I completed my Ph.D. in electronic and electrical engineering from the University of the Ryukyus in 2015. My research in the Nanoparticle by Design Unit in OIST was focused on the understanding of gas phase synthesized nanoparticle effect on semiconducting nanowires based micro devices. My current research interest focuses on the effect of nanocarbon materials on graphene-based micro/nano devices and their applicability in gas sensing, bio sensing and optoelectronics.

I studied applied chemistry and organic chemistry during my bachelor and master stages, respectively. Then in Jan 2020, I received my doctoral degree from University of Macau with a concentration in biomedical sciences. Organic molecule synthesis is the foundation of my research. Pursuing a suitable application for useful material is always the goal. My studies cover linear and nonlinear optics, chiroptics, bioimaging and sensing. My current research interests focus on the synthesis of polycyclic aromatic hydrocarbons (PAHs) and the exploration of their applications in the optical/biological fields.
