The Unit hosts researchers and groups conducting research in life course epidemiology, genetic, molecular and psychiatric epidemiology, occupational, environmental and oral health, as well as health services.

The doctoral researcher position is supported by Health Dimensions, a multidisciplinary research initiative funded by the Research Council of Finland. Health Dimensions explores the complex, multidimensional nature of human health, with the aim to prevent chronic diseases and multimorbidity through a new level of understanding and acting on these dimensions - molecular, physiological, environmental, behavioural and societal mechanisms across the life course.

About the job

The focus of the doctoral research is to examine the roles of early life course stress and adversity in the development of multimorbidity (e.g. the co-occurrence of physical diseases with mental health conditions). The research will use data from birth cohort studies (e.g. Northern Finland Birth Cohorts 1966 and 1986) and/or longitudinal datasets from nationwide health and healthcare registers and sociodemographic data.

The key duties and responsibilities of the doctoral researcher candidate will include

• Cleaning and management of health and related data from longitudinal cohort studies and/or health and other registers
• Using advanced statistical modelling to examine the development and risks of multimorbidity, using large and complex health data
• Writing scientific articles and submitting these for peer review and publication
• Presenting research findings in scientific meetings and conferences
• Working with the other research group members in data analysis and management, and producing research outputs
