Message to Students

Approximately 425 million adults have diabetes. Our goal is to elucidate pathophysiology of diabetes for development of novel treatment. Our research projects include study of insulin-secreting pancreatic beta-cell biology, utilizing various genetically engineered mice and comprehensive gene expression analysis. We are recruiting graduate students to work together in new research facility here in IUHW.

Research Theme

Elucidation of molecular mechanism regulating development, differentiation and regeneration of pancreatic beta-cells.
Uncovering pathophysiology of diabetes for novel treatment
