Adam Cohen, PhD

CTO, Co-founder


Adam B. Cohen, Ph.D., is leading the way to urban clean energy as the Chief Technology Officer and co-founder of NineDot Energy, building community energy sites to make the NYC metro grid cleaner, more resilient, more equitable and less costly. 

Projects in operation or under development that Adam has spearheaded include battery energy storage systems in Staten Island, the Bronx, Queens, Brooklyn, Long Island and Westchester County. 

Adam developed his exceptional understanding of how complex systems interact and evolve in his academic work (Ph.D. from the Chaos Group at University of Maryland and B.S. in physics from Bucknell University); he now applies his findings to the interconnected dynamics of energy markets, technologies, regulations and grid economics. Adam was a postdoctoral fellow at the U.S. Department of Energy (launching a research program applying social and behavioral science to scale up solar energy adoption) where Adam met his NineDot Energy co-founders. Adam is passionate about opportunities to modernize the urban electric system in a way that benefits all stakeholders. Recognizing the impact of Adam’s work, Crain’s New York Business selected Adam as an inaugural “2023 Notable Leader in Sustainability”.
