    Collapse overview
    Olga (Olya) Morozova is an Assistant Professor of Public Health Sciences. She is an infectious disease epidemiologist and a public health modeler. Her research focuses on interaction between HIV and substance use disorders, as well as infectious disease transmission more broadly. Dr. Morozova conducted studies to evaluate strategies to expand access to and uptake of opioid agonist treatment in Ukraine. She piloted studies of primary healthcare-based integrated care for people with opioid use disorder in Ukraine and conducted model-based policy and cost-effectiveness evaluation of treatment scale-up strategies. Dr. Morozova's COVID-19 modeling work during the pandemic involved novel methods to incorporate behavior change metrics in traditional infection transmission modeling. Results of her modeling work were used to support decision-makers at Connecticut's governor’s office. Dr. Morozova is also interested in quantitative methods in infectious disease epidemiology, in particular causal inference in the presence of contagion. Her work contributed to a better understanding of the properties of traditional vaccine effect estimates under various study designs.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
