Why they attended our past London editions

Thank you Gaël DUEZ for hosting a fantastic conference. I loved participating and as a speaker I was grateful for the warm welcome from the audience. Additionally, I was able to make hugely valuable connections, which will no doubt be helpful to to meet our ambitious Carbon Zero targets at Cambridge University Press & Assessment. Can't wait for next year!!

Julie Dennis, CTO (Cambridge University Press & Assessment)
