Research Interests

Dr. Tanaka’s research focuses has mainly focused on coagulation management, blood-less surgery and transfusion as well as clinical outcomes in the setting of cardiovascular surgery. I have participated in both preclinical and clinical studies of novel agents that modulate coagulation, and coagulation monitoring devices. The main focus is to evaluate the dynamic balance of thrombin generation during liver transplantation, and after cardiopulmonary bypass (CPB). To this end, multi-modal approaches to coagulation assessments are utilized; viscoelastic coagulation monitoring devices, fluorogenic thrombin generation assay, flow chamber system, and computer simulation model.
