Howdy! I'm a 5th-year Ph.D. student at Rice CS, working with Dr. Scott Rixner and Dr. Alan L. Cox, on computer architecture and systems. Thrusts: hardware acceleration, FPGAs, performance optimizations, computer arithmetic.

Prior to Rice, I spent two wonderful years at University of Rochester CS (M.S.). I had great fun working on hardware acceleration with Dr. Yuhao Zhu, and I was fortunate to be instructed by Dr. Sreepathi Pai.
