Dr. Kathryn M. Nowotny's lab focuses on public health interventions aimed at reducing HIV transmission and improving healthcare access for vulnerable populations, particularly those involved in the criminal legal system and survivors of sex trafficking. The research includes innovative telehealth models and community-based outreach programs to enhance the use of HIV prevention services like PrEP and to integrate recovery services for individuals with substance use disorders. Through peer-led interventions and support within syringe service programs, the lab aims to improve outcomes and foster sustained care for individuals facing significant healthcare barriers.
