I presented an overview at the 2nd workshop of German Science Opportunities for the ngVLA, about classification of radio sources related to galaxies in radio surveys, and science related techniques/tools (experts, citizen scientists, ML/AI) we can apply for the future. Highlights featured my work on the COSMOS field, and our efforts to build the citizen science project ‘RGZ-EMU’. I feel very honoured to have attended this fantastic meeting full of science and discussions about the future of radio astronomy!
