An Audio Systems Engineer and expert witness with more than 40 years of experience in audio and electronic systems design, this professional provides technical analysis in patent litigation involving digital audio technologies and motion picture sound systems. The expert has served as an expert witness in patent litigation and has been deposed in matters relating to the development of digital soundtrack technologies. The expert holds a Master of Scientific Instrumentation with an applied electrical engineering focus and a bachelor’s degree emphasizing musical technology, physics, audio, and acoustics. The expert has been a member of the Audio Engineering Society for over 45 years.

The expert’s engineering work ranges from discrete transistor circuit design to complex application-specific integrated circuits (ASICs) and digital systems development. As Project Engineer and lead within a film technology group, this expert led the team that developed a multichannel digital motion picture film sound format. Responsibilities included system architecture and oversight of 6 product classes, including a six-channel digital recorder and AC-3 formatter, film recorder systems, printhead adapters, and cinema decoder adapters.

Earlier work included development of hardware and software for an Edge Code Writer and Reader used to encode proprietary barcode information on motion picture film and recover it using optical sensing. These roles involved analog and digital circuit design, digital encoding and decoding systems, and motion picture film technology.

In subsequent leadership roles, including Director of Licensing Engineering within a consumer division, this expert built and managed a team that is responsible for specifying, testing, and reporting on digital technologies used in Laser Disc, DVD, and HDTV products. The expert later served as Senior Staff Engineer, contributing to professional and consumer audio product development and defining testing tools for digital audio systems.

The expert is the founder of an engineering enterprise that developed and patented a method and apparatus for visualizing and measuring soundfields within enclosed spaces using multiple acoustic sensors with visible light outputs. 5 United States patents have been awarded relating to motion picture sound recovery, encoded storage media, and sound sensor array technologies. Recognition includes a Scientific and Technical Academy Award for contributions to the development of a digital motion picture sound system.
