With more than 30 years of experience, he is a Ph.D.-trained expert in audio forensics and acoustical engineering who analyzes recorded evidence in complex litigation. His work spans audio and video authentication, digital signal processing, psychoacoustics, and speech intelligibility, with a focus on detecting alterations such as editing or splicing and evaluating recorded events. He conducts voice comparison and “ear witness” analyses, along with acoustic evaluations involving gunshots, warning signals, and environmental sound conditions using standardized measurement and simulation methods.

Building on extensive casework, he applies his expertise to intellectual property disputes, including forensic musicology and copyright infringement involving comparative analysis of musical works, recordings, and production elements. His experience also includes evaluation of broadcast audio, remastered recordings, and voice-over identification, as well as targeted recovery and analysis of audio and video data from digital devices such as cell phones and recording systems. He has also addressed patent and technology-related matters involving audio and audiovisual systems.

Across his career, he has contributed to over 1,000 forensic cases and has provided testimony in more than 100 depositions and court proceedings across federal, state, and international venues. His background includes applied research in acoustics, human perception of sound, and communication systems, supporting reliable interpretation of complex audio evidence in legal contexts. He has also served in leadership and advisory roles within professional organizations and standards committees related to audio engineering, forensic acoustics, and psychoacoustics, while contributing to peer-reviewed research, technical standards, and interdisciplinary collaborations involving acoustics, auditory perception, and forensic media analysis.
