William J. Janssen, MD

Special Interests

Clinical Interests

My clinical interests are in critical care medicine and chronic obstructive pulmonary disease. I also specialize in the treatment of septic shock, acute lung injury, and ARDS (acute respiratory distress syndrome).

Research Interests

My research is focused on mechanisms of repair following acute and chronic lung injury. This includes studying how lung collectins influence alveolar macrophage phenotype, function, and fate in healthy lungs and during inflammation. I am also interested in the role that bone-marrow-derived stem cells (including endothelial progenitor cells) play in recovery from lung injury.
