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.

Thanks Priyal for all of your hard work and devotion to everyone in the department! We wish you the best as you continue your journey in the Ph.D. program at the University of Washington.

June 2— The awards keep on rolling in! Today it was announced that Stefan Savage has received the 2021 Academic Senate Distinguished Research Award, which is awarded "for the ground-breaking research conducted by members of the UCSD faculty". This particular award comes with work, however: Stefan has to give a university-wide lecture on his research. Congratulations Stefan, and we all look forward to your lecture! Stefan Savage

AAAS April 22— Congratulations to Stefan Savage for being elected to the American Academy of Arts & Sciences! The Academy celebrates excellence across every field of human endeavor "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." Being elected to the Academy is a tremendous honor and outstanding achievement. Way to go, Stefan! Stefan Savage

Audrey Randall January 5— Congratulations to Audrey Randall (and her co-authors) for being named as a winner of the Internet Research Task Force's Applied Networking Research Prize for her work on the Trufflehunter DNS inference system.
