Policy to give a presentation（日本語）
Policy to give a presentation（日本語）
予定が調整できない等の事情を除き，基本的に全ての講演依頼をお引き受けしています．論文にしていない研究内容についても講演することは可能です．ただし，2023年4月以降は以下の場合を除きます．
原則的にオンライン形式のみでの講演はお引き受けいたしません．これは私自身が対面での講演の方が好みであるためです．対面での講演を遠隔で配信いただくことに関しては特に問題ございません．
3月下旬から4月末にかけては，基本的に講演いたしません．これは自己管理の一環で，私自身が花粉症のため，集中力等が一切維持できなくなるためです．
私より若い方（現時点では，5つ以上学年が異なる方，と位置付けております）との共同研究について講演をご依頼いただいた際には，基本的に若い方にご講演いただきたいと考えております．特に，自身の学生との共同研究については，意欲的な学生については講演する機会を与えたいと考えております．その際，若い方を推薦する可能性もございますが，何卒ご了承くださいませ．
