GEMINI stands for Generational Differences in Environmental Exposures caused by Migration: Impact on Incidence of Inflammatory Disease. It describes a problem in the South Asian Canadian communities. These communities are experiencing a dramatic increase in chronic inflammatory disease incidence upon exposure to the North American environment. At the University of Toronto, a team of scientists, funded by the Connaught Global Challenge and CIHR, are investigating how the microbiome might change when people migrate from South Asia to Toronto. The team will look at how the microbiome is altered in response to global migration and how this could lead to chronic disease.
