About

I recently graduated with a PhD degree from the Computer Science Department at CMU, and I now work at NVIDIA Research. My research focuses on operating systems and architecture with an emphasis on efficiency, performance and scalability in data centers.

At CMU, I was advised by Professor Dimitrios Skarlatos and part of the CAOS group. I received my bachelor's degree in computer science at Purdue University, and I'm honored to have worked with Professor Pedro Fonseca and Professor Felix Lin.
