About me

I am a principal investigator of the Vitality 90+ Study, which is a multidisciplinary research project on health, functioning, living conditions, quality of life and care needs among the oldest old individuals. My background is in public health and I got my PhD in health sciences in 2017 at the University of Tampere. In my PhD theses, I examined socioeconomic inequalities in health, functioning, mortality and round-the-clock care in people aged 90+. More recently, my research has focused on the societal consequences of lengthening old age. In particular, I have examined time trends in health expectancies and health inequalities and predictors of health and social service use. In addition, I am interested in air temperature-related public health effects such as quality of life, health care use and mortality among older people.
