Ronald Collé (Feb. 11, 1946 - ) is an internationally-recognized specialist with over thirty years of experience in nuclear and radiochemistry, radionuclidic metrology, and the development of standards. He has been at the National Institute of Standards and Technology (NIST) since 1974 and currently serves as a Research Chemist in the Radioactivity Group of the NIST Physics Laboratory (Ionizing Radiation Division). Previously, he held research positions at Brookhaven National Laboratory, the State University of New York at Albany, and at the University of Maryland. He received a B.Sc. Chemistry from the Georgia Institute of Technology in 1969, a Ph.D. in Chemistry (Nuclear and Radiochemistry) from Rensselaer Polytechnic Institute in 1972, and a M.S. Adm. (Administration of Science and Technology) from George Washington University in 1979. He has published over ninty research papers, and is the originator (with Churchill Eisenhart) of the type A and type B uncertainty distinction approach as used for measurement uncertainty treatments. This approach is now adopted by most world-wide international scientific organizations. He spent two years on sabbatical in Paris (2003-2005) where he taught mathematics at the Victor Hugo Scool of EaB International and at the American University of Paris.
