Dr. Liebler hails from Detroit, MI where she attended medical school at Wayne State University. After coming to the USC Keck School of Medicine in 1999, Dr. Liebler has established herself as a leading educator in lung transplantation and critical care medicine. She was formally the Associate Medical Director for Keck’s Lung Transplantation Program and is currently an attending physician for both LAC+USC Medical Center’s Medical Intensive Care Unit and Keck Hospital of USC Pulmonary and Critical Care Medicine division. In addition to lung transplantation, Dr. Liebler research interests also include lung injury and repair and cell-based treatment of lung diseases.
