Joseph Greenfield, Ph.D.

Dr. Greenfield is also an Associate Professor of Information Technology Practice at the Viterbi School of Engineering at the University of Southern California (USC). In 2009, he authored the first undergraduate cyber security program at USC which attracted more than fifty students in its first year. In 2012, he launched a minor in Computer & Digital Forensics, adding domain specific forensic courses to the undergraduate catalogue in Enterprise and Network Forensics, eDiscovery, Mobile Device Security and Forensics, and Mac, OSX & iOS Forensics. In 2014, the Ponemon Institute ranked USC as 6th in the nation for “Best Schools for Cybersecurity” and the highest ranked on the West Coast. In 2019, he co-created an interdisciplinary bachelor’s degree in Intelligence and Cyber Operations, now a part of the USC Political Science and International Relations Department in the Dornsife College of Letters, Arts and Sciences.

Dr. Greenfield also engages in practical research in digital forensics. In 2009, he presented some of his research of peer-to-peer networks, specifically BitTorrent, to the Los Angeles Electronic Crimes Task Force (LAECTF) and the Los Angeles Chapter of the Information Systems Security Association (ISSA). He pioneered new techniques for associating downloaded content to the metadata files (.torrent files) with extreme accuracy. In 2012 and 2013, he presented a series of lectures to the LAECTF on Solid State Drives (SSDs), articulating the problems of flash memory for forensics and outlining how operating systems change their behavior when deployed on SSDs.

Dr. Greenfield holds a Bachelor’s Degree in Computer Engineering & Computer Science and a Master’s Degree in Computer Science from the University of Southern California. He completed his Ph. D. in Computer Science at the University of Rhode Island, where his research focused on parallel processing of all live files during the forensic bitstream image creation (https://digitalcommons.uri.edu/oa_diss/1082/).
