RTI International

RTI International is an independent, nonprofit research institute dedicated to improving the human condition with a mission to address the world's most critical problems with science-based solutions in pursuit of a better future. Within RTI International, the Women’s Global Health Imperative (WGHI) is a group of researchers who have a wide range of expertise including biomedical prevention, sociobehavioral research, mixed-methods, community-engaged research, adolescent health, and implementation science. Research conducted by WGHI informs the design, implementation and scale-up of new programs, monitoring and evaluation systems, and health policies around the world—particularly as they pertain to addressing health inequities. 

WGHI researchers at RTI play a key role with the D2D hub within MATRIX. Alexandra Minnis co-leads Pillar 2 of D2D with Leila Mansoor of CAPRISA. Together, they seek to drive excellence in sociobehavioral research conducted within MATRIX clinical trials by harmonizing methods where possible to standardize across trials and products, while adapting methods and instruments as appropriate to meet the specific needs of each study.
