Suomen lippu Suomi


I am a geoscientist, currently working as an Academy of Finland research fellow at the University of Helsinki. My foremost area of expertise is paleoclimatology, the study of Earth's past climate changes. My recent research focuses on Earth's past warm climate periods and past changes in the Atlantic oceanic circulation.

I am also an active science communicator and popular-science writer.

In my spare time I enjoy rock music, cooking (especially Indian, Italian, and Middle Eastern cuisines), traveling, reading, and long walks.
