Research Interests
My research interests include a focus on: (1) assessing the comparative effectiveness of screening and diagnostic instruments for neuropsychiatric disorders in low and middle income countries; (2) integrating biological markers into clinical and population-based studies to identify factors that contribute to both resilience and risk of psychiatric disorders, (3) applying advanced epidemiologic and statistical methods in psychometric research; and (4) understanding the epidemiology of chronic non-communicable diseases in sub-Saharan Africa and Latin America. I have contributed to the design and execution of large scale biomarker-epidemiologic study of non-communicable disease risk factors in sub-Saharan Africa and South America.  I have also contributed to the design and implementation of a multi-country sleep epidemiology study involving 10,000 university students in Asia, South America and sub-Saharan Africa. Recently, I led a study that evaluated the diagnostic validity of the Patient Health Questionnaire-9 and the Composite International Diagnostic Interview (CIDI) assessment instruments for depression in Addis Ababa, Ethiopia. In addition to my scientific contributions, I have been managing the HSPH Multidisciplinary International Research Training (MIRT/MHIRT) Program (formerly the UW MIRT/MHIRT) for the past ten years.
