Currently
I am a PhD student at the University of Sheffield, UK. My supervisors are Prof. Nikos Aletras and Prof. Aline Villavicencio. Previously, I was a full-time NLP researcher at Hitachi, Ltd. in Japan. Before that, I was a master’s student at the University of Sheffield, where I obtained an MSc. in Computer Science with Speech and Language Processing (with Distinction).
My curriculum vitae (CV) is available here (Updated on October 4th, 2023).
