Gerrit heads UFZ Department of Ecological Chemistry. He is Professor of Theoretical and Ecological Chemistry at the Technical University Bergakademie Freiberg, Honorary Professor of Chemical Ecotoxicology at the University of Leipzig, Lecturer of Toxicology at the University of Halle-Wittenberg, and chair of the Expert Panel “Chemical Safety” of the GDCh (German Chemical Society) and GT (German Society of Toxicology). His research into environmental and human health focuses on structure-activity relationships, employing computational chemistry, chemoassays, bioassays, and chemoinformatics to study compound toxicity, biotransformation, reactivity, partitioning and degradation. Previous EU projects concerned non-animal and in silico methods for the chemical toxicity assessment, including CAESAR, HEROIC, MODERN (nanoparticle risk), NOMIRACLE, OSIRIS as coordinator, and the on-going SOLUTIONS (human & environmental risk assessment). Other recent grants enabled research into the in-silico screening of endocrine disruptors (UBA) and of non-extractable residues from xenobiotics and their metabolites (CEFIC-LRI), and on in silico structural alerts (German DBU and BfR) as well as chemoassays augmented by experimentally simulating biotransformation (German BMBF project ProHapTox, ongoing) for skin sensitizers.
Gerrit as UFZ PI will coordinate WP4 and will focus scientifically on bioavailability (Task 4.2), QSAR and structural alert (Task 4.5), PBTK (Task 4.4) and DSS (Task 4.7) modelling. He will contribute to WP2 (Data Management), to WP3, WP5 and WP6 regarding the mechanistic selection and QSAR profiling of most suitable MIE-/MOA-specific thyroid disruptors, and also to WP7 (Validation).
