I am a senior lecturer, which roughly corresponds to a reader in British academic system, an assistant professor with tenure in American academic system, of  Department of Computer Science, Faculty of Informatics, Shizuoka Institute of Science and Technology, which is located in about 200km (120mi.) west of Tokyo. I am also a visiting researcher at AIRC, AIST, Japan, and an ACT-I researcher.

My research interests include natural language processing (NLP), especially in educational NLP using item response theory (IRT) and machine learning (ML).

Previously, I was a researcher at the Artificial Intelligence Research Center (AIRC), National Institute of Advanced Industrial Science and Technology (AIST) in Tokyo, Japan. There, I studied natural language understanding.

Before that, I was a project assistant professor at Graduate School of System Design, Tokyo Metropolitan University, a researcher at National Institute of Information and Communications Technology, a postdoc at National Institute of Informatics (JSPS PD, in Prof. Miyao group), in reverse chronological order. I obtained my Ph.D. (Information Science and Technology) at the University of Tokyo, supervised by Prof. Hiroshi Nakagawa, in September 2013.
