Physics of Life are committed to supporting Early Career Researchers (MSc, PhD students and postdoctoral researchers). One way in which the network supports ECRs is through the delivery of Summer Schools. PoLNet2 delivered two summer schools in 2018 and 2019, each consisting of a week long intensive scientific programme with a diverse range of invited speakers. Activities also included networking opportunities, poster, and career development sessions (and of course, lots of social fun)! Each Summer school place was heavily subsidised by the network and highly popular. PoLNet3 will continue delivering Summer Schools equal in fun!
