Description of research and teaching
My PhD research focused on biogenic sea-ice proxies, namely diatoms, dinoflagellate cysts and highly branched isoprenoid lipids. I am broadly interested in the Arctic region, and so far my studies have focused in Greenlandic coastal regions as well as Hudson Bay in Canada.
I am particularly interested in the Arctic environmental change and sea-ice decline and their impacts on the ecosystems and biodiversity. While I have most recently worked with sea-ice, water column, sediment trap and surface sediment samples, I have also previously worked with sediment core data.
