My main research activities involve use of epidemiological and molecular biological approaches to understand the etiology/determinants of disease development and health outcomes/prognosis of diseases, including cancer, trauma-related psychiatric and somatic illnesses, and women mood disorders. My recent research focuses on perinatal maternal and paternal mental health. Key projects investigate perinatal mental health related risk factors and health consequences, including treatment-resistant perinatal depression in women, perinatal suicidal behavior, correlation between perinatal depression and cardiovascular diseases, and psychiatric disorders affecting fathers during and after pregnancy.
