My research is on
combinatorial scientific computing, which deals with combinatorial problems
arising in applications and algorithms of scientific computing. My
early work was on traditional applications of combinatorial scientific
computing such as sparse matrix computations and parallel computing, where
the combinatorial algorithms work on the back stage to play an enabling
role. Recently, I have started looking at areas where combinatorial
problems are directly associated with scientific and engineering goals.
My current
projects are vulnerability analysis of the electric power grid,
interconnection networks for peta-scale systems, energy efficient disk
systems, and supernova spectra analysis.
I work at the High Performance Computing Research Department
of Lawrence Berkeley National Laboratory(LBNL).
Before joining LBNL, I was at the Department
of Computer Science at University of University of Illinois at Urbana Champaign,
where I received my PhD. During my PhD. studies I have frequently
visited Sandia National Laboratories
at New Mexico, which had a significant impact on my research. I also have
MSc. and BSc. degrees in computer
engineering from Bilkent
University in Turkey.
Announcements
·
I
will be at the CSC workshop
at Santa Fe, June 10-13 2008.
·
I
am planning to attend the Dagstuhl seminar on combinatorial scientific
computing from February 1-6, 2009, in Saarbrucken, Germany.
·
I have been recently elected Secretary of SIAM Activity
Groups of Supercomputing, for which I will be serving until December 31,
2009.
· I am on the
program committee of CSC
2009, the SIAM Workshop on Combinatorial Scientific Computing. The workshop
will focus on combinatorial
problems that arise in scientific computing. The 2009 CSC workshop will be
held in October 2009 in Monterey,California, in conjunction with the SIAM
Linear Algebra Conference.The tentative dates for the workshop are October
29-31 (and October26-29 for the Linear Algebra Conference), but the hotel
arrangements have not yet been finalized, so the dates may move a bit.
· We finished the
review process for IPDPS 08, which will
be held in Miami, Florida on April 14-18, 2008. This is IEEE’s premier
conference in parallel and distributed computing, and the quality of the papers
matched the reputation of the conference.
