Alex Pothen

Alex Pothen is a Professor of Computer Science at Purdue. Alex's research interests are in combinatorial scientific computing (CSC), parallel computing, and bioinformatics algorithms. He served as the Director of the CSCAPES Institute, a pioneering research institute in CSC during 2006-2012, and also as the Director of the Computing Research Institute at Purdue during 2008-2010.

CSC is an interdisciplinary research area where discrete mathematics and algorithms are applied to combinatorial problems from Computational Science and Engineering. CSC links scientific computing to algorithmic computer science. More information about the CSC research community and the biennial SIAM Workshops on CSC are available here.

Recent news from my research group:
Mu Wang defends his PhD thesis on the Higher Order Reverse Mode in Algorithmic Differentiation in April. Thesis Abstract (PDF file)
Two of our papers have been published in the inaugural SIAM Proceedings on CSC. Here is the paper on algorithms for b-Edgecover; and here is the paper on combinatorial aspects of Hessian computation in Algorithmic Differentiation.
SIAM CSE, Atlanta, Feb. 2017 I organized a minisymposium on Algorithmic Differentiation where Mu Wang presented on the higher order reverse mode AD algorithm, and Arif Khan talked about parallel b-Matching and b-Edge cover algorithms in a Mini on Dynamic Graphs.
AD 2016, Oxford, Sep. 2016 Our group gave three talks at this conference.
Yu-Hong Yeung presented simulations of eye surgery at SIGGraph 2016.
Arif Khan presented scalable b-Matching algorithms at Supercomputing 2016. He was jointly awarded the 2017 John R. Rice Fellowship in CSE.

Our research is supported by grants from NSF (Algorithms in the Field), Department of Energy (Exascale Computation Project, Applied Mathematics), and Intel (Parallel Computing Center). More exciting news at the column on the right.
