I am a PhD student in the Electrical and Computer Engineering Department at Carnegie Mellon University. I am advised by Prof. Onur Mutlu and Prof. Phil Gibbons. My research interests lie in the general area of computer architecture and systems with a focus on the interaction between programming models, systems, and architectures, specifically in the context of memory systems and throughput-oriented accelerators such as modern GPUs.
