Why goyoiraola is fighting geographical bias by collecting microbiome data from Latin American countries

One long-term research goal is to better understand the gut microbiome — the composition and balance of bacteria in the gut — and how it varies across populations, to help treat many conditions. It’s especially important for Latin American countries, because existing human-microbiome databases come from wealthier countries — in North America, Europe and China, especially — where much of the sampling has been done. This leads to bias.
I lead a consortium of scientists in Uruguay, Argentina, Chile, Bolivia, Brazil, Colombia, Ecuador, Mexico, Paraguay, Costa Rica, Peru and French Guiana. We gather data on microbiomes in these incredibly heterogeneous countries. I see it as a puzzle; we need to find pieces from across the region before we can put the picture together.
My long-term dream is to help other scientific communities to collect and analyse microbiome data, so that medical interventions make sense for local populations, diets and cultures. Once I’ve done that, perhaps I can go back to cooking — one of my hobbies — or growing vegetables. My father is a farmer in Cardona in the southwest of Uruguay, and I visit often. It’s satisfying doing worthwhile research that’s specific to this continent.
