UH-AORI Symposium

Some members of Yokoyama lab participated in the Hawaii–AORI Symposium held from October 7 to 10.

Yusuke and Shoko gave oral presentations, while Bethany, Miya, and Shunsuke presented posters.

At the icebreaker dinner on the 7th, we had lively conversations with many professors and students over delicious Italian food and wine. Miya even found a new collaborator interested in analyzing the intestines of her abalone shells.

🍕めっちゃうまい！

On the 8th and 9th, a series of oral and poster sessions took place at AORI. The topics were diverse and covered various aspects of marine science, though less focused on geology this time.

During the banquet on the 8th, we enjoyed an excellent buffet. It was a great chance to reconnect with familiar faces (for the professors), make new friends, and chat about science, hobbies, and sports.

The final day was left open for lab visits and informal seminars. Our lab was delighted to host Steven, Sara, and Samuel, who shared their research with us. We also presented our own work and had engaging discussions afterward. Later, Steven expressed interest in visiting the community garden Miya has been working on, so she brought him, Sara, Samuel, and Yahagi-sensei to see her “secret garden.”

Overall, it was a fun and fruitful week full of scientific exchange, casual conversations, delicious food, and both old and new friendships.
