27-29 May 2026 
Paris, France

This is the official registration page for conference participants. Please note that the attendance fee of 124 euros is required. You have the option of adding the Friday night dinner cruise on the Seine river (36 euro fee). If you wish you join one of the guided tours of two Parisian research institutions on Saturday afternoon, this is also the place to sign up for that. Both groups will go to the same institutions, just in a different order.

Please note that your invoice will be automatically generated and sent by e-mail once your purchase is complete.

Towards the end of the transaction, an optional cancellation insurance will be offered. This is not required and is offered through our ticketing agent Weezevent. If this option interests you, we encourage you to read the terms and conditions as this is operated independently from the conference. Thank you for your understanding.

If you have any questions or encounter problems during the purchase process, please e-mail us at : ydys2026@sciencesconf.org

We are excited to see you in Paris!
