    Robert Head
    Director, RVC Photonics LLC

    Robert V. Chimenti is the Director of RVC Photonics LLC (Pitman, NJ), as well as a Visiting Assistant Professor in the Department of Physics and Astronomy at Rowan University (Glassboro, NJ). He has earned undergraduate degrees in physics, photonics, and business administration, as well as an M.S. in Electro-Optics from the University of Dayton. Over a nearly 20-year career in optics and photonics, he has primarily focused on the development of new laser and spectroscopy applications, with a heavy emphasis on vibrational spectroscopy. He is also very heavily involved in the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS), where he has served for several years as the Workshops Chair for the annual SciX conference and will be taking over as General Chair for the 2021 SciX conference.
