Doctoral Dissertation — Analysis of the Daubert trilogy (FRE 702) and admissibility of psycholegal evidence
Dr. Cohen is a New Jersey licensed clinical psychologist specializing in forensic psychology who has conducted over a thousand forensic assessments across criminal, civil, family, and administrative matters.
He has been retained and called by defense counsel, prosecutors, and plaintiff's attorneys. He has served as a court-appointed expert pursuant to California Evidence Code 730 and has conducted fitness-for-duty and pre-employment psychological screenings for law enforcement agencies across New Jersey.
His experience spans both state and federal systems, and his doctoral dissertation involved a direct analysis of the Daubert trilogy as it pertains to psycholegal evidence and expert testimony — the same standard his work is built to satisfy.
Dr. Cohen holds advanced training in nonverbal behavior analysis and was trained as a hostage negotiator by a federal law enforcement agency. He is a member of the American Psychological Association and the American Psychology-Law Society (APA Division 41).
Although his practice is built on education, training, and experience, his most prized asset is his work ethic. His dedication to producing timely, comprehensive, objective, and defensible assessments is driven by an intrinsic passion for the work.
