An MIT-trained systems engineer with a hybrid technical-and-business background, he is a turnaround specialist who has led high-technology businesses from start-up scale to north of $200M in revenue, largely inside private-equity portfolios. At AvCarb he is steering a company with 1960s roots toward the center of the clean-energy transition.
