Matt Orosz, Ph.D.
Founder and CEO
Dr. Orosz is a chief executive and renewable energy systems engineer with 15 years of leadership experience in engineering design, technology innovation, social entrepreneurship and energy project management as a co-founder of MIT spin-out STG International, as project manager at Cogenra Solar, and as CEO of OnePower. As company founder and project leader, he is responsible for corporate strategy, overseeing global business development, directing technical and financial divisions, and leveraging innovation and a world-class team to drive value in energy access. He holds a US patent in Solar Energy Conversion and has managed cross-cutting teams in academic research labs, energy start-ups and venture-backed solar companies with a direct responsibility for complex, multi-million-dollar high technology energy projects.
Dr. Orosz is an Echoing Green Fellow, Fulbright Scholar, and former Peace Corps volunteer, where he proudly served in Lesotho (2000-2002). Living in Phamong in the Mohale’s Hoek district without electricity for two years served as the motivation for his passion for designing and collaboratively implementing energy infrastructure solutions, and his career focus on global energy access is built on a foundation made in Lesotho. As Director of STG, he founded the most advanced rapid prototyping manufacturing facility in Lesotho with collaborators from the Lesotho government’s Appropriate Technology Services. In 2014, STG Lesotho, a locally registered association, became Africa’s first firm to export solar technology (designed and built in Lesotho) to customers in Europe.
He graduated from the Massachusetts Institute of Technology with a Ph.D. in Civil and Environmental Engineering, a S.M. in Technology and Policy, and an M. Eng. in Civil and Environmental Engineering. He holds a B.S. degree in Environmental Studies from Dartmouth College.
