Recurring activities


Annual cycle of activities



Annually, the ctDNA Center extends an invitation to the Annual Meeting, consistently held in the third week of November. The primary objective of this gathering is to provide an update on the center's research, activities, and projects, fostering the reinforcement of current collaborations and the establishment of new ones. This event serves as an excellent opportunity to network with professionals in the ctDNA field. The meeting is primarily for center members, creating an ideal environment for sharing ideas and insghts, encouraging fruitful discussions and feedback.
