A social scientist by training, Dr. Corneli has conducted qualitative and mixed-method research primarily in biomedical HIV prevention and bioethics in multiple countries in sub-Saharan Africa, the Middle East, South and Southeast Asia, and in the U.S.  A significant portion of her research portfolio has focused on engaging patients/participants and other key stakeholders in qualitative research to inform clinical research, socio-behavioral interventions, and material and scale/questionnaire development as well as to assess participant perceptions of intervention/clinical trial implementation. Her HIV-related research focuses on identifying evidence-based strategies for linking populations at HIV risk to PrEP care, support PrEP adherence to achieve protective levels, and keep clients engaged in PrEP care for as long as their HIV risk persists. Her research in bioethics has explored innovative methods for improving informed consent comprehension and shortening consent forms, the acceptability of informed assent, and the functioning of research ethics committees.
