Hiroki earned his MD in Tohoku University School of Medicine, Japan in 2010. After his clinical internship training, he enrolled in Tohoku University Graduate School of Medicine, Japan and earned his PhD under the supervision of Professor Hideo Harigae and Professor Kazuhiko Igarashi in 2017. His PhD studies focus on the mechanism by which the differentiation and maturation of hematopoietic stem/progenitor cells (HSPCs) are controlled in responding to environmental changes, such as nutritional status and infectious status.

By using novel mice models, he is currently investigating the factors which possess important roles in the maintenance of normal hematopoietic system, in particular the immune system. In addition, as a clinical hematologist, he is now trying to establish the immunomodulatory therapy by targeting these factors.
