Dr. Rhea’s research interests include antimicrobial resistance, healthcare-associated infections (HAIs), and infectious disease outcomes associated with injection drug use. She serves as a Principal Investigator for the Centers for Disease Control and Prevention (CDC)–funded Modeling Infectious Diseases in Healthcare Network (MInD-Healthcare), using agent-based models to understand the spread of HAIs and antibiotic resistant infections and assess the potential effects of intervention strategies. In addition, Dr. Rhea is Associate Project Director for a National Institutes of Health-funded project to assess prevention and treatment resources for opioid users in western North Carolina and identify ways to improve capacity for these resources in rural areas.
