Lung specialist works with a wide range of patients


Lung disease specialist, Mario Castro, MD, MPH, is a professor of medicine and of pediatrics.

Mario Castro, MD, MPH, is a professor of medicine and pediatrics and the director of the Asthma and Airway Translational Research Unit, which coordinates Washington University School of Medicine’s asthma research. He is involved in more than 20 ongoing studies focusing on the genetic, biological and immunological origins of asthma and how to reduce the suffering and death associated with the disease.

Born in Matanzas, Cuba, and raised in Kansas City, Mo., Castro attended medical school at the University of Missouri-Kansas City and completed the BA/MD program. At Washington University School of Medicine, Castro works with people experiencing a wide range of asthma symptoms, including people who are very disabled by their condition and elite athletes whose asthma limits their performance.

“What’s always been joyful to me about taking care of asthma patients is that no matter their initial condition, I can usually make them feel better and allow them to function at a much higher level,” Castro says. “I also like the challenge of working to prevent this disease,” he says. “That’s one of those frontiers we haven’t crossed yet, and, in my lifetime, I believe that we can achieve it.”
