Todd Combs, Ph.D. Associate Laboratory Director, Energy and Environment Science and Technology Research Areas:
Biography:
Dr. Combs recently joined INL as the Associate Laboratory Director for EES&T. Before joining INL, he served as the Director of the Global Science Division at Argonne National Laboratory where he led a multidisciplinary research team of over 200 that found solutions to protect against, mitigate, respond to, and recover from a wide spectrum of national and global security threats. He also served nearly 14 months as Argonne's interim Associate Laboratory Director for Energy and Global Security, where he led an applied R&D organization of over 800 people addressing domestic and global sustainable energy and security issues. In his role, he oversaw research and operational activities of the energy systems, nuclear engineering, and global security sciences division.
Todd earned his doctorate in operations research and master's degree in operations analysis from the Air Force Institute of Technology, and is a graduate of the U.S. Military Academy at West Point. A colonel in the U.S. Air Force Reserve, his military experience includes assignments at the Air Force Research Laboratory, the Air Force Office of Scientific Research, and the Air Force Studies and Analyses Agency. He is a member of the Institute for Operations Research and the Management Sciences and the Military Operations Research Society.
