Serhiy Dekhtyar is an assistant professor at ARC. His work concerns risk and protective factors for dementia in a life course perspective. He is also interested in longitudinal evolution of multimorbidity, the coexistence of multiple chronic conditions within the same individual. Dr. Dekhtyar is the principal investigator for the project investigating mental health outcomes in older adults in relation to lifelong socioeconomic disadvantage and multimorbidity financed by the Swedish Research Council for Health and Working Life (FORTE).

Serhiy Dekhtyar obtained his PhD in 2013 from the Centre for Economic Demography at Lund University. During his postdoctoral training at Karolinska Institutet (Department of Clinical Neuroscience, Division of Psychology; Herlitz research group), Serhiy investigated the role of intellectual stimulation over the life course and the risk of dementia disorders in late life. He has also done work on contextual effects in cognitive ageing, as well as gender differences in cognition and their effects on career gender segregation in Sweden.
