SUMMARY:Modeling and topological data analysis of pattern

DESCRIPTION:Pattern formation is present at many scales in bio
 logy\, and here I will focus specifically on eluci
 dating how brightly colored cells interact to form
  skin patterns in zebrafish. Wild-type zebrafish a
 re named for their dark and light stripes\, but mu
 tant zebrafish feature variable skin patterns\, in
 cluding spots and labyrinth curves. All of these p
 atterns form as the fish grow due to the interacti
 ons of tens of thousands of pigment cells\, making
  agent-based modeling a natural approach for descr
 ibing pattern formation. However\, agent-based mod
 els are stochastic and have many parameters\, so c
 omparing simulated patterns and fish images is oft
 en a qualitative process. Here I will show how to 
 apply methods from topological data analysis to ce
 ll-based\, time-dynamic systems. In this talk\, I 
 will overview our models and present quantitative 
 summaries of messy cell-based patterns forming in 
 time.
