Dr. Todd J. Toops has been at Oak Ridge National Laboratory (ORNL) since 2001 where he is a Distinguished R&D Scientist in the Applied Catalysis and Emissions Research Group. He also has an appointment as Adjunct Faculty at the University of Tennessee. After receiving his B.S. in Chemical Engineering in 1996 from the University of New Mexico, Dr. Toops pursued his Ph.D. in Chemical Engineering from the Pennsylvania State University under Prof. Albert Vannice where he studied catalysis and emissions control with an emphasis on improving fundamental understanding of systems under realistic conditions. His research at ORNL has covered a wide range of clean energy topics including emissions control, biofuels, fuel cells, electrolysis, and neutron imaging of transportation devices. He has published over 135 journal articles and book chapters, 65 DOE reports, 4 patents/patent applications, and delivered over 80 invited/keynote/plenary lectures. He is a two-time winner of the Biodiesel Researcher of the Year (2012 and 2015) award and has an R&D 100 award (2014). He is a member of the Society of Automotive Engineers, North American Catalysis Society, American Institute of Chemical Engineers, and American Chemical Society. He is the Chair of the 29th North American Catalysis Society Meeting (NAM29) to be held in 2025 in Atlanta, served as the Chair of the 8th International Conference on Environmental Catalysis (2014), and is on the Editorial Board of the scientific journal: Emissions Control Science and Technology. Additionally, he has either mentored or advised 20+ post-graduate fellows/graduate students.
