CAST Meeting

Professor Highlight

Dr. David E. Hobart

David E. Hobart received his BA from Rollins College, Winter Park, Florida in 1971. After serving four years in the U.S. Air Force as an electronics technician on the SR-71 “Blackbird” spy plane, he attended the University of Tennessee, Knoxville and earned his Ph.D. in chemistry in 1981. He then served as a postdoc at the Transuranium Research Laboratory, Oak Ridge National Laboratory, Tennessee. In 1983 he accepted a staff member position at Los Alamos National Laboratory (LANL), New Mexico. During his LANL tenure, he served as P.I. for "Actinides in Near-Neutral Solutions" and the "Yucca Mountain Solubility and Speciation Task."  While at LANL, he served as a technical consultant for Sandia National Laboratories as a member of the Expert Panel for Radionuclide Solubility for the Waste Isolation Pilot Plant (WIPP) nuclear waste repository. He was also selected for a change-of-station assignment to DOE Headquarters, Washington, D.C., as technical consultant for the Hanford Nuclear Waste Tanks. In 1993 he assumed the position of Group Leader of the Actinide Geochemistry Group, Earth Sciences Division, Lawrence Berkeley National Laboratory, California. During that time, he was the P.I. for “Radionuclide Behavior in the Environment”.  After working as a contractor for DOE Carlsbad Nuclear Waste Isolation Pilot Plant (WIPP) operations for 5 years, he rejoined LANL in 1999 as a maintenance Team Leader in the Actinide Analytical Chemistry Group. He served as Program Manager for Pit Manufacturing at LANL. He was also an adjunct professor of chemistry at the University of New Mexico, Los Alamos, and California State University, Hayward. 


David is listed in “American Men and Women in Science”, “Who's Who in the West”, “Who's Who in Science and Technology” and “International Leaders in Achievement”. He is a Fellow of the American Chemical Society, recipient of the "Rollins College Alumni Achievement Award," and served as Chair of the Actinides 1993 International Conference. He is serving as International Advisory Committee member for the “Plutonium Futures – The Science Conference” series. He is Past Chair of the ACS Nuclear Chemistry and Technology Division.


In 2012 Hobart retired from Los Alamos Laboratory and moved to Santa Rosa Beach, Florida where his wife later informed him that they were spending too much quality time together and that he should go find something to do! He then accepted a position as Research Professor III in the Department of Chemistry and Biochemistry at Florida State University, Tallahassee where he also serves as the Chief Operations Officer for CAST. At FSU he is lecturing, mentoring graduate students and performing f-element research. Author of over seventy journal articles and five book chapters, he is presently delivering lectures and organizing symposia at international conferences and national ACS meetings, is a guest scientist at LANL and member of the International Advisory Committee and chapter co-author for the rewrite of the classic reference, “The Plutonium Handbook.” His research interests include lanthanide and actinide element solution and solid-state chemistries; speciation, solubility, spectroscopy, redox behavior, thermodynamics, complexation, etc.
