In spring 2010, I graduated from the PhD program in computer science at the University of California Berkeley. My advisor was Prof. James Demmel. I'm now a postdoc at Sandia National Laboratories. My research involves new computational kernels and algorithms for solving sparse linear systems and eigenvalue problems, that perform better than existing algorithms by moving less data (sometimes at the cost of extra computation). In general, I am interested in the relationship between numerical accuracy and performance. I was also a teaching assistant in fall 2007 for a new undergraduate course on parallel programming.

"On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
