Holding a Ph.D. in Optical Sciences, this optics and optical data storage expert witness has more than 30 years of experience in micro-optics, optical engineering, and photonics technologies. His work spans theoretical research, experimental investigation, and engineering development related to optical systems and imaging technologies. In an expert capacity, he has more than 20 years of experience providing consultation, deposition testimony, and courtroom testimony in matters involving optical technologies, photonics systems, and optical data storage platforms.

His professional work includes research and engineering related to micro-optics, laser-based systems, and optical data storage technologies such as compact discs, DVDs, and Blu-ray systems. His expertise also includes optical interference and coherence phenomena, diffraction theory, optical transfer functions, and beam-shaping techniques used in optical system performance evaluation. In addition, his work involves high-resolution optical imaging and nanoscale optical techniques, including near-field scanning optical microscopy (NSOM), the development of specialized near-field probes, and the use of solid immersion lenses to enhance imaging resolution beyond conventional diffraction limits. These technologies have applications in microscopy, lithography, and advanced optical data storage systems.
