I'm at the S* Network Systems Group (SNS) in the Computer Science Dept. I'm a third-year PhD student. I joined Princeton after several years at Mazu Networks (acquired by Riverbed Technology). I'm advised by Prof. Mike Freedman and Prof. David Blei. I received my M.S. in Computer Science from Purdue University.

Research

For recent work and publications please see my CV.

Along with Erik Nordstrom and David Shue, I built the first version of an end-host stack for a service-centric network architecture called Serval.

Since June 2011, I've been working with Prof. David Blei and Prof. Mike Freedman on online learning for overlapping community detection.

Industry experience

At Mazu, I worked on some cool projects:

• A redesign of arena allocation within glibc malloc(), used in Mazu products for several years
• Detecting worm signatures seconds after they spread using fingerprints (PDF)
• Detecting network problems without any thresholds using time series analysis (now part of a commercial product; fun demo here)
• Fast IP lookup for DDoS prevention using k-ary trees in the Linux kernel
