July 8— Congrats to Sam Crow who successfully defended his thesis today, "Security Testing Tools for Complex Cyber-Physical Systems". No doubt the only Ph.D. we've seen that involved significant chunks of a 737 in their home. Congrats!

June 1— Congrats to Gautam Akiwate who successfully defended his thesis today, "Identifying DNS Infrastructure Hijacks using Large Scale Measurements". Gautam will be starting a Postdoc with Zakir Durumeric at Stanford. Gautam has been a force for good in the department for longer than he will admit -- supporting Chez Bob, the holiday parties, sysnet outings, etc -- and we will all miss him.

May 23— Eleven years ago, UCSD alumns Kirill Levchenko, Andreas Pitsillidis, Neha Chachra, Brandon Enright, Tristan Halvorson, Chris Kanich, He Liu, and Damon McCoy, along with UCSD faculty Geoff Voelker, Stefan Savage and their colleagues from Berkeley and Budapest, Mark Felegyhazi, Chris Grier, Christian Kreibich, Nicholas Weaver and Vern Paxson, published a comprehensive analysis of the spam criminal value chain. Today that paper, Click Trajectories: End-to-End Analysis of the Spam Value Chain and its impact was celebrated with the Test-of-Time award, presented at the 2022 IEEE Security and Privacy conference. Congrats all!

April 13— Fourteen years after publishing their 2008 ASPLOS paper "Learning from Mistakes -- A Comprehensive Study on Real World Concurrency Bug Characteristics", YY Zhou and her co-authors have received this year's "Most Influential Paper" award from ASPLOS for this work. Congrats to YY, Shan, Soyeon and Eunsoo!

April 4— The results of this year's NSF Graduate Research Fellowship Program are out and we are delighted to share that Alisha Ukani was among the winners. Congrats Alisha!

March 4— Back-to-back defenders! Congratulations also to Yizhou Shan, who defended his dissertation today on "Distributing and Disaggregating Resources in Data Centers". Yizhou will be starting as Research Scientist at Huawei Cloud this spring.

March 3— Congratulations to Lixiang Ao, who defended his dissertation today on "Framework and Platform Support for General Purpose Serverless Computing". Lixiang will be starting at Databricks this spring.

February 2— Congratulations to Stewart Grant who is one of the 2022 Meta PhD Research Fellowship winners. Stew is one of only two students selected in networking among the 37 fellows. Congrats, Stew!

January 24— More great news – Stefan Savage received a Diamond Award from the University of Washington School of Engineering, an award which honors outstanding alumni who have made significant contributions to the field of engineering. Stefan received the Distinguished Achievement in Academia award for his signature style of work that "challenges traditional investigation methods and redefines academic approaches to network security, privacy and reliability". Congratulations Stefan!

January 10— Congratulations to Gautam Akiwate (and his co-authors) for being named as a winner of the Internet Research Task Force's Applied Networking Research Prize for his work characterizing a domain hijacking risk that is an accidental byproduct of undocumented operational practices between domain registrars and registries. Gautam's award marks the second year in a row that the group has received the prize (Audrey Randall received it last year). Let's keep the streak going!

December 11— Its been a long road, but after 14yrs, a bunch of jobs, founding and building up AttackIQ, the pandemic gave prodigal member Stephan Chenette the pause to finish his Masters with his master's thesis, "An Analysis Of Judgment Variability Amongst Cybersecurity Participants When Asked To Forecast Cybersecurity-related Events". A nice bit of work and proof that you can go home again. Congrats Stephan!

October 8— We just learned that our own Alisha Ukani has been named to this year's class of UCSD ACRS Foundation Fellows. Congrats Alisha!

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.

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.
