I am no longer at Yale; please see my personal website instead.

I am an Associate Professor (pre-tenure) in the Department of Computer Science at Yale University. I work in the union of distributed systems, storage, and networking. I was previously at VMware Research until May 2015, and before that at Microsoft Research Silicon Valley until Nov 2014. I got my PhD at Cornell University in 2009 while working with Ken Birman on reliable communication protocols for data centers.

At Yale, I am a member of the Computer Systems Lab.

My work is funded by an NSF AitF grant, Facebook Faculty Awards (2015 and 2016), and a VMWare Early Career Faculty Grant (2017).
