Surgical Research

Dr. Harmon's recent work focuses on using growth factors and techniques of molecular biology to accelerate and improve the quality of wound healing in a variety of tissues.

Dr. Harmon has research interests in the pathophysiology of gastroesophageal diseases. He has publications related to the gastrointestinal organs including the esophagus, stomach, small intestine, and colon. His publications also deal with topics in military medicine especially blast injury. His paper on Zollinger Ellison Syndrome was one of the first to show the importance of removing the tumours and he was the first to observe an endocrine effect of marijuana. His animal studies of GERD (gastro esophageal reflux disease) are extensive and help explain the pathophysiology of this condition.

Dr. Harmon's Surgical Research Laboratory has been a fertile training ground for young investigators. Prospective candidates should email their CV's and a letter of inquiry to Dr. Harmon, (jharmon@jhmi.edu).
