Dr. Jean-Marie (John) Dimandja received his B.A. in mathematics from Miami University (Oxford, Ohio) in 1989, and his M.S. and Ph.D. in Analytical Chemistry from Southern Illinois University (Carbondale, Illinois) in 1992 and 1997 respectively. His graduate work was performed under the tutelage of Professor John B. Phillips, the inventor of comprehensive two-dimensional gas chromatography (GCxGC). Dr. Dimandja was a research scientist at the Centers for Disease Control and Prevention (CDC) from 1997 to 2002, where he developed new biomonitoring methods for environmental toxicant analysis by GCxGC/TOF MS and GCxGC-ECD. He joined the faculty at Spelman College (Atlanta, Georgia) in 2002, where he is currently an assistant professor in the Chemistry Department. He maintains a strong research group – funded by federal grants from NSF and NIH and corporate support from several companies – that is focused on instrument and method development in GCxGC. Dr. Dimandja has authored over 120 publications/presentations, and he has organized and/or chaired several conference symposia on GCxGC at PITTCON, ACS, ISCC and the International Symposium on Multidimensional Gas Chromatography.
