(2017) Genetic structure of Finland before 1950s

Finland 100 years - special stamp

Research

I work with statistical and population genetics. In particular, methodologies related to

genome-wide association studies (both common and rare variants; fine-mapping, multivariate phenotypes).
accounting for heterogeneity across populations/phenotypes/tissues etc.
population genetics in Finland and its application to studies of complex diseases and traits (and stamps!).

I am a member of the Academy of Finland Centre of Excellence in Complex Disease Genetics 2018-2025.

Teaching

I have a title of Docent in Statistics at the Faculty of Science, University of Helsinki, Finland.

Msc programme in Mathematics and Statistics, University of Helsinki

Msc programme in Life Science Informatics, University of Helsinki

Degree programme in Medicine and Dentistry, University of Helsinki

Supervision
