Message

Having been bearing global health as one of practical sciences in mind, I worked at a variety of organizations both as a practitioner and as a researcher. Throughout my professional career, I have learned that practicing and researching are key two wheels of a vehicle that takes us to healthier and more productive world. My research interests are diverse, yet likely focused more on health system strengthening. I look forward to doing research with you not only on important global health agenda but also on neglected global health issues, for identifying their effective and feasible solutions in an evidenced-based manner.
