G2NET is a four-year project (2018 – 2022 ) supported by COST Action CA17137. It is based on the participation of 26 COST countries. The main aim of this Action is to develop advanced techniques for detection of gravitational waves, drawing from expertise in physics, mathematics, information science and computing. MISANU is actively contributing to G2NET and takes a leading role in one of the working groups, actively supporting young scientists, as well as the diversity and regional developments in the field.
