iGEM IONIS is the IONIS team attending to iGEM competition in Paris, a prestigious synthetic biology contest that gathers more than 300 teams from the entire world. Our team is composed of students from schools throughout the whole IONIS group, the biggest private French education network, that benefits from various domains of expertise, from applied sciences and biotechnologies to communication and design. During the 2022 iGEM competition, our team won a Gold Medal and the price of the best Climate Crisis project. This year, we decided to attend the competition with the project Clean Heat: a heating and water depolluting bio-based system.
