Stephen B Liggett M.D.

Academic Title: Adjunct Professor
Primary Appointment: Medicine
Phone: (410) 328-2488

Personal History:

Dr. Liggett obtained a B.S. in Physics from the Georgia Institute of Technology and an M.D. from the University of Miami School of Medicine. He served an Internship, Residency (Internal Medicine) and Fellowship (Pulmonary, Critical Care Medicine) at Washington University School of Medicine/Barnes Hospital in St. Louis. These were followed by a four year, laboratory-based post-doctoral fellowship at the Howard Hughes Medical Institute at Duke University in the laboratory of Robert Lefkowitz. He subsequently became an Assistant Professor of Medicine and Pharmacology at Duke University, and then Professor of Medicine, Pharmacology and Molecular Genetics at the University of Cincinnati College of Medicine, where he was also Director of Pulmonary and Critical Care Medicine. After 13 years as Division Director, he became the Taylor Endowed Professor of Medicine and Director of the Cardiopulmonary Research Center at UC, where he concentrated on his basic and translational research programs.
