Upon joining IFTF in 2007, Vivian quickly became the voice of the Health Horizons Program in the blogosphere, writing about trends in the global health economy and other interesting health-related news. As a researcher, Vivian has explored how social networking platforms have contributed to the emergence of collective action groups centered around shared health concerns.
