Dr. Elizabeth Barnby didn't attend The University of Alabama in Huntsville (UAH) so she could get a job; she already had one as an emergency room nurse. She attended so that she could learn more about Tyrosinemia type 1 (TT1), a rare and often fatal metabolic disorder that affects 1 in every 50,000 babies born in the U.S. Dr. Barnby, it turns out, has two children with TT1. She's also now an assistant professor and the undergraduate program director of UAH's College of Nursing. But when she and her husband moved to Huntsville in 2009, all she wanted to do was help her son and daughter.
