Dr. Petr Vozka is an Associate Professor of Analytical Chemistry at California State University, Los Angeles (CSULA), where he also directs the Complex Chemical Composition Analysis Laboratory (C3AL). His research lies at the forefront of multidimensional chromatography and mass spectrometry, with a primary focus on developing advanced analytical techniques, especially GC×GC-FID and GC×GC-TOFMS, for characterizing complex mixtures, including products from plastic waste conversion, fingerprints, and organic pollutants adsorbed on microplastics. He has over 30 peer-reviewed publications, a book chapter, one patent, and over 50 conference presentations, including 10 invited talks and a keynote address at the 14th Multidimensional Chromatography Workshop (MDCW 2023), where he now serves as co-chair. He also organizes the GC×GC symposium at ACS Fall Meetings (since 2023) and hosted the 15th MDCW on the CSULA campus in 2024.
