Rex Geveden is the Chief Operating Officer of BWX Technologies. Formerly, he was Executive Vice President of Teledyne Technologies Inc and President of Teledyne Dalsa in Waterloo, Ontario. Previously he was the president of Teledyne Brown Engineering and the Associate Administrator of NASA before that. He was selected for that position by NASA chief Michael Griffin on August 17, 2005, after having served in an acting capacity since June of that year. Griffin created the position immediately prior to assigning Geveden to fill it. The Associate Administrator's task is described as "oversight for all the agency's technical missions' areas and field center operations". Griffin also suggested Geveden was his right-hand man, saying "...if you get a decision from Rex, it's the agency's decision."
