Expert has a Ph.D. and has over 30 years of experience in the areas of lasers, nonlinear optics, nonlinear spectroscopy, and EUV lithography (formerly Soft X-ray Projection Lithography). His professional career achievements include being a Distinguished Member of the Technical Staff for AT&T Bell Laboratories, and Principal Scientist for Components Research at Intel Corporation. He has made numerous contributions to the field of optics and photonics in the following areas of research and development: nonlinear optics; single-mode, Q-switched ruby lasers; optical parametric oscillators; distributed-feedback lasers; self-trapping of light; doppler-free, two-photon spectroscopy; nonlinear optical spectroscopy; laser processing of materials; resonance-radiation pressure on atoms; optical cooling of atoms (first demonstration of "Optical Molasses"); optical trapping of atoms (first demonstration). Expert has been an author of over 110 scientific publications and has been issued 15 patents. He has previous experience as an expert witness. Most of the work he carried out at Intel in the field of photolithography was not published externally.
