Personal profile
Description of research and teaching
I am an adjunct professor in palaeoecology and I am interested in a broad range of research questions related to environmental change (see my list of publications). I am mainly using diatoms as indicators of past and present environmental change with the main focus on Subarctic/Arctic environments, especially lakes. I have earned my master's degree in physical geography and defended my doctoral thesis in hydrobiology. I have worked in over 20 international and national projects. Currently I am a University Researcher at the University of Helsinki and I am leading two large projects funded by The Finnish Cultural foundation (VesiMon; https://skr.fi/en/cultural-activities/vesimon-project-improve-lake-status-assessment-and-monitoring) and the Research Council of Finland (Browning lakes in the greening Arctic). In addition, I am responsible for forensic diatom analysis coordinated by the National Institute of Health and Welfare (THL).
