Michael J. Freedman is a Full Professor of Computer Science at Princeton University. His research broadly focuses on distributed systems, networking, and security.

He developed and operated several self-managing systems, including CoralCDN (a decentralized content distribution network that has served millions of users daily since 2004) and DONAR (a server resolution system that powered the FCC’s Consumer Broadband Test). Other research has included software-defined and service-centric networking, cloud storage and data management, data analytics, untrusted cloud services, fault-tolerant distributed systems, virtual world systems, peer-to-peer systems, and various privacy-enhancing and anti-censorship systems.

Professor 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. He is currently the co-founder/CEO of Iobeam, which is building a data analysis platform for connected devices.

Professor Freedman’s honors include a Presidential Early Career Award for Scientists and Engineers (PECASE, nominated by the NSF and given by President Obama), an Alfred P. Sloan Fellowship, a NSF CAREER Award, an Office of Naval Research Young Investigator Award, a DARPA Computer Science Study Group membership, teaching awards from Princeton University, and multiple award publications.

Freedman has submitted numerous expert reports on both the (in)validity and (non)infringement sides of patent litigation, and has written IPR and CBM declarations. He has been deposed, and has testified on behalf of clients in court.
