Summary: 

Some give a tutorial lecture on a topic related to his/her research.

Each of the other attendees gives a lecture presentation on his/her own research.

If you are assigned to one of the poster sessions, please prepare your poster in B1 size.  

Every student is required to submit a report on your/others' presentation to the supervisor after the lab retreat.
