PhD Student in Chemistry

The Helmholtz Centre for Environmental Research (UFZ) with its 1,100 employees has gained an excellent reputation as an international competence centre for environmental sciences. We are part of the largest scientific organisation in Germany, the Helmholtz association. Our mission: Our research seeks to find a balance between social development and the long-term protection of our natural resources.

The EU project ERGO (Endocrine Guideline Optimization) has started on 1 January 2019 and covers 16 partners from nine countries including the USA. It aims at improving the ha­zard and risk assessment of thyroid disrupting compounds (TDCs). A primary goal is to introduce methods for extrapolating TDC effects across vertebrates as well as from fish or amphibian to human. To this end, the project explores and applies thyroid-related bio­mar­kers, apical endpoints, and in par­ti­cular non-animal in vitro and in silico information. Our fo­cus is the impact of TDCs on the HPT (hypothalamus-pituitary-thyroid) axis, employing an AOP (adverse out­come pathway) frame­work addressed through an IATA (integrated ap­proach to testing and as­sessment) scheme.

The UFZ Department of Ecological Chemistry undertakes mechanistic research into mo­lecular toxicology and chemodynamics, and contributes to ERGO through the fol­low­ing major tasks: TDC bioavailability profiling, PBTK (physiologically based toxicokinetics) model­ling for rat and fish, in vitro biotransformation in S9 enzyme assays, 3D ligand-receptor bind­ing and QSAR modelling, and across-project database maintenance. 

As from now, the following position can be filled:
