Greg W. Charache, Ph.D., is currently the vice president of photonics at Metrohm Spectro Inc. (dba Innovative Photonic Solutions Inc.) in Plainsboro, New Jersey where he leads the development of next generation OEM, handheld, and laboratory spectroscopy components and systems. After receiving a Bachelor of Science degree from University of Delaware, Charache did graduate work at Rensselaer Polytechnic Institute (RPI) receiving a Master of Science degree and doctorate in electrical engineering in 1991 and 1994, respectively. He then joined Lockheed Martin’s Knolls Atomic Laboratory, Schenectady as a senior researcher from 1994-2000 working on InP- and GaSb-based thermo-photovoltaic devices and systems.

In 2000, he joined Princeton Lightwave Inc. as a senior researcher and reliability manager for high-power single-mode ridge waveguide InP-based semiconductor laser diodes used in the telecom industry. In 2002, the company was acquired by the TRUMPF Group for the development and manufacturing of high-power GaAs-based laser diodes for industrial applications. At TRUMPF Photonics Inc. from 2002 to 2018, he worked in various roles in both development and production including some of the first work on wavelength stabilization of laser diodes with volume Bragg gratings. Charache has published over 75 papers and has 10 patents.
