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

October 6— Today, the accepted paper list for the 2021 ACM Internet Measurement Conference was announced. Of the 55 papers to appear, more than 1 in 5 have UC San Diego authors -- a record (at least for us!) Seven were submitted by authors in the systems and networking group (and appear on this page), three had CAIDA authors, 1 was co-authored by UCSD undergrad Katherine Izhikevich (along with UCSD alumnus Liz Izhikevich), and one by (then CMU undergraduate and now sysnet Ph.D. student) Rukshani Athapathu. In addition, another four papers were written by UCSD Ph.D. or postdoc alumnus (Krishna Gummadi, Damon Mccoy and Yoshi Kohno). A very productive year! Congrats everyone and, in particular, congrats to our UCSD authors: Gautam Akiwate, Rukshani Athapathu, kc Claffy, Alberto Dainotti, Alexander Gamero-Garrido, Katherine Izhikevich, Dhananjay Jagtap, Enze Liu, Alexander Marder, Ramakrishna Padmanabhan, Ariana Mirian, Ricky Mok, Audrey Randall, Stefan Savage, Aaron Schulman, Alex C. Snoeren, Alisha Ukani, Geoffrey M. Voelker, Huanlei Wu, Alex Yen, Zesen Zhang, and Hongyu Zou.

Golden Goose Award September 22— Congratulations to the all-star team of Steve Checkoway, Damon McCoy, Daniel Anderson, Hovav Shacham, Stefan Savage, and the late Brian Kantor, and their University of Washington collaborators Karl Koscher, Alexei Czeskis, Franzi Roesner, Shwetak Patel, and Yoshi Kohno! Their landmark work on security vulnerabilities in modern automobiles was just awarded a 2021 Golden Goose Award from the American Association for the Advancement of Science. The award honors research for which the results were unforeseen at the outset, but which ultimately led to major breakthroughs that have had significant societal impact. Read about the The Fast and the Curious and watch the wonderful video! As Charlize Theron famously quipped, "Hack them all". Indeed, Charlize. Indeed. Autosec

Alex Gamero-Garrido August 18— Congrats to Alex Gamero-Garrido, who defended his dissertation today on "Transit Influence of Autonomous Systems: Country-Specific Exposure of Internet Traffic". Alex will be starting as a Future Faculty Fellow (postdoc) at Northeastern University this fall.

July 14— Congrats to Gautam Akiwate and his collaborators for receiving the Best Paper award at the 2021 IEEE/IFP TMA Conference for their paper on characterizing Anycast adoption in DNS. Gautam Akiwate

Priyal Suneja June 12— Congratulations to Priyal Suneja for receiving the CSE Department Student Award for Excellence for 2021! This award follows her other awards for Excellence in Service & Leadership in 2020 and Excellence in Contributions to Diversity in 2019, not to mention all of her leadership efforts for Women in Computing. Thanks Priyal for all of your hard work and devotion to everyone in the department! We wish you the best as you continue your journey in the Ph.D. program at the University of Washington.

June 2— The awards keep on rolling in! Today it was announced that Stefan Savage has received the 2021 Academic Senate Distinguished Research Award, which is awarded "for the ground-breaking research conducted by members of the UCSD faculty". This particular award comes with work, however: Stefan has to give a university-wide lecture on his research. Congratulations Stefan, and we all look forward to your lecture! Stefan Savage

AAAS April 22— Congratulations to Stefan Savage for being elected to the American Academy of Arts & Sciences! The Academy celebrates excellence across every field of human endeavor "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." Being elected to the Academy is a tremendous honor and outstanding achievement. Way to go, Stefan! Stefan Savage

Audrey Randall January 5— Congratulations to Audrey Randall (and her co-authors) for being named as a winner of the Internet Research Task Force's Applied Networking Research Prize for her work on the Trufflehunter DNS inference system.
