I am a postdoctoral researcher at the CS department at the University of Wisconsin-Madison. I work with Prof. Andrea Arpaci-Dusseau and Prof. Remzi Arpaci-Dusseau at the ADSL lab. I currently study OS and application data storage problems.

I was a Ph.D. Student at the College of Computing, Georgia Tech. My thesis explored methods to extend virtual memory support for heterogeneous memory technologies. My advisers were Prof. Karsten Schwan and Prof. Ada Gavrilovska.

I am interested in Operating Systems, Computer Architecture, Storage, Distributed Systems, and Hardware-Software interactions. My Ph.D. thesis and current work have focused on problems at the intersection of hardware and software.

I'm on the research and academic job market! [CV]
