Research interests

My research interest is in Reproduction Toxicology and Environmental Health with emphasis on metabolism and transport of metals (mercury, iron, lead, and cadmium) and per- and polyfluoralkyl substances (PFAS) across the human placenta. In search of proteins that mediate placental kinetics, i.e., uptake, distribution, biotransformation, and efflux of the substances, we combine Human Biomonitoring and genotyping with basic research on placental in vitro models. The aim is to identify genetic variants related to placental dysfunctions and pregnancy diseases.

Human Biomonitoring, Genotyping, Molecular biology, Cell culture, Placental primary cells, Trace element analysis (AFS, AAS)
