Professor Guo received his B.S. from Peking University in 1987. He received
his Ph.D in Mathematics from Brown
University in 1993. He was a Courant Instructor at the Courant Institute of Mathematical Sciences
for 1993-95. He joined the faculty of the Division of Applied Mathematics at
Brown University as an Assistant Professor in September 1995. He was an Assistant Professor
at Princeton University
for 1996-97. His professional awards include an Honorable Mention in SIAM Student Paper Competition in
1992, an A. P. Sloan Dissertation Fellowship in 1993, an NSF Postdoctoral Fellowship for 1995-98.
Professor Guo is an A. P. Sloan Research Fellow for 1998-2000. He was named a Manning Assistant
Professor at Brown for 1998 to 1999, and was promoted to an Associate Professor in 1999 and then Professor
in 2004. Professor Guo's current research is concerned with
partial differential equations and their applications, such as kinetic and fluid models for plasma physics, vortices in classical field theory (superconductivity and superfluidity), as well as stability problems in stellar dynamics.
