Personal profile
Description of research and teaching
I am a palaeoecologist, interested in the reconstruction of past climate and environments using both marine and freshwater sediment proxy records. My expertise include marine, brackish and freshwater diatom taxonomy and ecology, and sediment biomarkers (especially IP25), with a special interest is proxy evaluation and development. I have both led and been involved in several international projects including research topics such as the recent eutrophication history of the Baltic Sea (MOLTEN, DETECT, DEFINE), Late-Pleniglacial climate change in the southern Alps (Academy of Finland Postdoctoral Fellowship to work at the Mondsee Institute for Limnology, Austria), Arctic sea ice and ocean variability around Greenland and in the Labrador Sea (incl. Marie Curie Individual Fellowship CLIMICE, partly based at LOCEAN, Paris), and the effects of groundwater phosphorus concentrations on lake trophy. My recent interest in Arctic environmental change began during the 8 years (2007-2015) based at the Geological Survey of Denmark and Greenland (GEUS).
