Before joining Carnegie, for over 20 years he was an editor and correspondent for nuclear energy publications, including Nucleonics Week and Nuclear Fuel, published by the Platts division of the McGraw-Hill Companies. From the late 1980s until the mid-1990s, he covered nuclear developments in the Soviet bloc, including research on the USSR’s nuclear fuel cycle facilities and its nuclear materials inventories. Since the mid-1990s, his work has focused on emerging nuclear programs in Asia, including China and India. Since 2003, he has made many detailed findings about clandestine procurement in Europe related to gas centrifuge uranium enrichment programs in Iran, Libya, North Korea, and Pakistan. His Carnegie report, “The Future of the Nuclear Suppliers Group,” was published in December.
