Dr. Horvat Davey is an Instructor at the Frances Payne Bolton School of Nursing at Case Western Reserve University. She is a nurse scientist interested in symptom science, specifically examining the role exercise and biomarkers play in symptoms in order to mitigate symptom burden and improve quality of life for individuals suffering from comorbid conditions, including people with HIV (PWH). Her recent work (K23NR019744) investigates sleep hygiene in older PWH and characterizes the effects of two exercise interventions, high-intensity interval training (HIIT) and continuous moderate-intensity exercise (CME), on sleep quality in older PWH, as well as examines the underlying mechanism of inflammation as it relates to sleep in older PWH. She is a co-investigator for the PROSPER-HIV study, which examines the relationship between exercise and diet intake and the symptom experience in adults living with HIV. Dr. Horvat Davey’s work has been funded by the National Institute of Nursing Research, American Nurses Foundation, as well as private foundations.
