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).
