About

I’m Chihiro Taguchi, a full-time language lover. I’m a PhD student in Computer Science and Engineering (CSE) at the University of Notre Dame, USA, as part of the Natural Language Processing group led by Dr. David Chiang.

My name in Japanese is 田口智大, and roughly speaking, it’s pronounced as /tágɯ̀t͡ɕì t͡ɕìçíɾó/ (á: high pitch, à: low pitch).
