I was born in Kanagawa, Japan, in 1991. In March 2014, I obtained a B.E. degree with highest distinction in Computer and Information Sciences from Tokyo University of Agriculture and Technology, Tokyo, Japan. I also gained an M.E. degree with highest distinction from the same university in March 2015 and graduated one year ahead of the normal schedule. In March 2017, I completed a Ph.D. degree in Electronic and Information Engineering under the supervision of Dr. Shinya Sugiura and Dr. Keiichi Kaneko, as a research fellow of the Japan Society for the Promotion of Science. I am currently an assistant professor in the Graduate School of Information Sciences, Hiroshima City University, Japan.
I have worked on the differential MIMO encoding, which dispenses with the channel estimation overhead of wireless systems. My research topic also includes the index-modulation for millimeter wave, optical, and multicarrier communications. Please check my publications list for further details.
