FinnBrain Birth Cohort Study; Centre for Population Health Research

I did my PhD within the field of psychiatric epidemiology and adolescent depression. During by PhD studies I also was involved in clinical epidemiological studies on adolescent mood disorders. In 2010, we established a birth cohort, the FinnBrain Birth Cohort Study, with the main aim of investigating the how early life and prenatal stress shape brain developmental trajectories. I am currently (since July 2024) the PI pf the cohort. My own research activity within the larger cohort is focused on the development of the gut-brain axis and child psychosocial development and the role of diverse prenatal adn early life exposures in these processes. My activity as a supervisor is also multidisciplinary as the PhD candidates represent, for example, variety of fields of medicine and psychology. I started in the tenure track position at the Centre for Population Health Research in Jan 2021 and continued as a professor of population health research, starting Octoberg 2023.
