Deputy Director for Operations and Chief Operating Officer

Craig R. Ferguson joined PPPL in 2019 as deputy director for operations and chief operating officer. He has more than 25 years of experience in managing aspects of U.S. Department of Energy (DOE) facilities including at SLAC and Jefferson Lab.
