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.

Brian Kantor November 21— It is with great sadness that we learned today that Brian Kantor has passed away. Brian worked in the systems and networking group for the last decade before his retirement in 2018. You'll see his name on the automotive and voting security papers we published and the reality is that much of the work we did benefited from his ability to pull a rabbit out of the hat when we needed one. But CSE was only a small part of his time here at UCSD. Brian was truly an institution and had been at UCSD for 47 years. He was the University postmaster, he ran the name servers and he helped run network infrastructure. For those old enough to remember rlogin — he wrote the protocol. Ditto for the NNTP protocol that Netnews was based on. He was a nationally known ham radio operator and also co-founded and managed AMPRnet (the amateur radio packet network) which also became a critical research resource both here in CSE and at CAIDA. Brian was a unique personality and didn't naturally fit within bureaucracies, but he was eager to teach to those who wanted to learn, had a sharp wit and was an implacable advocate for doing the right thing. We were lucky to have had the time we had with him.

September 27kc claffy was named one of this year's 11 inductees into the Internet Hall of Fame! While formally recognized for her own "pioneering work in Internet analysis and measurement", we all know that the datasets CAIDA (which she founded in 1997 and directs to this day) produces underly a large fraction of not only SysNet's publication list, but the networking community's at large. We’re not worthy! kc claffy

Zhaomo Yang September 5— Congrats to Zhaomo Yang, who defended his dissertation today on "Compilers and Software Security: Opportunities and Challenges". He will be joining Google shortly.

August 18— Today, at Crypto 2019, Nadia Heninger was named the recipient of the CRA-W's Borg Early Career Award! Congrats Nadia! Nadia Heninger

Grant Ho August 14— Congrats to Geoff Voelker, Stefan Savage and their Berkeley colleagues (notably Ph.D. student Grant Ho who, was the sole student on this effort) for winning the Distinguished Paper Award at USENIX Security for their paper, Detecting and Characterizing Lateral Phishing at Scale.

June 14Alex Gamero-Garrido has been awarded a Microsoft Dissertation Grant to support his work identifying nations whose Internet connectivity is particularly vulnerable to censorship, inspection, or disruption by foreign countries. Congratulations Alex! Alex Gamero-Garrido

Ariana Mirian June 7— Congratulations to Ariana Mirian for receiving the 2019 CSE Doctoral Award for Excellence in Service/Leadership, together with Ailie Fraser. Thank you for your dedication, Ariana!

May 24— Congratulations to Louis Dekoven and Brown Farinholt for defending their respective dissertations today. This double header started with Brown's "Understanding the Remote Access Trojan malware ecosystem through the lens of the infamous DarkComet RAT", broke for lunch, and then concluded with Louis, "Addressing Device Compromise from the Perspective of Large Organizations". This is not their last party together however, as both are eventually headed to a new group at Facebook's DC office. Louis DeKoven and Brown Farinholt
