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.

Recent News

Alex C. Snoeren December 17— The year ends on a high note with the fantastic news that Alex Snoeren has been named an ACM Fellow for his "his innovative approaches to measuring, managing and directing network traffic". He will henceforth be known as Packet Whisperer.

December 1— The fall hike was a six-mile hike in Torrey Pines. The park closed the trails, so we hiked the road to the golf course and then back down along the beach.   (Pics)   (GPS Track)   (All Hikes) Torrey Pines

Lixiang Ao November 9— In the news! GCN highlights Lixiang Ao's and Liz Izhikevich's paper at ACM SOCC on the Sprocket serverless video processing system: "Sprocket kicks video processing into high gear".

November 7— Alumna Renata Teixeira has been named an ACM Distinguished Member. Congratulations, Renata! Renata Teixeira

Alan Turing Memorial Scholarship November 1The recipients of this year's Alan Turing Memorial Scholarship are Anton Sydorenko (senior, Computer Science) and Adrian Mendoza (junior, Computer Engineering). These scholarships mark the third consecutive year that the Center for Networked Systems has recognized students studying networked systems for their academic commitment and involvement in the LGBT community, and the first year that it has awarded the scholarship to more than one student. Congratulations Anton and Adrian!

August 21— In exciting news, Amogh Dhamdhere, Alex Gamero-Garrido, Gautam Akiwate, Alex Snoeren and their co-authors received the Best Paper award at SIGCOMM 2018 today in Budapest for their paper on inferring interdomain congestion. Congratulations to all! (Curiously, Alex was the first person to register for the conference...did he know?!?) SIGCOMM 2018 Best Paper

OSDI 2018 Best Paper October 8— Alumna Ranjita Bhagwan and her co-authors at Microsoft Research India won a Jay Lepreau Best Paper Award for their OSDI 2018 paper, "Orca: Differential Bug Localization in Large-Scale Services". Congratulations, Ranjita!

July 27— Congratulations to Joe DeBlasio, who successfully defended his dissertation today on "Countering Financially-Motivated Malicious Actors on the Internet"! At the end of summer Joe will join the ever-growing UCSD contingent at Google. Joe DeBlasio
