iGEM Qdai 2020 Team Attributions

Wet lab

The team was led by Hiromu Inoue, and consisted of members Haruki Koyama, Shino Suda, Jiaxin Wu, and Haruka Oishi. The wet lab team designed the plasmids containing ppk, relA and phnCDE. They are working hard to construct them right now.

Human Practice

The team consisted of members Haruki Koyama, Kenta Motoyashiki, Kento Tsuruzoe, Shino Suda, Haruka Oishi and Ryosuke Kita. They contacted and sought advice from a lot of experts whose feedback helped us think of advantages and disadvantages of our project.


The team was led by Haruki Koyama. He constructed mathematical models to simulate the total concentration of phosphorus using the plasmid we designed.


The team was led by Ryosuke Kita and consisted of members Haruka Oishi, Haruki Koyama, Shino Suda and Jiaxin Wu. The team designed, illustrated, coded a wiki page and documented our project.
And it was created with the divine advice of Sobasssy, the God of Programming and Machine Learning at Kyushu University.


The Marketing Team was led by Haruki Koyama and consisted of member Shino Suda. Their work attained sponsors and helped our project financially.


The team was led by Haruki Koyama. He came up with a business model for potential applications in the real world.

Science Communication

The team was led by Tamon Matsuzawa and consisted of members Shino Suda, Yasunori Toji, Kenta Motoyashiki, Kento Tsuruzoe, Kenta Takemori and Hiromu Inoue. The team organized an educational event for high school students, which will be held in November, and created educational materials related to synthetic biology.

IGEM Qdai 2020

This year is the first year that team Qdai is participating in iGEM. Our team consisted of members coming from different faculties such as Science, Agriculture and Engineering. Assembled in March of 2020, our journey started from finding team PIs. At the same time, we started our brainstorming. Because of the spread of COVID-19, all works were done online until October, when we were finally able to meet each other.
