About Me

I am a PhD student in Electrical Engineering at Columbia University, working with Prof. Tanvir Ahmed Khan. My research focuses on profile guided optimization, optimizing power management systems, and data provenance for database systems. I am particularly interested in optimizing the performance and power efficiency of GPUs and other accelerators, both from a compiler perspective and power management. My ultimate goal is to create a generalized system capable of optimizing any combination of heterogeneous systems for any application.
