Academic Achievements & Community Involvement
Clinical Care
Overview
Genta Ishikawa, MD, is a pulmonologist who cares for people with interstitial lung disease, including pulmonary fibrosis, a form of lung scarring. He also provides critical care support for patients who experience severe respiratory challenges.
As an instructor at Yale School of Medicine, Dr. Ishikawa studies how nerve-derived chemicals such as noradrenaline influence lung scarring, with the goal of discovering new ways to slow or halt disease progression.
Dr. Ishikawa earned his medical degree from Hokkaido University in Japan and completed a master of public health at Emory University. He went on to finish a residency in internal medicine and a fellowship in pulmonary, critical care, and sleep medicine at Mount Sinai in New York, followed by a postdoctoral fellowship at Yale School of Medicine.
