Professional Employment

Xinliang Xu received his B.S. in physics from Tsinghua University in 2002.  Then he moved to Department of Physics at University of Chicago, where he obtained his Ph.D. in 2007.  He was then appointed as a postdoctoral associate at James Franck Institute from 2009 to 2011, after which he moved to MIT chemistry as a postdoctoral fellow.  He joined Beijing Computational Science Research Center as an assistant professor in the Complex System Division in September 2014.

Research Interests

Our group studies soft matter materials, broadly defined, through theoretical modeling and computer simulations.  In close collaboration with experimentalists, we are working on a wide range of systems including colloidal suspensions, active bacterial suspensions, and biological molecules such as DNA.  Through efforts in relating the diverse properties displayed to the underlying structures, our research tries to better understand the basic principles of statistical physics, especially those for systems far from equilibrium.
