CURRENT TEACHING: This Fall, I will teach:
Dr. Shang-Hua Teng has twice won the prestigious
Gödel Prize in theoretical computer science,
first in 2008, for developing the theory of smoothed analysis ,
and then in 2015, for designing the
groundbreaking nearly-linear time Laplacian solver for
Both are joint work with Dan Spielman of Yale ---
his long-time collaborator.
Smoothed analysis is fundamental for
modeling and analyzing practical algorithms,
and the Laplacian paradigm
has since led to several
breakthroughs in network analysis, matrix computation, and optimization.
Citing him as, ``one of the most original theoretical computer
scientists in the world'', the Simons Foundation
named Teng a 2014 Simons Investigator, for
pursuing long-term curiosity-driven fundamental research.
He and his collaborators also received
the best paper award at ACM Symposium on
Theory of Computing (STOC) for what's considered to be the
``first improvement in 10 years'' of a fundamental optimization problem
--- the computation of maximum flows and minimum cuts
in a network.
In addition, he is known for his joint work with Xi Chen and Xiaotie
Deng that characterized the complexity for computing an approximate Nash
equilibrium in game theory, and his joint papers on market equilibria
in computational economics.
He and his collaborators also
pioneered the development of well-shaped Dalaunay
meshing algorithms for arbitrary three-dimensional geometric domains,
a long-term open problem in numerical simulation, also
a fundamental problem in computer graphics.
Software based on this development was used at
the University of Illinois for the simulation of advanced rockets.
Teng is also
interested in mathematical board games.
With his former Ph.D. student Kyle Burke, he designed and
analyzed a game called Atropos ,
which is played on the Sperner's triangle and based on the beautiful,
celebrated Sperner's Lemma.
In 2000 at UIUC, Teng was named on the List of Teachers Ranked as
Excellent by Their Students for his class,
``Network Security and Cryptography''.
He has worked and consulted for Microsoft Research, Akamai, IBM
Almaden Research Center, Intel Corporation, Xerox PARC,
and NASA Ames Research Center, for which he received
fifteen patents for his work on
compiler optimization, Internet technology, and social network.
