I am a postdoc at the University of Wisconsin-Madison's CS department advised by Prof. Andrea Arpaci-Dusseau and Prof. Remzi Arpaci-Dusseau. I graduated from College of Computing, Georgia Tech, where I was advised by Prof. Karsten Schwan and Prof. Ada Gavrilovska. My thesis explored methods to extend virtual memory support for heterogeneous memory technologies.

I work on Operating Systems, Computer Architecture, Distributed Systems, and High-performance computing (HPC).

I will be joining the CS department @ Rutgers University this Fall (2018) as an Assistant Professor. I am looking for students interested in OS, Computer Architecture, Distributed Systems, and HPC. Please drop me an email (sudarsun.kannan.at.rutgers.edu) if you would like to join my group (and build systems).
