Professor of analytical chemistry and head of mass spectrometry group at the Department of Analytical Chemistry, University of Pardubice. His research started with the structural analysis of organic and organometallic compounds using mass spectrometry (MS) and its coupling with liquid chromatography, focused mainly on the metabolism of pharmaceutical and natural compounds. His present specialization is the lipidomic analysis of biological samples using liquid chromatography and supercritical fluid chromatography coupled to MS, shotgun MS, MALDI-MS and MS imaging. He has coauthored over 110 papers in peer-reviewed journals with h-index of 33 and given over 300 conference presentations including over 20 plenary and keynote lectures. He is a member of editorial board of Analytical and Bioanalytical Chemistry; Lipids; a guest editor of special volumes on Mass spectrometry in Journal of Chromatography A (2010, 2012 and 2016), Lipidomics in Analytical Chemistry (2014) and Analytical and Bioanalytical Chemistry (2015), editor of the book Extreme Chromatography: Faster, Hotter, Smaller (American Oil Chemical Society, 2011), and on Power List of 100 most influential people in the analytical sciences (The Analytical Scientist, 2013 and 2015).
