Xiao-Lun Wu received his Ph.D. from Cornell University in physics and is an associate professor at the University of Pittsburgh. His research focuses on the long-standing problem of the effect of spatial disorder on critical fluctuations of Ising-like systems, particularly fluid flow and turbulence in thin, free-standing liquid films as well as particle diffusion and thermal convection. Some of his recent research includes: hydrodynamics in free-standing liquid films, nucleation and chiral symmetry breaking under hydrodynamic flows, structure and dynamics in a glass forming system, internal modes of macromolecules and critical fluctuations in porous media. Dr. Wu has been an invited speaker at Los Alamos National Laboratory, the Aspen Center for Physics, Ford Motor Company and numerous universities and society meetings. He is a member of the American Physical Society and the Materials Research Society.
