Modeling aspects are playing an increasingly important role in many sciences. Therefore, TRA Modelling organizes a network event to bring together scientists across disciplines. The event is 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, we explicitly invite senior and junior scientists without membership in TRA Modelling to attend if they feel addressed by the topics (see program below).  

The event offers five parallel sessions, each dealing with a topic that is a promising area of application for modeling approaches. The parallel sessions are chaired by experienced  TRA scientists who conduct research related to those topics. If you would like to contribute to the existing sessions and present something yourself, you are invited to submit a short abstract by March 19 (max. 1 page). The responsible session chairs will decide on the inclusion of your contribution into the program. The goal of the event is to exchange about project ideas and new research initiatives at an early stage. Therefore, please also state your motivation for presenting something in your abstract. 

To be able to plan ahead, all participants have to register! Please note that we have a limited number of seats available and an early registration is highly recommended. Please select a parallel session during the registration process, regardless of whether you would like to submit an abstract or simply attend a sessions as a participant. Abstract can be submitted during the registration process (alternatively you can send a mail separately once registered).

We are looking forward to welcome you to the TRA networking event 2025!
