Research
My research interests include computer systems and networking with an emphasis
on network security, as well as the application of machine learning to
problems in security. Currently, I am exploring the synthesis of systems and
large-scale machine learning techniques to enable reliable decision making
over big data.

In a nutshell...
I am currently a software engineer in the security group at Google.
From 2010--2012, I was a postdoc in the Computer Science
Division at UC Berkeley. I am
supervised by Michael Jordan
and am working closely with Ion
Stoica and Michael
Franklin as part of the AMPLab.
From 2004-2010, I was a PhD student advised by Stefan Savage and Geoff Voelker (Systems and Networking), as
well as by Lawrence Saul (Artificial Intelligence) in the Department of Computer Science and
Engineering at UCSD. From 2001-2004,
I was an undergrad at the University of Maryland, College Park, where I earned
my bachelor degrees in Computer Science and Mathematics.
