Georges Guiochon graduated from Ecole Polytechnique (Paris, France) and received a Ph.D. in chemistry from the University of Paris (France). He was a Professor of chemistry at Ecole Polytechnique and at the University Pierre et Marie Curie of Paris until 1984, then at Georgetown University, Washington, D.C. (1984-1987). He is a Professor of Chemistry at the University of Tennessee since 1987. His research interests include all analytical and preparative aspects of gas, liquid, and supercritical fluid chromatography, theory, instrumentation and applications, and the problems of physical chemistry related to chromatography, including solution and adsorption thermodynamics, mass and energy transfers in chromatography, detector principles, and the consolidation of beds of fine particles. His current work is in the theory of nonlinear chromatography in supercritical fluid chromatography and in modern column technology.
