My research focuses on the dynamics of long-term environmental changes, varved sediments and diatoms. I am program responsible and also teaching within the environmental and health program.
My research focuses on the study of the complex interactions between a lake's biota (mainly diatoms) and the environment. Most of the research is relying on paleolimnological techniques, which allow reconstructing the environmental histories of lakes, but also investigate the impact of major environmental changes on lake ecosystems. My projects deal with applied aspects of environmental degradation and recovery (e.g. climate, acidification, eutrophication), and more theoretical subjects related to long-term development of lakes. Because historical reconstructions are dependent on an understanding of living biological communities (algae, invertebrates), several projects are also dealing with present-day lake systems in varved lakes, and the linkage between aquatic and terrestrial systems. I have always been keen to develop my paleolimnological research using statistical methods, in order to achieve robust and quantified estimates of past environmental conditions.
