I am a senior researcher in the Software HARdware Codesign (SHARC) team at Microsoft
Research Redmond, after spending about a year in the
Intelligent
Networked Systems group (previously Office of the
CTO, Azure for Operators).
I earned my Ph.D. in Computer and Information Science at University of Pennsylvania, where I was fortunate to be advised by Vincent Liu.
Prior to Penn, I received an M.Sc. in Electrical Engineering from KTH Royal Institute of Technology and sampled random experiences in various contexts
of networked systems.
My work is in the broad, interdisciplinary areas of systems and networking. Much of it involves the efficient co-design of software and hardware for modern data center tasks, around hardware such as memory subsystems and networking ASICs. I am particularly drawn to the tangible aspects of the domain.
