[ email | bibliography | personal page ]

My main research activity: Anita Jemec Kokalj is an Assistant Professor in the Biotechnical Faculty of the University of Ljubljana, Slovenia. She has more than 15 years of experience in the field of ecotoxicology, with the major part of her research focused on nanoecotoxicity, in terms of both fate and environmental hazard. In recent years, she has been actively involved in microplastics and nanoplastics research. Her research is focused on the potential effects of materials using different test systems, from cell lines, to aquatic and terrestrial invertebrates, to vertebrate embryos. As well as the classical toxicological endpoints, her interest is to investigate changes at the cellular and subcellular levels, including stress responses, detoxification, and immune responses. She is involved in the development of the assessment criteria for the quality of ecotoxicity data for regulatory purposes.

My main research fields are:

  • emerging contaminants of concern: endocrine disruptors, pesticides, nanomaterials and microplastics
  • aquatic toxicology,
  • terrestrial toxicology,
  • environmental risk assessment,
  • biology of cave and surface freshwater crustaceans.

I was awarded a PhD in Biological Science (2008) from Biotechnical Faculty, University of Ljubljana, Slovenia. The title of the thesis is: Biochemical biomarkers in invertebrates.
