Olga is a Research Scientist at the ISPH and an NIH Fogarty Global Health Fellow with the GHESKIO Centers in Port-au-Prince, Haiti. With training in epidemiology and biostatistical methods, her expertise includes quantitative and qualitative study design; data collection; and analysis of surveillance, service delivery, and survey data in both domestic and lower- and middle-income country settings (primarily Ethiopia, Tanzania, and Haiti). Most recently, Olga has led analyses for the World Health Organization on the impact of expanding antiretroviral treatment (ART) eligibility guidelines on the timeliness of ART initiation across 21 countries and has designed a population-representative household- and individual-level demographic and health survey for an urban slum setting in Haiti. Her subject matter expertise includes HIV; care continuum among HIV and STI co-infected patients; foodborne disease; hypertension; and health in slum settings. She is fluent in Spanish, German, and Polish, and proficient in Portuguese, French, and Ukrainian.

Olga is an Epidemiology doctoral candidate at CUNY School of Public Health & Health Policy under the mentorship of Dr Nash. Her dissertation examines hypertension patterns in a slum community and a cohort of HIV patients in Port-au-Prince, Haiti.
