Alex Pothen

Alex Pothen is a Professor and Associate Head of the department of Computer Science at Purdue. Alex's research interests are in combinatorial scientific computing (CSC), parallel computing, and bioinformatics algorithms. He has 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.

Combinatorial Scientific Computing 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:
Our Intel Parallel Computing Center award was renewed this year. We have also received funding from the Exascale Computing Project of the Department of Energy for our work on Exascale graph algorithms.
Arif Khan defended his PhD thesis on Computing b-Matching and b-Edge covers in parallel via approximation algorithms in June. Thesis Abstract (PDF)
He will be joining Pacific Northwest National Lab as a staff scientist. Arif was jointly awarded the John R. Rice Fellowship in 2017.

Mu Wang defended his PhD thesis on the Higher Order Reverse Mode in Algorithmic Differentiation in April. Thesis Abstract (PDF)
Mu was awarded the inaugual John R. Rice Fellowship in 2016. Mu has joined Google Corporation in Seattle, WA.

My paper with Yu-Hong Yeung on AMPS, an augmented systems solver for principal submatrix updates with an application to electric power grids, has been accepted at SIAM Journal on Scientific Computing. Here is a Preprint. We also presented simulations of eye surgery at SIGGraph 2016. You can see a video presentation here.

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