Tanja Pyhäjärvi

PhD, Docent

Population Genomics

Biography

I am an Academy Research Fellow in the Department of Ecology and Genetics.  My research group works on evolutionary genetics and we are interested in various aspects of population genetics and molecular evolution. Genetic basis of environmental adaptation, haploid life stage evolution and effects of natural selection on molecular variation are in our focus. We mostly work with plants: Pinus sylvestris (Scots pine), Arabidopsis lyrata and Betula pendula (Silver Birch).
