Working on a proposal with a global reach

I am currently collaborating on an ERC proposal with Professor Kazunari Domen from the University of Tokyo, Professor Arne Thomas from TU Berlin, and Professor Shannon Boettcher from UC Berkeley. It's fascinating to work alongside such world-renowned researchers whom I previously knew only from research papers. However, it feels like the SEPL would need to put more effort into its outputs to partner with such high-level academics.
