The more you talk about your ideas and listen to feedback of others, the better your research will be. It is most definitely good to talk! This is what academic conferences are for and indeed vivas for some master's courses and for PhDs. CRIS is managed by Anne who has more than a decade of postdoctoral research experience so don't forget to book a 15-minute appointment to discuss your ideas for collaboration!
