Harald Gröger received his Diploma in Chemistry from Friedrich-Alexander University Erlangen-Nuremberg and Carl von Ossietzky University of Oldenburg in 1994. After receiving his doctoral degree from the same university in 1997, he stayed as a postdoctoral fellow at the University of Tokyo from 1997 to 1998. In 1998, he joined the research department at the Chemische Forschung of SKW Trostberg AG. After the merger of Degussa-Hüls AG with Degussa AG in 2001, he became Project Manager in the Project House Biotechnology of Degussa AG. From 2004 to 2006, he worked as a Senior Project Manager at the research unit Service Center Biocatalysis of Degussa AG. From 2006 to 2011, he was W2-Professor (Associate Professor) of Organic Chemistry at the University of Erlangen-Nürnberg, and since April 2011, he has been W3-Professor (Full Professor) of Organic Chemistry at Bielefeld University. His research topics mainly include the biocatalytic synthesis of organic compounds (e.g., pharmaceuticals, specialty chemicals), technical biocatalytic processes, the combination of chemo- and biocatalysis towards one-pot processes in water, and the conversion of biorenewable feedstocks, with a distinctive interdisciplinary approach combining biological, organic synthetic, and process engineering methodologies.
