Short Bio

Michael J. Freedman is a Professor in the Computer Science Department at Princeton University, as well as the cofounder/CEO of iobeam, a data analysis platform for the Internet of Things. His research broadly focuses on distributed systems, networking, and security.

Prior to joining Princeton in 2007, he received his Ph.D. in computer science from NYU's Courant Institute and his S.B. and M.Eng. degrees from MIT. He developed and operates several self-managing systems -- including CoralCDN, a decentralized content distribution network, and DONAR, a server resolution system that powered the FCC's Consumer Broadband Test -- which serve millions of users daily. Other research has included software-defined and service-centric networking, cloud storage and data management, untrusted cloud services, fault-tolerant distributed systems, virtual world systems, peer-to-peer systems, and various privacy-enhancing and anti-censorship systems. Freedman's work on IP geolocation and intelligence led him to co-found Illuminics Systems, which was acquired by Quova (now part of Neustar) in 2006. His work on programmable enterprise networking (Ethane) helped form the basis for the OpenFlow / software-defined networking (SDN) architecture.

Honors include a Presidential Early Career Award for Scientists and Engineers (PECASE), Sloan Fellowship, NSF CAREER Award, Office of Naval Research Young Investigator Award, DARPA Computer Science Study Group membership, and multiple award publications.
