Work at AHRI 

Nuala’s work at AHRI began in 2002 as site PI for the Microbicide Development Programme. Interested primarily in HIV and sexual behaviour change, Nuala has collaborated with AHRI on a diverse range of intervention, clinical and population-based studies. With a Wellcome Trust Research Career  Development Fellowship, at AHRI, 2008-2015, her research expanded to explore the impact of antiretroviral treatment on risky sexual behaviours and onward transmission of HIV and the evaluation of HIV treatment and prevention strategies, including the promotion of HIV testing to reduce the onward transmission of HIV. More recently, Nuala has concentrated on intervention development and evaluation research. At AHRI she is involved in developing and evaluating sexual health and HIV prevention interventions for adolescents and young adults with other faculty – Shahmanesh (PI), Chimbindi, Harling and Seeley. With other South African collaborators in KwaZulu-Natal and Western Cape, she undertakes research to improve couples health and wellbeing.
