Your personal sphere of influence:You will join the Department of Environmental Geosciences (EDGE) at the Centre for Microbiology and Environmental Systems Science (CeMESS) to investigate p phenylenediamine (PPD) tire antioxidants and their quinone transformation products (PPD Qs).The project you will be working on studies tire antioxidant chemicals (PPDs) and their quinone products (PPD‑Qs) released by tire and road wear, and investigates how their properties affect transport across cell membranes, binding to blood proteins, and effects on human cells. The objectives are to measure passive transport and distribution (including plasma protein and membrane lipid binding); to quantify cytotoxicity in human intestinal and lung cell models; and to determine whether the observed effects fit baseline (narcosis) toxicity or reflect specific mechanism. Using a set of PPDs and PPD‑Qs, the work links in vitro effect levels to plausible human exposures and compares current antiozonants with potential replacements.Your future tasks:You actively participate in research, teaching, and administration, which means that you will:Plan and execute experiments to quantify passive transport, membrane partitioning, and plasma protein binding for selected PPDs and PPD Qs, ensuring appropriate test conditions and quality control.Generate concentration–response data in intestinal and lung cell models to compare toxicity across ingestion and inhalation relevant tissues.Perform mechanistic studies to differentiate baseline toxicity from specific mode of toxic action.Analyze how lipophilicity and electrophilicity relate to transport, binding, and cellular outcomes.Manage data analysis and documentation; contribute to manuscripts and presentations.Progress your dissertation; contribute to teaching and administrative tasks; supervise undergraduate/master’s students as appropriate. This is part of your personality:M.Sc. in toxicology, environmental chemistry, environmental sciences, or a related field.Excellent written and spoken English (at least level C1).Laboratory experience.Experience with LC-MS/MS.Ability to perform concentration–response testing and statistical analyses.Familiarity with cell culturing, membrane transport assays, and/or protein binding is an advantage.Strong interest in membrane-molecule interactions and mechanistic toxicology; motivation to link physicochemical properties to biological effects.Readiness to implement and standardize assays across models.Willingness to develop skills in data analysis and research data management.Curious, independent, proactive, and highly motivated personality. What we offer:Employment: The employment duration is 3 years.
