The 2020 ASM was held online from 20th – 24th July. An outline of the programme is featured below. The programme also included several discussion groups. If you have any queries, please contact

Posters from the ASM: view and submit questions

Engagement and dialogue was encouraged for the posters associated with the ASM. The afternoon of Thursday 23rd July was dedicated to presenting the posters, with a Q&A at the end of each session. You can still view and submit questions about the posters. Please contact to obtain the password. You can then access the posters here.
