I obtained M.D. degree from Yamagata University in Japan, and then I was trained as a resident of internal medicine for two years and as a fellow of respiratory medicine for 3 years. Thereafter, I entered the graduate school of medicine at the University of Tokyo and have been a Ph.D. candidate. I had a great interest in the pathogenesis of bronchiectasis and applied for Dr. Boucher's lab to study the pathophysiology of mucociliary clearance (MCC) system. At present, I have been engaged in the research about how MCC is regulated to maintain lung homeostasis and how it fails in disease as a postdoctoral research associate at the University of North Carolina at Chapel Hill.
