Building AOPs is a collaborative effort. Experts regularly meet within working groups based on their interest and expertise. Once every 3-4 months, a CIAO workshop is organised to gather all experts together, share the results obtained so far and establish the future steps.


The 4rd online CIAO Design Workshop will take place on 15-16 September 2021.

Please contact us if you want to participate to the workshop or just have a look into the project.

50 scientists met  for 2 half-days to build an AOP network depicting COVID-19. You could find a Report of the Workshop soon here.

1-2 October 2020 - 1st online CIAO COVID-19 AOP Design Workshop. 

More than 40 international top scientific experts spent 2 half days to assemble first stable and agreed draft AOPs depicting COVID-19 pathogenesis.

Following that, and over a time period of 3 months, 5 working groups (see diagram) were busy with the further elaboration of COVID-19 AOP-related Key Events in these COVID-19 AOPs.
