GPS Applied Mathematics Seminar
The GPS (Graduate Participation Seminar) is a weekly seminar by and for graduate students. If you're interested in presenting a topic or your own research, contact the organizers: Sarah Tumasz, Qin Li, Peter Mueller, and Bryan Crompton.
All seminars are on Fridays from 9:55-10:45 am in room 901 VV. Speakers should aim for their talk to last no longer than 45 minutes.

Fluid-body interactions: from fish to flagella
abstract: The length and velocity scales of swimming organisms on this planet vary by many orders of magnitude. Some swimming strategies work for small organisms but not for large ones, and vice versa, due to the scale-dependent nature of the fluid dynamics governing such systems. In this informal conversation, we will discuss some classical and recent efforts to understand fluid-body interactions at scales relevant to fish and birds, and separately to microorganisms. The methodology for their study will range from classical tools of applied mathematics to highly accurate numerical techniques. Questions to be addressed (briefly) include: what is the optimal waveform of an undulating flagellum?; what is the effect of boundaries on swimming microorganisms?; and what is the role of flexibility in flapping fins and wings?
