I am a senior researcher in the Software-HARdware Codesign (SHARC) team at Microsoft Research Redmond, after spending time in the Intelligent Networked Systems group (previously Office of the CTO, Azure for Operators). I received a Ph.D. in Computer and Information Science from University of Pennsylvania, where I was fortunate to be advised by Vincent Liu. I received an M.Sc. in Electrical Engineering from KTH Royal Institute of Technology, Sweden.

My work lies in the broad, interdisciplinary areas of systems and networking. I enjoy understanding and working near tangible hardware (e.g., networking devices, memory subsystems, and heterogeneous accelerators), with a focus on developing hardware-aware techniques in software systems for modern applications.
