David Choffnes is an associate professor in the Khoury College of Computer Sciences at Northeastern University. Since joining Northeastern in 2013, he’s taught Fundamentals of Computer Networks and Networks and Distributed Systems. He’s also a founding member of Northeastern’s Cybersecurity and Privacy Institute; which aims to safeguard critical technology by forging partnerships with industry leaders and international academics. He earned his PhD in Computer Science from Northwestern University and his BA in Physics and French from Amherst College.

Choffnes’ approach combines science and engineering to understand and improve the performance, reliability, and security of internet systems. Using scientific analysis, he empirically measures computer systems to understand how well they match existing models and assumptions. Through investigating the root causes for violations of those models and assumptions, he often designs new models. As an engineer, he builds and evaluates systems to allow researchers, users, and policymakers to benefit from the result.

He has co-authored more than 60 peer-reviewed publications, his work has been cited more than 3,700 times, and his research is supported by funding sources such as the National Science Foundation, Department of Homeland Security, Google, Comcast, Verizon, Arcep, and the Data Transparency Lab. Choffnes‘ research has been covered by the popular press in print and on film, including ABC’s 20/20, CBS News, the Harvest documentary film, PBS, NPR, the Boston Globe, NBC News, WIRED, Vice News, and Science Magazine. His awards include an NSF Career Award, two Google Faculty Awards, two IRTF Applied Networking Research Prizes, a USENIX Security Distinguished Paper Award, an NDSS Distinguished Paper Award, the ACM/CRA Computing Innovation Fellowship, and the Outstanding Dissertation Award in EECS at Northwestern University.
