Recent News

November 14— Congratulations to Miro Haller for being awarded a 2024 Google PhD Fellowship! The Google PhD Fellowship Program recognizes outstanding graduate students doing exceptional work in computer science. Way to go Miro!

November 4— CSE alumni Sarah Meiklejohn, Marjori Pomarole, Grant Jordan, Kirilll Levchenko and Damon McCoy, along with Geoff Voelker and Stefan Savage received the ACM IMC Test of Time award today for their 2013 paper A Fistful of Bitcoins: Characterizing Payments Among Men with No Names which is credited with helping to establish the technique of cryptocurrency tracing (the core part of this story is told in Andy Greenberg's book, "Tracers in the Dark", as well as a summary article he wrote in Wired this year). Congrats to Sarah and all her collaborators!

November 1— On the tail of winning last year's "Outstanding Faculty Mentor" award, this year Geoff Voelker has received the "Outstanding Graduate Student Mentor" award. To quote from a student, "With Geoff, no meeting is ever rushed and his whole undivided attention is given to each and every student". We continue to be unsurprised, yet proud! Congrats Goff!

October 9— Congratulations to Keegan Ryan, George Sullivan, Nadia Heninger, and Kaiwen He for winning the 2024 CSAW Applied Research Award for "Most Notable Paper: Technical Impact" for their CCS 2023 paper, Passive SSH Key Compromise via Lattices.

October 22— Each year, the Center for Networked Systems (CNS) awards the Alan Turing Memorial Scholarship and the Alan Turing Memorial Teradata 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 Jonathan Ty for his academic achievements and his community engagement and leadership efforts. Congrats Jonathan!

October 3— Yiying Zhang became one of the first-ever Google Academic Research Award (GARA) winners for her project, "Learned Tiered Memory System: Optimizing Tiered Memory Performance with ML-Based Memory Access Pattern Prediction". Congratulations Yiying!

September 9— We just learned that Katherine Izhikevich has been named to this year's class of UCSD ACRS Scholars. Congrats Katherine!

July 22— Congratulations to Rajdeep Das for defending his dissertation, "Multiprocessing and Runtime Programmability on Virtualized RMT Switches". After a well-deserved vacation, Rajdeep will be starting at Microsoft Azure where he will be working on advanced networking devices. Congrats Rajdeep!

July 18— Today Yibo Guo defended his dissertation, "Towards Leaner Data Centers: Energy Efficiency and Carbon Savings through Network Optimization". Yibo is going to be joining Google where he'll contribute to solving their systems and networking challenges. We're proud of you Yibo!

July 15— Today Anil Yelam defended his dissertation, "Flexible, Application-Guided Paging for Far Memory". After a brief, well-deserved break, Anil will be (re-)joining Google full time to improve the efficiency of their AI Hypercomputer--or something like that. Great job, Anil!

July 10— Congratulations to Hadi Givehchian, Nishant Bhaskar, Alexander Redding, Han Zhao, Aaron Schulman, and Dinesh Bharadia for their 2024 IEEE Security & Privacy paper on obfuscating BLE fingerprints. The paper describes a practical approach for preventing attackers from tracking mobile users, effectively fixing a vulnerability they identified in previous work.

June 27— Congrats to Amy Ousterhout and Sysnet affiliate Earlence Fernandes for winning Google Research Scholar awards!

June 7— Sysnet represents for the second year in a row! Congrats to Alex Bellon and Alisha Ukani for sweeping the "Service and Leadership" category of the CSE Doctoral awards and Katherine Izhikevich for winning the Research category for CSE Masters awards (Katherine is joining us a Ph.D. student starting this fall so she's set a high bar to start). Congrats everyone!

May 23— Congratulations to Stewart Grant for defending his dissertation, "Disaggregated Data Structures: Sharing and contention with RDMA and Programmable Networks". Stew is moving on to Roblox, where he will apply his talents to scaling their virutal environment. Congrats Stew!
