ABOUT ME

I am currently pursuing my PhD in Computer Science and Engineering at The Pennsylvania State University. I am a member of High Performance Computing Lab where I work with my advisors Dr. Chita R. Das. and Dr. Mahmut T. Kandemir. I also collaborate with Dr. Onur Mutlu. My current research focuses on designing high performance energy-efficient heterogeneous GPU architectures.

CURRENT RESEARCH

I am currently working on understanding the research issues and opportunities involved in processing in memory in GPUs. Specifically, I am trying to understand the issues of "which" computations to offload to the PIM processors, and "how" to co-locate the computations and data to minimize the data movements in a GPU system while improving performance.
