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.

August 16IMC 2020 paper acceptances are now public and, of the 53 papers accepted, five are from UCSD and another five are from UCSD alumni. Congrats to Gautam Akiwate, Audrey Randall, Enze Liu, Ramakrishna Padmanabhan, Stefan Savage, Geoff Voelker and Aaron Schulman from CSE, Alexander Marder, Alberto Dainotti and kc Claffy from CAIDA, and our alumns (Chris Kanich, Yoshi Kohno, Yuvraj Agarwal, Liz Izhikievich and Damon McCoy). Particular congrats to Gautam who had three papers accepted this round!

Vector June 10— Congrats to Guo "Vector" Li, who defended his dissertation today on "An Empirical Analysis on Threat Intelligence: Data Characteristic and Real-World Uses". Vector will be joining Google to work on cloud security with our old collaborator, Chris Grier.

May 22— Congrats to Moein Khazraee! Moein defended his dissertation, "Reducing Development Cost for Customized Hardware Accleration in the Cloud Infrastructure", today and will soon start his postdoc at MIT. Moein

HASH(0x5595a3b43838) May 18— Congratulations to the all-star team of Steve Checkoway, Damon McCoy, Danny 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 study of the vulnerability of modern automobiles was awarded the 2020 IEEE Security & Privacy Test of Time Award. Read more about their efforts around their seminal work. HASH(0x5595a3b43490)

RSA-250 cryptographic challenge March 12— Congratulations to Nadia Heninger and her collaborators for setting a new factoring record by being the first to factor the RSA-250 prime in the RSA factoring challenge.

February 25— Congratulations to Mohammad Al-Fares, Sivasankar Radhakrishnan, Barath Raghavan, Nelson Huang and Amin Vahdat for winning the the NSDI Test-of-Time award! Their paper, Hedera: Dynamic Flow Schedule for Data Center Networks, was published ten years ago and is part of the group's legacy of leading data center networking research. Ten years later, the authors are doing well. Mohammad is at Google along with Engineering Fellow and Vice President Amin Vahdat, Siva is at Forward Networks and Barath is on the faculty at USC. UCSD has quite a history with this award and four out of the last five years have seen NSDI Test-of-Time awards given to papers with one or more UCSD authors. Hedera

Yiying Zhang February 7— Congratulations to Yiying Zhang who was awarded a VMware Early Career Faculty Grant!

January 8— Each year, the Center for Networked Systems (CNS) awards the Alan Turing Memorial Scholarship to one or more students for their academic commitment, particularly in networked systems, and their ongoing support for the LGBTQ community. This year the scholarship was awarded to both Giselle Mejia and another undergraduate who wishes to remain anonymous. Congrats to both winners! Alan Turing Memorial Scholarship

Ariana Mirian Inclusive Excellence Award December 16— Congrats to Ariana Mirian who was named the campuswide student recipient of the UC San Diego Inclusive Excellence Award. The award recognizes those faculty, staff, students, departments and organizations who have made outstanding contributions in support of UC San Diego's commitment to inclusive excellence and diversity.

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. Brian Kantor

ACM CCS 2019 Test of Time Award November 13— A while back, CSE alumni Tom Ristenpart, Hovav Shacham and Stefan Savage (and co-author Eran Tromer) published one of the first cloud security papers called "Hey You Get Off Of My Cloud: Exploring Information Leakage in Third Party Clouds". Ten years and a couple thousand citations later, the paper has been named this year's winner of the ACM CCS Test of Time Award. The award recognizes papers from CCS ten years prior that have had the greatest impact on security research and practice over the past decade. Congrats to Tom, Hovav and Stefan! (and a particular congrats to Hovav who has now won TWO of these awards!)
