Zhen-Gang Wang received his B.Sc. in Chemistry in 1982 from Beijing (Peking) University, and his Ph.D. in Chemistry in 1987 from the University of Chicago where he worked with Stuart Rice and Karl Freed. He did postdoctoral research first in Exxon Research and Engineering Company, with Sam Safran and Tom Witten, and then at UCLA with Bill Gelbart. Since 1991 he has been on the Chemical Engineering faculty at the California Institute of Technology, where he is currently the Dick and Barbara Dickinson Professor of Chemical Engineering. Wang’s research is the theoretical and computational study of structures, phase behavior, interfacial properties and dynamics of polymers, soft materials, and biophysical systems. His current activities revolve around three main themes: charged systems, including polyelectrolytes, salt-doped polymers, and electric double layers; nucleation or more generally barrier crossing in polymers and soft matter; and nonlinear rheology of polymer gels and entangled polymers. Wang was a recipient of the Henry and Camille Dreyfus New Faculty Award, the Camille Dreyfus Teacher-Scholar Award, and the Alfred P. Sloan Award. He was elected a Fellow of American Physical Society in 2001. In 2008 he was awarded the Richard P. Feynman Prize for Excellence in Teaching at Caltech.
