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 6 sessions with 30 speakers culminating in more than 720 minutes of solid intellectual fun!

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

Because of COVID-19, the organizing committee made the difficult decision to move our Global Gastronauts Symposium to on online virtual venue.

However, this change has brought the opportunity to connect even further with our global community of scientists working on gut-brain matters. The virtual event will include six stellar scientific sessions of two hours each. And each hosted live from one of six global locations: Adelaide – Australia, Doha – Qatar, Durham – USA, London – UK, Nantes – France, and Porto Alegre – Brazil. This event will take place May 11-13, 2021.

Please save the date!!!

Registration will open February 1, 2021
