摘 要:

 Self-organization is commonly found in biological systems, such as embryogenesis, organ development, and collective motion of populations.  Unlike animals and insects, bacteria do not have complex sensory systems, yet they are able to display self-organization at various length scales either due to rudimentary chemical signaling or due to purely physical interactions.  In this talk I will introduce several remarkable examples of bacterial self-organization and collective motion, and will discuss how bacterial communities may benefit from these processes to overcome the limit of diffusion for efficient long-range material transport.  The findings are relevant to biofouling, pathogenesis, as well as self-organization in general active matter systems.


   Dr. Yilin WU obtained his B.S. in Physics from the University of Science and Technology of China in 2004 and Ph.D. in Physics from University of Notre Dame in 2009.  After doing postdoctoral research with Howard C. Berg at Rowland Institute of Harvard University, he joined the Department Physics of the Chinese University of Hong Kong as an Assistant Professor in 2012.  His research interest is in biophysics and quantitative biology, with a focus on bacterial motility and behavior in multicellular systems.
