This page, circa 2011

I am a Professor of Computer Science at UC Santa Barbara. My research covers a range of topics from large-distributed networks and systems, data mining and modeling, security and privacy, and wireless / mobile systems. My current projects are focused on three areas: querying, modeling and mining massive graphs, security of social and online communities, and wireless systems and protocols. Here's a wordle of my paper abstracts from 2009-2012.

Together with Prof. Heather Zheng, I co-direct the SAND Lab (Systems, Algorithms, Networking and Data) at UCSB. We also collaborate with other research groups in the department, including the Security Lab, the Database group, the Mobility Management and Networking (MOMENT) lab, and groups in the Communications, ECE, and Statistics departments. I received my PhD in Computer Science from UC Berkeley in 2004, where I was advised by John Kubiatowicz and Anthony Joseph, and created the Tapestry distributed hash table (dissertation). I received my MS from Berkeley in 2000, and my BS in computer science from Yale in 1997. I am a recipient of the National Science Foundation's CAREER award (2005), MIT Tech Review's TR-35 Award (Young Innovators Under 35) (2006), and one of ComputerWorld's Top 40 Technology Innovators under 40. I have a bit more than 17,000 citations and an H-index of 45.

I'm looking for bright PhD students!!
We've got too many cool projects, and not enough driven/passionate students to drive all of them! Email me if you're interested in working with me, and like to have fun in your research projects. But before you do, please read a FAQ, and a note on why you should choose UCSB. I am also very active on Quora (a "top-answerer"). You can read about my views on grad students (1, 2, 3), grad admissions (1, 2, 3), research (1, 2), and grants (1)
Update: We had an unexpectedly high take rate this year (6/7), so we will likely not be recruiting for 2015.

UCSB Undergraduates interested in research?
I generally advise 1-3 undergraduates in my lab in active research. Right now we have Allen Chang and Chris Nelson in the lab. The best way to join my lab as an undergrad is to take and do well in my courses, CS176B (network programming), CS170 (Operating Systems), or CS276 (graduate networking).
