DESCRIPTION:Living organisms rely on flows to perform essential functions 
 that range from swimming and feeding in unicellular organisms to mucus cle
 arance in humans. These flows are generated by the inte&shy\;grated activi
 ty of thousands of micrometer scale cilia attached to cell surfaces. Colle
 ctions of cilia exhibit highly complex temporal patterns known as metachro
 nal waves. While patterns of cilia coordination have been observed for dec
 ades\, the mechanisms underlying their formation and their contribution to
  flow generation remain unclear. In my talk I will discuss the advantages 
 of ciliated swimmers as experimental model systems where measurements of t
 he geometric and dynamic properties of cilia arrays and can be readily per
 formed. Performing precise measurements and perturbations of temporal patt
 erning in cilia arrays and flows will enable the identification of the mec
 hanisms underlying pattern formation. This integrated view that seeks to l
 ink cilia dynamics with flow structure will significantly increase our und
 erstanding of the physiology of cilia arrays. Beyond their physiological s
 ignificance\, arrays of cilia provide an accessible experimental platform 
 to explore the physics of multi scale pattern formation.
