Combining  Soft X-ray Microscopy with Electrochemistry to Study Redox-Sensitive Organic Materials



Martin Obst, Heisenberg-Professor for Experimental Biogeochemistry, started his study at the University of Bayreuth, Germany, He did his diploma in the interdisciplinary field of Geoecology in 1996 before he focused on geomicrobiology during his PhD at the Eawag/ETH Zurich. Soon he became interested in using synchrotron-based soft X-ray spectromicroscopy as a tool to study environmental processes at the sub micron scale. As a postdoc in Adam Hitchcock’s group at the Canadian Light Source (CLS) in Saskatoon, Canada, he was involved in the commissioning of the Scanning Transmission X-Ray Microscopy beamline and developed his own research program in environmental sciences before he returned to Germany. As a Emmy-Noether junior research group leader at the University of Tuebingen his research focused on the influence of environmental biofilms on the fate of heavy metals. In 2017 he became a Heisenberg-Professor for Experimental Biogeochemistry at the University of Bayreuth. His current research focusses on redox-transformations of carbon, iron or sulfur-species in the environment. Such processes are essential for various environmental topics including climate change, plant nutrition and environmental contaminations. Currently he is involved in the development of a combination of in-situ electrochemical manipulation/characterization of samples such as microbial organic polymers with (soft) X-ray absorption spectromicroscopy in the STXM.
