A dedicated member of the thermophotovoltaic (TPV) and heat transfer communities, Andrej's innovative research in TPVs has earned recognition from several prestigious organizations, including the National Science Foundation (CAREER Award), the University of Michigan (Henry Russel Award), and the Gordon and Betty Moore Foundation (Moore Inventor Finalist).

  • Greg Olsen

    Greg Olsen was the third private citizen to travel to the International Space Station (ISS). After an illustrious career as a research scientist and entrepreneur, Greg is now president of GHO Ventures in Princeton, NJ, an “angel” investments firm. Greg received his BS Physics (1966), BSEE and MS Physics (1968) from Fairleigh Dickinson University, then was awarded a Ph.D. in Materials Science from the University of Virginia (1971). Greg founded EPITAXX, a fiber-optic detector manufacturer in 1984 and it was sold in 1990 for $12 million. He then founded Sensors Unlimited, a near-infrared camera manufacturer in 1992 with Marshall Cohen. Sensors was sold to Finisar Corp. for $600 million in 2000, repurchased by the management team in 2002 for $6 million, and then sold again to Goodrich, Corp. in 2005 for $60 million.

  • John T. Preston

    John T. Preston is founder of TEM Capital and Science Advisor for Quadrant Management. Most of Mr. Preston’s career (30 years) was at the Massachusetts Institute of Technology, M.I.T., where he was the Director of Technology Development (and Licensing). In that capacity he was responsible for the commercialization of intellectual property developed at M.I.T. and oversaw activities that led to the creation of hundreds of new technology-based companies as well as the negotiation of thousands of licenses with existing companies.
