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 eight core faculty, five affiliated faculty (in a broad range of areas including security, machine learning and programming languages) and over 50 graduate students and research staff.

October 06— Last night Yuanyuan Zhou ("YY") was named the 2015 winner of the ACM SIGOPS Mark Weiser Award, named for the legindary leader of Xerox PARC CSL. It is the highest award given by the operating systems community and is selected for "Contributions that are highly creative, innovative, and possibly high-risk, in keeping with the visionary spirit of Mark Weiser". There is no doubt that YY's work is all of these things and we are honored to have her as our friend and colleague. You can read more here.

August 11— It is a Corvette Summer for Ian Foster and Karl Koscher! Today at WOOT 2015 Ian presented his paper, "Fast and Vulnerable: A Story of Telematic Failures", detailing the security vulnerabilities of car insurance dongles, co-authored with Andrew Prudhomme, Karl, and Stefan. WIRED also covered their work in an article today, "Hackers Cut a Corvette's Brakes Via a Common Car Gadget", picturing Karl and Ian. Special thanks to Sid Karin for the use of his Corvette!

June 5— Today the winners of the inaugural CSE Graduate and Undergraduate awards were announced, and we are thrilled that four students in the Sysnet group were recognized with awards: Neha Chachra was awarded the Graduate Award for Service and the Viceroy of Social Hour, Gautam Akiwate was awarded the Graduate Award for Teaching, Jake Maskiewicz was awarded the Undergraduate Award for Teaching, and Louis Dekoven was a runner up for the Viceroy of Social Hour. Congratulations everyone on all of your award-winning efforts!

June 2Keaton Mowery successfully defended his thesis today titled "Beneath the Attack Surface." He'll be heading up north to join Apple, and we wish him the best of luck. Congratulations Keaton! Keaton Mowery

May 30— This year's spring hike was a 14.25-mile journey across the breadth of Palomar Mountain, from the Boucher Fire Lookout in the east to the Observatory in the west. And not to be missed was Historic Scott's Cabin!   (Pics)   (GPS Track)   (All Hikes)

Rishi Kapoor May 26Rishi Kapoor successfully defended his thesis today on "Leveraging the End-host Stack to Meet Data Center Applications Performance Requirements." He just accepted a position at Google working on data center networking. Congratulations Rishi!

May 22Malveeka Tewari successfully defended her thesis today on "Enabling Fine-grained Flow Management in Data Centers". She'll be bringing her talents in developing networked systems to Google in Mountain View starting this summer. Congratulations Malveeka! Malveeka Tewari

Mike Conley May 22Mike Conley successfully defended his thesis today on "Efficient I/O in Next-Generation Clusters". As part of his dissertation research, Mike helped to break numerous world records in sorting data, which is one of the oldest and most common problems in the field. Congratulations Mike!

April 11— This year's winter hike was an 8-mile off-trail rambling loop from Mountain Palm Springs to Indian Valley and back around through Indian Gorge in Anza Borrego, with some bouldering and scrambling up a ridge thrown in for kicks.   (Pics)   (GPS Track)   (All Hikes)

March 16He Liu successfully defended his thesis today on "A High Performance Hybrid ToR for Data Centers". After many a sojourn across systems, security, and networking, Lonnie decided to end his graduate adventure in the data center. (And, yes, he's joining Google.) Congratulations and good luck, Lonnie! He Liu
