I am ecotoxicologist who completed my PhD degree at the department in September 2018.
I have been interested in how life history affects pollutant levels in organisms. Does the energy an individual put towards growth or reproduction lead to different tissue concentrations of pollutants in the environment? In many species of marine mammals, we find lower levels of pollutants in females than in males because females can offload contaminants to their offspring.
What are the processes behind this? Which factors influence life history strategies and consequently alter pollutant levels? I have used different methods (meta-analysis, field and lab) to answer some of these questions. Taxa have included pinnipeds (seals, sea lions and walruses), seabirds and Arctic-breeding geese. I have investigated reproductive investment in mothers, timing of migration and energy source. In summer 2016, I travelled to Kongsfjorden in Svalbard to look at barnacle geese (Branta leucopsis) and their eggs. This was followed by pollutant analysis which I carried out in Tromsø January-March 2017.
My research interests are in the fields of ecotoxicology, life history theory and statistical modelling.
