MD, Tohoku University, Sendai, Japan, 1986, and PhD, Karolinska Institutet, 1998.

The current position is a senior scientist at Karolinska Institutet, CLINTEC, Transplantation Surgery, Stockholm, Sweden.

I trained as a surgeon at a city hospital and also at the Department of Thoracic Surgery in Japan. The specific interest is transplantation immunology. My research topics are immune responses in pig-to-human xenotransplantation, pancreatic islet transplantation, and tolerance induction in organ transplantation. I am currently involved in a clinical project to induce organ-specific tolerance by cell therapy in deceased donor liver transplantation.
