After graduating from the University of Kentucky with a B.S. in Chemistry, I joined the Analytical Laboratory of a catalyst manufacturer in Louisville and was responsible for several instrumental analyses, including gas chromatographic methods.  I moved to Florida to work in the Quality Control Laboratory at the New Wales plant of International Minerals & Chemicals, Inc. (later IMC Phosphates), where I remained for twenty-eight years as chemist, supervisor, and senior chemist.  In 2002, I was promoted to Supervisor of the Environmental Laboratory located at IMC’s Four Corners mine.


During my years in the phosphate industry at IMC, I have gained experience in the analysis of phosphate rock and its derivatives by manual and automated wet chemical and instrument methods, including auto-titrators, ion chromatography, atomic absorption spectroscopy, inductively-coupled plasma optical emission spectroscopy, and inductively-coupled plasma mass spectrometry.


As a member of the Methods Committee of the Association of Fertilizer Phosphate Chemists (formerly the Association of Florida Phosphate Chemists), two editions of the AFPC methods manual were published, including a CD version.  Since 1991, I have been the Study Director (formerly Associate Referee) for Trace Elements in Fertilizers for the Association of Official Analytical Chemists (AOAC).


Publications have included “Free Water in Phosphogypsum” and “Investigation into the Validity of Using ICP-MS With Microwave Dissolution for the Analysis of Phosphatic Fertilizers and Animal Feedstuffs”, and I was a contributing author to Environmental Impact of Fertilizer on Soil and Water.
