About student application: We receive many spam-like e-mails which are often too general and naive, like "I want to study programming/software engineering/computer science" or "I am good at C/C++/Java" for example. If you are interested in joining our research group, please read and follow the instructions by our ex-professor (but contact me, not him, if you are applying for Tohoku, not Tokyo).
The following information is obsolete. See the official page of the university and researchmap for more (or less) up-to-date data.
