SHORT BIO: 
ShangHua Teng is the Seeley G. Mudd Professor at the
Computer Science Department, Viterbi School of Engineering, USC, where
he was a former chair (20092012). He
received a dual B.S. degree in computer science and electrical
engineering from Shanghai Jiao Tong University in 1985, M.S. degree in
computer science from USC in 1988, and Ph.D. degree in computer
science from Carnegie Mellon University (CMU) in 1991. He was an
instructor in the Department of Mathematics of MIT and professor in
the Computer Science Departments of Boston University, the University
of Minnesota and UIUC. He has worked and consulted for Microsoft
Research, Akamai, IBM Almaden Research Center, Intel Corporation,
Xerox PARC, Cray Research/SGI, Thinking Machines Corporation, and NASA
Ames Research Center. He has received more than ten US Patents for his
work on compiler optimization, Internet technology, and social network
analysis.
Teng's main research is in algorithm design, analysis, and applications. He and coauthor Dan Spielman received the Gödel Prize (2008) and Fulkerson Prize (2009) for developing Smoothed Analysis. His recent work addresses Spectral Graph Theory & the Laplacian Paradigm and its applications to maximum flows, for which he and coauthors Paul Christiano, Jon Kelner, Aleksander Madry, and Dan Spielman received the best paper award at ACM STOC 2011. In addition, he has conducted research in Algorithmic Game Theory, where he is known for his joint paper with Xi Chen and Xiaotie Deng for resolving the complexity for computing an approximate Nash equilibrium and his joint papers on market equilibria. Teng is also interested in mathematical board games. Kyle Burke, his former Ph.D. student, and he designed & analyzed a game called Atropos, which is played on the Sperner's triangle and based on the beautiful, celebrated Sperner's Lemma. Teng's past research interests include scientific computing, Internet algorithms, computational geometry, percolation theory, compiler optimization, parallel algorithms, cryptography, computer graphics and threedimensional mesh generation, where he had obtained fundamental results in geometric separators, wellshaped Delaunay meshing, spectral graph partition, Nbody simulation, and robust statistics. Teng is an ACM Fellow, Alfred P. Sloan Fellow, winner of Senior Xerox Award for Outstanding Faculty Research (UIUC), and NSF CAREER Award.
