About me

I’m a second-year PhD student at the University of Washington Paul G. Allen School of Computer Science & Engineering. I work in the Programming Languages and Software Engineering group, and am advised by Rastislav Bodik.

My overall research focus is on using program synthesis to improve low-level performance, especially of numerical code and programs used in high-performance computing. Currently, I’m developing abstract dynamic programming, a new synthesis technique that can be used to accelerate enumerative searches through a space of programs, and applying it to the problem of automatically filling in the details of numeric kernels on GPUs and other similar hardware. I’m also investigating using approximated dynamic programming for finding optimal patterns of loop tilings and memory movements to surround numerical kernels.

News

2019-06-22 I’ll be attending PLDI 2019 and the ARRAY workshop, although I’m not presenting anything this year. If you’re interested in meeting up, please send me an email.
2019-03-22 I will be attending the CRA Grad Cohort Workshop for Underrepresented Minorities and People with Disabilities and presenting my poster on “Synthesizing data movement in GPU kernels using abstract dynamic programming”
