Dr. Gregory R. Choppin joined the faculty at Florida State University in 1956 and from 1968 to
1976 he served as Chairman of the Department of Chemistry. He is a Robert O. Lawton Distinguished
Professor of Chemistry at Florida State University.
Dr. Choppin serves as a consultant to Lawrence Livermore National Laboratory, Argonne National
Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, as well as
several private laboratories. He has received two honorary degrees, D.Sc. (Loyola University)
and DTC (Chalmers University, Sweden). His major research interests are inorganic and
nuclear chemistry with emphasis on the lanthanide and actinide elements. Potentiometry, calorimetry,
NMR, and optical spectroscopy are among the methods used in his laboratory to study the thermodynamics
and kinetics of complexation and redox behavior of these elements. A major focus of his laboratory is
on the separation science of actinides and the environmental speciation of actinides by inorganic and organic ligands.
