Andrew R. Felmy, Ph.D.
Laboratory Fellow, WR Wiley Environmental Molecular Sciences Laboratory, Chief Scientist for Scientific ProgramsResearch Interests
- Thermodynamics of Aqueous Electrolytes
- Development of Geochemical Models
- Thermodynamics of Surface Complexation Reactions
- Utilization of molecular dynamics models for estimation of thermodynamic properties
Dr. Felmy also has a strong interest in the development of thermodynamic models for adsorption reactions at mineral surfaces, in particular, the use of molecular dynamics calculations to establish intrinsic binding constants for individual adsorption sites.
Past Experience
Dr. Felmy originally joined Battelle in March of 1980 as a Grade I Scientist. In 1982 he was promoted to Research Scientist and in 1983 went on educational leave to obtain his PhD in theoretical physical chemistry at the University of California, San Diego under Professor John H. Weare. Dr. Felmy received his PhD in 1988 and returned to Battelle. Since returning to Battelle, he has been promoted successively to Grade III Senior Research Scientist, Grade IV Staff Scientist, Technical Group Leader, Technical Group Manager of the Thermodynamic and Molecular Geochemistry Group, and is now the Acting Associate Director for Environmental Dynamics and Simulation in the EMSL.
Education
- B.S. 1977 Environmental Resource Management, Pennsylvania State University
- M.S. 1981 Environmental Engineering, University of Washington
- PhD 1988 Chemistry, University of California, San Diego

Other
Dr. Felmy has over 15 years of experience in the development and application of aqueous thermodynamic models and has a total of over 100 journal articles, project reports, symposium proceedings, or invited presentations in the area of aqueous thermodynamics. He was the original author of the MINTEQ geochemical model for EPA, a model still used nationally over twelve years after its initial release. Dr. Felmy has also developed several other geochemical models including GMIN a geochemical model based on free energy minimization, and FOWL-GH a user-oriented, coupled chemical/water balance model for predicting the chemical composition, volume and seasonal variability of leachates from electric utility by-product storage sites.
