The systems and networking group at UCSD engages in a wide range of experimental and theoretical research. Our current projects span fault-tolerant networks and systems, high-speed router design, storage system design, network measurement and traffic analysis, peer-to-peer system design, network security, mobile code architectures, high-performance cluster computing, and wireless networking. Our group consists of nine core faculty, four affiliated faculty (in a broad range of areas including security, machine learning and programming languages) and over 50 graduate students and research staff.

April 2— Today Terry Lam successfully defended his dissertation on "Scalable Traffic Management for Data Centers and Logging Devices". Terry continues to swell the UCSD ranks at Google where he is applying his work on network traffic management. Congratulations, Terry!

March 23— A small group explored the fantastic slot canyon in Canyon Sin Nombre for the Winter sysnet hike.

March 21— The announcement was made today that Kevin Webb is a recipient of the 2012–2013 UCSD Barbara and Paul Saltman Excellent Teaching Award for Graduate Students, awarded by the UCSD Academic Senate. Among his other outstanding qualities, Kevin received the award for his tireless efforts and excellence as a teaching assistant for operating systems and distributed systems courses, as an instructor for operating systems, and his leadership as Master TA for CSE. Congratulations, Kevin!

March 11— Congratulations to Alex Rasmussen who defended his dissertation today on "I/O-Efficient Data-Intensive Computing"! After his many world records and contributions while at UCSD, Alex heads to the Bay Area to help Trifacta scale new heights.

January 22— Our own Kevin Fall (Ph.D. 1994) was named the Chief Technology Officer for Carnegie Mellon's Softare Engineering Institute (SEI). See the press release for more details.

January 19— Today Brian Kantor officially becomes a sexagenarian — join us in wishing him a happy 60th birthday! (Coincidentally, it also nearly marks the 27th anniversary of Brian's creating the Network News Transport Protocol (NNTP) in the mid 1980s.)

January 15— Wired Magazine covers our group's work on scale-out data center switching and our joint effort with ECE developing hybrid optical/electrical switches (notably Helios). Cool stuff, but they're two switch generations out date... if they only knew what we're building now!

January 11— NPR's Planet Money covers our Pharmaleaks paper with an interview on Morning Edition and a longer version in their bi-weekly podcast.

December 21— It is with sadness that today we announce the departure of our close colleague George Varghese. After over a decade with us, family needs have taken George to the Bay Area and his new research home at Microsoft Research. We wish him the best and expect to continue to work with him there and with his new colleagues (who we've long been big fans of as well).

Cowles Mountain December 16— For the Fall sysnet hike, twenty-one souls braved wintry conditions (i.e., temps in the 50s) while reaching the summit of Cowles Mountain and were rewarded with panoramic views on San Diego. [All Hikes] Cowles Mountain

December 11— Congrats to Nathan Farrington who defended his thesis today titled, "Optics in Data Center Network Architecture". Nathan is now off to spread UCSD Data Center Networking religion to Facebook. Best of luck Nathan!

November 15— In back-to-back defenses, Xiao Ma also defended his dissertation today on "Diagnosing and Debugging Abnormal Battery Drain on Smartphones" (a condensed version of which will appear in the upcoming NSDI 2013 conference). Congratulations to Xiao, who returns to industry at Pattern Insight, the startup he helped found as a Ph.D. student.

November 15— Congratulations to Ding Yuan who defended his dissertation today on "Improving Failure Diagnosis via Better Design and Analysis of Log Messages"! Ding leaves sunny San Diego for (not as sunny) Toronto, where he begins the next stage of his career as an assistant professor at the University of Toronto.
