PhD Position in Aquatic Toxicology of PFAS (f/m/d)
Stellenanzeige merkenStellenanzeige teilen
Are you passionate about environmental toxicology and eager to unravel the effects of PFAS on aquatic organisms? At BioQuant of Heidelberg University, a PhD position is available at the earliest possible date in the Junior Research Group Gölz. This interdisciplinary research project explores the effects and mechanisms of PFAS at different biological levels, with a special focus on cardiovascular toxicity and additional interest in endocrine-related mechanisms. By working at the intersection of human and environmental toxicology, you will have the opportunity to advance Adverse Outcome Pathways (AOPs) and support the development of New Approach Methods (NAMs), thereby contributing to a more sustainable and responsible management of environmental chemicals.
- Job-ID: V000015436

- Anstellungsart: Voll-/ Teilzeit
- Veröffentlicht: 11.03.2026
Research Areas and Methodological Focus
1. PFAS Toxicity and Underlying Mechanisms in Zebrafish Embryos
- Analysis of PFAS effects across different biological levels using molecular biology techniques such as gene expression analysis and transcriptomics, as well as histological methods
- Physiological investigations of cardiovascular effects, including heart rate measurements and live imaging
- Behavioral analyses to assess neurotoxicity and developmental impairment, including swimming behavior and light response assays
2. Development of Ecotoxicological Endpoints for PFAS Effects
- Application of current OECD fish test guidelines to evaluate PFAS effects in aquatic model systems, particularly OECD TG 236 (Zebrafish FET Test)
- Investigation of endpoints for the detection of cardiotoxicity, neurotoxicity and endocrine disruption induced by PFAS
3. AOP Development and Interdisciplinary Research
- Investigation of causal relationships across different biological levels
- Support for the further development of Adverse Outcome Pathways (AOPs) in toxicology
