The primary focus of Professor Pawliszyn's research program is the design of highly automated and integrated instrumentation for isolating analytes from complex matrices and the subsequent separation, identification, and determination of these species.  The primary separation tools used by his group are Gas Chromatography, Liquid Chromatography, and Capillary Electrophoresis coupled to a variety of detection systems, including a range of mass spectrometry techniques as well as ambient ionization techniques. Currently, his research is focusing on the elimination of organic solvents from the sample preparation step and miniaturization of the sampling devices to facilitate on-site monitoring and in-vivo analysis.  Several alternative techniques to solvent extraction are investigated including the use of coated fibers, packed needles, membranes, and supercritical fluids.  Dr. Pawliszyn is exploring the application of computational and modeling techniques to enhance sample preparation, chromatographic separations, and detection performance.  The major area of his interest involves the development and application of imaging detection techniques for microcolumn chromatography, capillary electrophoresis, and microchip separation devices.Professor Pawliszyn has supervised 65 PhD and 70 MS students, and he is an author of over 750 scientific publications and a book on Solid Phase Microextraction. His Hirsch Index (H-index) is 108.  He is a Fellow of the Royal Society of Canada, Editor-in-Chief of Trends in Analytical Chemistry and Green Analytical Chemistry.
