Research is ongoing on the environmental, forensic and analytical chemistry of established (“legacy”) and emerging organic contaminants in wildlife and fish and their aquatic ecosystems. Bioaccumulation, fate, trophodynamics, and spatial and temporal trends are also studied on established and emerging contaminants and metabolites in wildlife (e.g., top predators), food webs, and aquatic ecosystems (e.g., Arctic and Great Lakes). Activities also include mechanistic and comparative biotransformation and pharmaco( toxico)kinetics of contaminants in wildlife and fish. Finally, research is ongoing on species- and ecosystem-specific ecotoxicology and effects of contaminant and metabolite exposure (e.g., endocrine disruption) and assessments.
My research focuses on contaminant levels and effects in Arctic mammals, seals, Arctic foxes and polar bears. I’m interested about how ecological and climate-driven factors affect time- and geographical trends of contaminants. On contaminant effect side, I’m particularly interested on integrating different research fields including physiology, ecology, molecular biology and chemistry to understand how multiple stressors (contaminants and changing climate) affect Arctic animals.
Biological effects of petroleum related contaminants on Arctic marine species with focus on bioenergetics, lipid homeostasis, reproduction and other physiological processes crucial for survival and fitness in Arctic environments; baseline biology and life cycle strategies of Arctic organisms, development of tools for monitoring the effects of oil in Arctic organisms.
As an ecotoxicologist my research focuses on understanding mechanisms and processes for contaminant distribution and accumulation in the environment. This includes the influence of food web ecology, migration, life history traits, and biogeochemistry on (re)distribution of contaminants in the context of a changing climate.
My research is oriented towards Arctic marine food webs, large lake food webs in Norway and Italy, and terrestrial sub-tropical forest distribution of contaminants. Chemicals of interest include both legacy and emerging contaminants.
