying the hydrodynamics of microorganisms not only helps to reveal the physical properties of the simplest life forms, but also promises general insights that could be of medical importance in the future. In this talk, I will discuss recent experimental and theoretical progress in our understanding of the fluid flows generated by individual algae and bacteria. Specifically, I will present results from the first direct measurements of the E.coli flow field and discuss their implications for biofilm formation and collective swimming in bacterial suspensions.
Lunch: Group 1
