I am a Professor of Computer Science at UC Santa Barbara. My research covers a range of topics from large-distributed networks and systems, HCI, security and privacy, and wireless / mobile systems, mostly from a data-driven perspective. My current projects are focused on three areas: data-driven models of user behavior/interactions, security of online and mobile communities, and wireless systems and protocols. My work targets a range of top conferences, including WWW/IMC, Mobicom/SIGCOMM/NSDI, UsenixSecurity/NDSS/S&P, CHI/CSCW. Here's a wordle of my paper abstracts from 2013-early 2015.

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 an ACM Distinguished Scientist, a recipient of the National Science Foundation's CAREER award (2005), MIT Tech Review's TR-35 Award (Young Innovators Under 35) (2006), IEEE Internet Technical Committee's Early Career Award (2014), and one of ComputerWorld's Top 40 Technology Innovators under 40. My papers have a bit more than 20,000 citations and an H-index of 52.

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 ("Top Writer" 2014-2016). 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 do not have spots for visiting students or postdocs. Please do not send me unsolicited email about visiting student or postdoc applications; due to the volume of these emails, I will be unable to reply to them individually.

UCSB Undergraduates interested in research?
I generally advise 1-3 undergraduates in my lab in active research. Right now we have Kevin Malta and Megan McQueen 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).
