Gregory Kulacki

China project manager and senior analyst

Gregory has lived and worked in China for the better part of the last twenty-five years facilitating exchanges between academic, governmental, and professional organizations in both countries. Since joining the Union of Concerned Scientists in 2002, he has focused on promoting and conducting dialog between Chinese and American experts on nuclear arms control and space security. His areas of expertise are Chinese foreign and security policy, Chinese space program, international arms control, cross-cultural communication. He received his Ph.D. in Political Theory from the University of Maryland, College Park in 1994. Gregory also blogs on the Equation.

Dave Lochbaum

Director, Nuclear Safety Project

Mr. Lochbaum received a BS in Nuclear Engineering from the University of Tennessee in 1979 and worked as a nuclear engineer in nuclear power plants for 17 years. In 1992, he and a colleague identified a safety problem in a plant where they were working. When their concerns were ignored by the plant manager, the utility, and the Nuclear Regulatory Commission (NRC), they took the issue to Congress. The problem was eventually corrected at the original plant and at plants across the country. Lochbaum joined UCS in 1996 to work on nuclear power safety. He spent a year in 2009-10 working at the NRC Training Center in Tennessee. Areas of expertise: Nuclear power safety, nuclear technology and plant design, regulatory oversight, plant license renewal and decommissioning

Ed Lyman

Senior scientist

Dr. Lyman received his PhD in physics from Cornell University in 1992. He was a postdoctoral research scientist at Princeton University's Center for Energy and Environmental Studies, and then served as Scientific Director and President of the Nuclear Control Institute. He joined UCS in 2003. He is an active member of the Institute of Nuclear Materials Management and has served on expert panels of the Nuclear Regulatory Commission. His research focuses on security issues associated with the management of nuclear materials and the operation of nuclear power plants, particularly with respect to reprocessing and civil plutonium. Areas of expertise: Nuclear terrorism, proliferation risks of nuclear power, nuclear weapons policy
