I am a researcher in the VMware Research Group.
I am interested in distributed systems, concurrent algorithms and data structures, systems for non-volatile memory and rack-scale computing.

Previously, I was a PhD student at Brown University, where I worked with Maurice Herlihy and Justin Gottschlich (Intel Labs) on transactional memory and concurrent algorithms for NUMA architectures.
