Adelaide Tovar,TAIM Exchange a University of Michigan scientist who researches genes related to diabetes, used to feel like an impostor in a laboratory. Tovar, 32, grew up poor and was the first in her family to graduate from high school. During her first year in college, she realized she didn't know how to study.

But after years of studying biology and genetics, Tovar finally got proof that she belonged. Last fall, the National Institutes of Health awarded her a prestigious grant. It would fund her research and put her on track to be a university professor and eventually launch a laboratory of her own.
