Joe is CEO and a co-founder of RadianGEN.

Post academics, he has over 20 years of professional experience in the solar industry. Joe has held senior management positions at three successful U.S. solar power producers: Renewable Ventures (co-founder), MMA Renewable Ventures, and Fotowatio Renewable Ventures, where he led technical development, construction, and operations.
