| Dr. Raynie is a Research Associate Professor in the Department of Chemistry and Biochemistry at South Dakota State University. Prior to joining SDSU, he was employed for eleven years as a Senior Scientist at Procter and Gamble's Corporate Research Division. Dr. Raynie’s broad research interests are in the field of sustainability and green chemistry. His two major areas of research are bioprocessing using supercritical fluids and related technologies and analytical separations. Active projects in this area include pretreatment strategies for lignocellulosic biomass (including use of supercritical fluids, ionic liquids, and deep eutectic solvents) and the use of liquid carbon dioxide in the leather tanning industry. Analytical separations research includes high-resolution chromatography (high-temperature LC and SFC), chromatographic sample preparation (ASE, SFE, SPME, and SPE), chromatography theory, green analytical chemistry, and problem-based learning in analytical chemistry. This analytical research is applied to measurements of the environmental fate and transport of anthropogenic compounds like antimicrobials and fluorinated surfactants. In addition to several publications and presentations in these areas, he has taught short courses covering ASE, SFE, SPME, sample preparation, green chemistry, and analytical problem-solving, and served on the editorial advisory boards of the Journal of Microcolumn Separations, the Encyclopedia of Separation Science, and Pharmaceutical Formulation and Quality. |
