Description of research and teaching
As a paleoecologist, my research interests focus on past climate and ecosystem changes, from species to ecosystems and from seasonal to millennial time-scales. I am particularly interested in the interplay of climate and biological associations at high latitudes. My current research focuses on Arctic sea-ice changes, primary productivity and carbon cycling in high-latitude lakes and seas, as well as Holocene and Late Quaternary climate and vegetation patterns. The methods include the analysis of paleoarchives (microfossils, biomarkers, stable isotopes) combined with numerical analysis and modelling.
