Michael Gelles


Dr. Michael Gelles believes that cyber security is really all about people. Companies and agencies need to develop a workforce that is culturally sensitive to cyber security threats. This includes vetting potential employees, providing clear controls on the flow of information, and sustained training to support the on-going mission.

Although most of his career was spent in federal agencies, Mike joined Deloitte in 2006 and is currently a director with Deloitte Consulting LLPd's Federal practice in Washington, D.C., consulting in the areas of human capital management and systems and operations.

"Deloitte creates a work environment that potentiates great ideas and transforms them into high value solutions for our clients that may mitigate the threat of the insider."


Mike was the chief psychologist for the Naval Criminal Investigative Service (NCIS) for more than 16 years. In that capacity, he assisted the NCIS and a multitude of other federal, state and local law enforcement agencies with criminal, counterintelligence and counterterrorism investigations and operations. He was the lead psychologist for the behavioral consultation team for the Criminal Investigations Task Force, and a member of numerous other task forces in the areas of workplace violence, insider threat and ethics in consultation to national security. Prior to joining the NCIS in 1990, he served as a clinical psychologist for the U.S. Navy.

Mike is active in a number of professional organizations, including the American Psychological Association Division of Police Psychology, the International Association of Chiefs of Police, the Society of Psychologists in Management.. He is also a frequent lecturer and has published numerous professional papers on topics related to organizational management in operational settings, forensic psychology, law enforcement, terrorism and counterintelligence.
