Information to students
If you are interested in studying at our lab, please check this page which summarizes how to choose your supervisor and our research style in this lab. If you wish to research in this lab, please contact Jun Kurihara before applying the admission exam. I believe that we should have a chat (F2F or online) beforehand in order to have good research topics at this lab and avoid any misunderstanding on our research.
