Scientific Program

Below is the tentative scientific program for GCMAS2021. We have chosen to keep the conference virtual due to an abundance of caution and as a consequence, we have shortened the conference from three and a half to two days. Although we have attempted to accommodate many of the interests we usually do, time is more limited so events which were previously an hour or more have been condensed. Exhibitors will have their own virtual rooms which we will link to, and will be available throughout the day. However, we are also providing certain prime time slots for exhibitors who wish do more extended presentations. The final program will be found on our conference presentation website which will go live 2-3 weeks prior to the conference and will be linked to through this site.
