TRA networking event 2025
Report:
Modeling aspects are playing an increasingly important role in many sciences. Therefore, TRA Modelling organized a network event bringing together scientists across disciplines. The event was open to all scientists who develop or apply modeling approaches to shed light on the function of complex systems. In addition to the experienced scientists who are already part of TRA Modelling, senior and junior scientists without membership in TRA Modelling were explicitly invited to attend if they felt addressed by the topics (see program below).
The event offered five parallel sessions, each dealing with a topic that is a promising area of application for modeling approaches. The parallel sessions were chaired by experienced TRA scientists who conduct research related to those topics. Further contributions had been selected by the responsible session chairs. The goal of the event was to exchange about project ideas and new research initiatives at an early stage.
We thank all participants for the high interest and the lively discussions at the TRA networking event 2025!
