About Me

I graduated with a PhD from UIUC, where I was fortunate to be advised by Brighten Godfrey. My thesis looked at fundamental techniques to diagnose failures in networked systems. I am currently a postdoc at Conviva with the inimitable Vyas Sekar, working on failure diagnosis for quality of service issues in distributed applications.

I am broadly interested in networked and distributed systems, and also like to think about algorithms.

Projects: Murphy, TraceWeaver, Flock, DRing, Parsort

My co-pilot.
