Registration fees

CEST2021 will run as a hybrid event combining physical and virtual sessions


The registration process will be simple this year, considering the difficulties faced by most researchers and academics worldwide. Thus, you have now the opportunity to confirm your participation and include your paper in the program and the proceedings simply by paying the fees for the virtual event. If you eventually travel to Athens and join the event, you will need to pay the extra fee no later than the 20th of August.

We will keep reduced fees (early-bird prices for registration) throughout the entire registration period. However, you are advised to complete your registration as soon as possible to confirm your participation to the conference and include your paper in the conference program.

The participants who have already paid registration fees and will not travel to Athens due to COVID-19 restrictions, will be entitled to claim the difference between the physical and virtual registration fees a week after the conference.
