My research interests are focused on how data (stable isotopes and elemental ratios) on individuals and populations from different trophic levels (algae to fish) from long-term time series in different areas of the Baltic Sea can be used to validate large scale models, e.g. through bioenergetics models. Stable isotopes and elemental ratios give information on changes in diet (in consumers), habitat use and nutrient cycling over time. The data can in turn be scaled up geographically using habitat/species distribution models.

I collaborate with the Swedish Natural History Museum and their Environmental specimen bank and contract holders of various monitoring programs to analyze preserved samples of stable isotopes and elemental ratios.
