His major clinical interests include pneumonia, adult cystic fibrosis, and sepsis. His research interests are primarily directed at (1) understanding normal pulmonary host defense mechanisms, (2) defining how disease states undermine and disrupt these defense mechanisms, and (3) determining the potential of biological response modifiers to provide innovative approaches to both the prevention and treatment of pulmonary infections.
