My researchy focuses on the study of pediatric immunology, with special emphasis on primary immunodeficiency diseases (PIDs). Among many PIDs, I am particularly interested in familial hemophagocytic lymphohistiocytosis and autoinflammatory disorders, diseases characterized by uncontrolled immune responses that result in excessive inflammation and not by susceptibily to infections commonly seen in classical forms of PIDs. By unraveling the pathogenesis of these disorders, I hope to provide new strategies to diagnose and treat the patients.
