Catalin Grigoras, Ph.D.
Director and Associate Professor
As Director of the National Center for Media Forensics, Grigoras has the
privilege to coordinate the Center’s activity, including education and
scientific projects. His research encompasses digital signal processing in
forensic multimedia, including digital recording authentication, audio/image
analysis, enhancement, and automatic speaker recognition. His research into
digital signal processing has resulted in advanced methods to authenticate
digital audio/video recordings and semiautomatic systems for forensic speaker
Grigoras was chairman of the European Network of Forensic Science
Institutes - Forensic Speech and Audio Analysis Working Group between 2007-2009.
He is a member of the Audio Engineering Society Subcommittee on Forensic Audio
and the International Association of Forensic Phonetics and Acoustics. He has
published numerous forensic audio/video articles and is a co-author of Best
Practice Guidelines for ENF Analysis in Forensic Authentication of Digital
Evidence (2009). Funding sponsors include Defense Advanced Research Projects Agency (DARPA) and the Department of Justice (DOJ).
Jeff M. Smith, M.S.
As Associate Director of the National Center for Media Forensics, Smith has the pleasure of helping build the foundation for strengthening forensic sciences in the U.S. through the Center’s education and research programs. Smith’s research areas include the forensic authentication of recorded media, forensic speaker recognition, and the evolving synergy that exists amongst the Digital and Multimedia Evidence disciplines. He is a member of the Audio Engineering Society (AES) as Chair of the Technical Committee on Audio Forensics and past chair of the Colorado Section of the AES. He is also a Fellow of the American Academy of Forensic Sciences (AAFS). He works closely with law enforcement as member-at-large of the Scientific Working Group on Digital Evidence (SWGDE) Executive Committee and as a member of its Audio Committee. Smith is an alumnus of CU Denver. Funding sponsors include Defense Advanced Research Projects Agency (DARPA) and the Department of Justice (DOJ).
Cole Whitecotton, M.S.
As the IT Professional for the National Center for Media Forensics, Whitecotton develops and maintains the equipment and software used throughout the Center’s education and research programs, both online and in the classroom and labs. As an alumnus of the Master of Science in Recording Arts emphasis in Media Forensics (MSRA-MF) program, he is also excited to contribute back via teaching and leveraging new technologies to expand and strengthen students' experiences as they forge their own paths in the digital and multimedia forensic disciplines. Whitecotton’s research areas include recompression effects on video, especially YouTube compression effects, and specialization in hardware and computer configurations. Whitecotton is a member of the Audio Engineering Society (AES) and the American Academy of Forensic Sciences (AAFS).
