Recent News

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!

May 23— 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!

February 1— Sysnet members have a long history with USENIX. Many of us remember when the only USENIX Conferences were "Winter" and "Summer", and several of us were there at the first OSDI and the first NSDI, as USENIX became a dominant academic publisher in our field. Thus, we could not be more proud that our own George Porter has been elected to the USENIX board. Keep the flame burning George!

January 31— Congrats to Stefan Savage, Taylor Berg-Kirkpatrick (and Geoff Voelker, the application form only allowed two names) and their students for receiving one of the first Google "Trust and Safety" Research Awards for their work focused on using Large Language Models in scam honeypots. And we hear they wrote the proposal without any help from AI!

January 17— Each year the Jacbos School offers awards for faculty demonstrating exceptional Teaching or Mentorship. We were not surprised to learn that Pat Pannuto received the Outstanding Graduate Mentor award (Aaron Schulman having won just last year!) nor that Geoff Voelker received the sole award for "Outstanding Faculty Mentor". We were not surprised, but we are proud! Contrats folks!
