He received his doctoral degree at the University of Texas Medical School at San Antonio and completed his postdoctoral research training in the laboratory of Andrew H. Limper at the Mayo Clinic. Dr. Evans joined the faculty at MD Anderson in 2005 to study the prevention and management of pneumonia in the immunocompromised host. He directs a research program focused on manipulation of lung mucosal defenses to protect against pneumonia. Using a combination of mouse genetics and in vitro modeling, his laboratory has discovered a broadly protective therapeutic that is now in clinical trials.
