She is currently a DPhil candidate in the Department of Social Policy and Intervention, with a working title 'Disrupting compounding challenges of gender, sexual violence and HIV among adolescents living in South Africa: Ensuring no one is Left Behind'.
Nontokozo has served as a panel expert on sexual and reproductive health and rights for adolescents, addressing policymakers at the South African Development Community (SADC) regional meetings and African Union meetings. Her collaborative work with UNICEF Eastern and Southern Africa includes multiple policy briefs on drivers and mitigators of adolescent HIV risk, including the negative impact of violence on ART adherence.
