Lunchon seminar †
We introduce the target papers and/or the content before the presentation. Please contact with Ryu Koharu because some of us will prepare a resume for participants.
Room N356 at Agriculture School of Hokkaido University: 12:00-12:45.
・From July 31st to August 29th, we have summer vacation. The seminar will start again from September 5th!
