Takahashi lab is an open environment with no core time, so students are encouraged to conduct their research based on their motivation and time. Every student belongs to a research group a holding weekly meeting about individual recent progress. There is a monthly meeting, a lab-wide debriefing session, where students give higher quality presentations and learn presentation skills. Students can effectively acquire the abilities of time planning, activity, and communication through all the processes. We also have various events, including regular events such as Hanami in spring, a floating noodle party in summer, Imoni and mountain climbing in fall, etc.
