Communications & Public Relations Committee
The University of Tokyo's Graduate School of Science and Faculty of Science held the "The University of Tokyo School of Science Image Contest 2023" from May 26 to July 25, 2023, to capture a moment of daily research and educational activities and compete in their beauty.
The image contest had been held as part of the Open Campus, but this year it was held independently again because the Open Campus was held online.
This year we received 30 entries from science students, faculty, and campus staff.
Voting was conducted by the constituent members of the Faculty of Science Communications & Public Relations Committee, and the top three entries receiving the most votes were selected for the Excellence Awards.
The Excellence Award winners will receive a certificate of commendation and a book token as a prize.
Some of the entries, including the Excellence Award winners, will be published in the Image Bank of the Faculty of Science of the University of Tokyo.
The image contest will be held again next year and beyond.
The warm heart of worms" by Shinichi Miyazaki, Assistant Professor, Sleep Physiology Laboratory, Department of Biological Sciences
