I am a senior researcher in the INVEST Flagship (Department of Social Research), studying parental leave uptake effects on the life-course and how the extended family associates with educational outcomes. Previously, I worked in the Department of Biology on the context-dependence of grandmother effects in pre-industrial Finland.
My current work focuses on life-course outcomes of couples based on their parental leave uptake and following parental leave reforms in Finland (as part of the PREDLIFE project within INVEST). I also have a project working on educational outcomes and how the extended family may influence these. Additionally, I am working on further context-dependence in grandmothering, from evolutionary and demographic angles.
In my curent position, I teach Introduction to R and Event History Analysis course for INVEST. I have previously taught on the Human Evolution and Advanced Evolutionary Biology courses given by the Department of Biology.
