DESCRIPTION:Prof. Jörn Dunkel\, Department of Mathematics\, Massachusetts
  Institute of Technology (MIT)\nAbstract:\nBacteria are among the most abu
 ndant forms of life on Earth and play important roles in various biologica
 l\, ecological and industrial processes. In this talk\, I will summarize o
 ur recent efforts to understand better the essential physical mechanisms a
 nd forces that govern individual and collective bacterial dynamics. After 
 looking at the hydrodynamic flow fields generated by individual bacteria [
 1]\, we will demonstrate how collective bacterial swimming in dense suspen
 sions [2] can be controlled through suitably designed microfluidic structu
 res [3]. In the second part\, we will discuss how recent advances in micro
 scopy techniques enable the study of bacterial swarming [4] and biofilm fo
 rmation [5] at single-cell resolution over an enormous range of length and
  time scales -- and which theoretical challenges and opportunities arise f
 rom this unprecedented wealth of data.\n \n[1] Drescher et al\, PNAS 108(

 ical Applied Mathematics at MIT. He studied Physics (2004) and Mathematics
  (2005) at the Humboldt University Berlin\, and completed his PhD at the U
 niversity of Augsburg (2008). After two years of postdoctoral research at 
 the Rudolf-Peierls Centre for Theoretical Physics in the University of Oxf
 ord\, he spent three years as a Research Associate at DAMTP in the Univers
 ity of Cambridge. Working at the intersection of statistical and biologica
 l physics\, Jörn's current research focuses on how physical properties of
  individual cells or microorganisms determine self-organization\, developm
 ent and biological function in multicellular systems. To this end\, his gr
 oup is developing and investigating mathematical models that describe dyna
 mical behavior and structure formation in active and soft matter. Jörn wa
 s elected to a Junior Research Fellowship in Physics at Mansfield College\
 , University of Oxford in 2008\, and was named Research Fellow at Murray E
 dwards College\, University of Cambridge in 2011. He is the recipient of t
 he 2011 Gustav Hertz Prize of the German Physical Society.  Jörn was awa
 rded an Alfred P Sloan Research Fellowship in 2015 and received a Complex 
 Systems Scholar Award from the James S. McDonnell Foundation in 2016.
