The mini-colloquia are a central part of the scientific program of the OePG-CMD-Graz2026 conference. Highly focussed scientific topics were suggested from external scientists and confirmed by the program committee. The program of the individual mini-colloquia will be prepared by the organizers of the mini-colloquia by inviting speakers for an introduction of the scientific topic and by selection of short talks and of posters from the contributed abstracts.
