The laboratory is investigating the immune mechanisms of cellular recognition and histocompatibility. This includes immune responses in transplantation with an emphasis on stem cell transplantation. We study basic research on understanding immune mechanisms into translational medical research. We work on the immune system and stem cells with diverse organisms such as humans, tunicates, planarians and corals. We even translate our findings to ecological issues such as the use of stem cell transplantation for the preservation of coral reefs.
