Dr. Barrios received his M.D. degree from the Facultad de Medicina, Universidad Nacional Autonoma de Mexico in Mexico City. He then completed a pathology residency at the University Hospitals of Cleveland in Cleveland, Ohio, and a fellowship at Children´s Hospital and National Heart Institute in Mexico City. Dr. Barrios also completed a pulmonary pathology fellowship at the Lyman Duff Laboratory of McGill University and Royal Victoria Hospital in Montreal, Quebec, Canada before returning to the National Heart Institute as a staff pathologist in 1976. He would become chairman of the Department of Pathology there in 1984. Dr. Barrios held faculty appointments at the Universidad Nacional Autonoma de Mexico and as visiting professor before joining the faculty at the Baylor College of Medicine in Houston, Texas as associate professor in the Department of Pathology in 1992. Dr. Barrios received his faculty appointment at the Weill Cornell Medical College in 2005.
