+The development of research software and the handling of research data has been essential for many areas within the fields of the [GAMM](https://www.gamm.org/en/) for decades and ranges from simulation scripts and data to accompany publications to extensive software libraries and petabytes of data for specific application areas.
+
+The GAMM Activity Group on Research Software Engineering and Research Data Management in Mathematics & Mechanics (GAMM FA RSE&RDM) aims at making a contribution here by providing impetus from the perspective of computer-driven sciences. They want to give the GAMM activities in the areas of research data and research software a visible home and promote synergies in the scientific exchange between the activities groups and identify GAMM-specific infrastructure requirements and fields of action.
