Dr. Van Zyl conducted several studies on new strategies to improve the identification of persons unaware of their HIV-1 infection and successfully link them to HIV testing, treatment, and prevention interventions.

His interest in prevention research also includes chronic disease and health disparities. His research interest in child welfare focusses on the prevention of child abuse and neglect, child welfare practice models and quality improvement in social service delivery. He led initiatives to curtail the crises of over-crowding in prisons and collaborated across sectors in advancing implementation science.  His work on measurement impacted various fields of practice including corrections, education, prevention of behavioral problems in young children, risk reduction, and organizational change.
