DESCRIPTION:Speaker: David Nelson\nAbstract: It is widely appreciated that 
 population waves have played a crucial role in the evolutionary history of
  many species. Neutral mutations optimally positioned at the front of a gr
 owing population wave can increase their abundance via a "surfing" phenome
 non. Similar issues arise in growing spherical cell clusters\, where cell 
 division is confined to the cluster surface\, and genetic drift -- the dis
 crete nature of cells -- can be very important. This kind of growth occurs
  in cells proliferating in soft agar\, and can also serve as a simple mode
 l of avascular tumors. We discuss the survival probability for both circul
 ar and spherical range expansions\, and find that it is strongly influence
 d by inflation at the frontier. Experimental and theoretical studies of th
 ese effects will be presented\, as well as recent attempts to extend stati
 stical dynamics ideas to microorganisms cooperating and competing in the t
 urbulent environment of the ocean.
