Denis E. Bergeron (Fed)

Denis E. Bergeron is a research chemist in the Radioactivity Group at the National Institute of Standards and Technology (NIST). He received a B.S. in Chemistry from Loyola University New Orleans and a Ph.D. in Physical Chemistry from the Pennsylvania State University. Following a postdoctoral fellowship at the University of Nottingham, Denis came to NIST as a National Research Council (NRC) Fellow in 2006 and joined the Radioactivity Group in 2008.

His current research spans basic radionuclide metrology, standards for nuclear medicine, and the chemistry of (reverse) micellar solutions. He is Editor-in-Chief of Applied Radiation and Isotopes, serves on several standards committees, and is part of collaborations exploring neutrino physics and developing next-generation techniques for measuring radioactive decay. He has more than 75 publications, with several in high-profile journals including Science, Nano Letters, and Physical Review Letters.
