shri

I am a staff scientist in the Energy Systems Division at Argonne National Laboratory. Prior to this position, I was a post-doctoral appointee from September 2011 – January 2014 and a pre-doctoral appointee from September 2009 – August 2011 in the Mathematics and Computer Science Division. I received a Ph.D. degree from Illinois Institute of Technology in 2011. Since 2009, I’ve been involved in the development of the high performance library PETSc.
