The Department of Public Health Sciences comprises a wide field of research on public health. The Department was created in 2018, when Centre for Health Equity Studies (CHESS) merged with Centre for Social Research on Alcohol and Drugs (SoRAD), a merger that strengthened social science research on public health at Stockholm University. SoRAD's research is focused on alcohol, drugs and gambling. Research at CHESS is examining how social factors as well as societal structures and processes contribute to ill health and disease. Both have also received major, competitive funding from the leading research financiers in the field.
