Yes. The presenting author of an abstract must have a paid and confirmed registration for the conference to be finally approved for presentation and be included in the program. However, you must register either before the submission or immediately after being informed of approval for your submission to be valid and your presentation to be included in the program. We recommend submitting your abstract as early as possible. We will review the abstract and inform you within 10 days after the submission so that you can register for the conference early and benefit from the discounted fees.
