    Research interests

    I am a paleoclimatologist and Quaternary geologist interested in understanding long-term Arctic climate change. My research focuses on paleoclimate reconstruction, mainly using organic geochemical and stable isotope proxies.

    Keywords: Arctic, Holocene, paleoclimate, climate proxies, lake sediments, organic geochemistry, biomarkers, stable isotopes

    Teaching

    My teaching experience includes classroom and lab exercises, lectures, and field teaching on bachelor's and master's/PhD level, as well as MSc student supervision. I teach on the following courses:
