Session 2: Presentations from early career researchers & Virtual 'get-to-know-you'

This session consisted of two parts. First, there was a 90-min live online session with a series of brief presentations from early career researchers and Q&A, chaired by Anna ChaimaniCatrin Tudur Smith and Mark Simmonds (SMG Co-convenors).
