Alex Pothen's research interests are in combinatorial scientific computing
(CSC), an area where combinatorial problems in scientific
computing are formulated, and algorithms for solving them are designed,
analyzed and implemented. He has helped to organize the CSC research
community by co-chairing the first two international workshops on CSC
held at San Francisco (2004) and Toulouse, France (2005).
He is also chair of the 2007 CSC workshop
to be held together with the SIAM Conference on Computational Science.
Professor Pothen's current research projects include:
the development of specialized graph coloring algorithms for
automatic differentiation, a technology for computing derivatives in
nonlinear optimization and differential equations;
the design of approximation and exact algorithms for weighted matchings
in graphs, with application to the solution of ``saddle point
problems'' in optimization, fluid dynamics, and soft-tissue modeling;
and the construction of protein interaction networks via literature
mining and knowledge discovery in such networks.
Professor Pothen has published more than 60 papers, including in 2005
a 77-pages article in SIAM Review, the journal with the highest
impact factor among the highly regarded SIAM journals.
He has directed ten PhD students and advised five post-doctoral fellows.
Since 1995, he has received more than $7 Million in research
support from the National Science Foundation, Department of Energy,
Department of Education, IBM, Lawrence Livermore National Laboratory, and
the Office of Research at ODU.
