Message

As a clinician with researchers’ eyes, we are conducting research that can contribute to practical use for patients based on clinical questions as a rheumatologist. In order to solve the unmet medical needs of autoimmune diseases and autoinflammatory diseases which are regarded as rare intractable diseases, we are looking for fellows who can study together.
