Gastronauts Nantes 2021

To make us who we are, food must agree with the gut and the brain. This venue for scientific gut-brain dialogue is Gastronauts

When a behavioral neuroscientist sits with a synthetic biologist for breakfast, one can envision a witty probiotic designed to tame our cravings.

In Nantes, the table will be served with fine ideas carefully nourished in laboratories around the world. Guts in space, mind bending gut surgery, guts on a chip, and self-medicating chimps are just a few of the topics to be delivered by our carefully curated list of scientists.

We have 8 sessions with 30 speakers, and 3 discussion panels culminating in more than 1,800 minutes of solid intellectual fun!

Join us in Nantes, France, May 11-13, 2021.

In light of the COVID-19 pandemic, the Gastronauts Organizing Committee has decided to postpone Gastronauts Nantes to next year May 11-13, 2021. This enables our Gastronauts Community to stay safe and bounce back stronger than ever once the pandemic has passed.

Gastronauts is a venue that fosters diversity, values sharing our science openly, and strives to continue building a strong community. Those principles have brought us here and will continue to keep us moving forward. We hope that you will be able to join us in 2021.

Registration will open September 12, 2020

Registration fees are $245 for students, $445 for non-students, and $745 for industry. The registration deadline is March 12, 2021.
