Olga Morozova

Olga (Olya) Morozova is an Assistant Professor of Public Health Sciences at the University of Chicago's Biological Sciences Division. She is an infectious disease epidemiologist and public health modeler with expertise in HIV transmission dynamics and substance use disorders.

Education:

• Ph.D. in Epidemiology from Yale University (2018)
• M.S. in Mathematical Modeling in Social Sciences from Kyiv National University, Ukraine
• B.S. in Applied Mathematics from Kyiv National University, Ukraine

Morozova's research focuses on the interaction between HIV and substance use disorders, infectious disease transmission dynamics, and public health modeling. Her methodological interests include causal inference under interference with a focus on contagion and network peer effects. She has conducted significant research in Ukraine, including studies on opioid agonist treatment integration into primary care, HIV prevention strategies among people who inject drugs, and the impact of the Russia-Ukraine war on healthcare delivery. During the pandemic, she developed novel methods to incorporate behavior change metrics into traditional infection transmission modeling, with results used to support decision-makers at Connecticut's governor's office.

Her publication portfolio shows a strong focus on HIV epidemiology in Eastern Europe, substance use disorders, and the intersection of these fields with infectious disease transmission. Recent work increasingly addresses the impact of the Ukraine conflict on public health systems and the long-term effects of COVID-19, particularly among essential workers and vulnerable populations.

Morozova has collaborated extensively with researchers from Ukraine and other international institutions, particularly on studies related to opioid use disorder treatment and HIV prevention in Eastern Europe. Her work often combines mathematical modeling with empirical data collection to evaluate public health interventions and inform policy decisions.
