The following Conference Session topics comprise the 40 oral and poster sessions that will take place from Monday to Thursday at the Conference. There will be five parallel oral sessions each morning and afternoon. Each session will be 2 hours long, with a combination of invited speakers and speakers selected from the abstracts submitted. Posters will be hung on the day of the relevant session and online all week as well as before the conference. For the program at a glance, click here.
