He received his Ph.D. in Graduate School of Medicine, University of Tokyo. He is interested in understanding the mechanisms of the development of allergic airway inflammation, especially the effect of various cytokines on dendritic cell functions and antigen-induced immune response, using mouse model. He is interested in the effect of neutrophilic airway inflammation or rhinovirus infection on asthma exacerbation. He is also interested in understanding the mechanisms of allergen immunotherapy. Research Interests: 1. Mechanisms of the development of allergic airway inflammation, 2. Effect of neutrophilic airway inflammation or rhinovirus infection on asthma exacerbation, 3. Mechanisms of allergen immunotherapy.
