The 14th annual international European Crystal Network was held in Paris on 2 and 3 March 2023. This in-person meeting was attended by 93 participants. Over 40 research abstract submissions were received from investigators, ranging from early career investigators to senior researchers, for plenary oral and poster presentations. Here, we present the accepted, lightly edited abstracts from the presenters consenting to have their work published. We thank and congratulate the presenters for their work and contributions to the meeting.
