2021-6-24 CCAM’s annual Computational Cell Biology Workshop was again held online June 21-23, 2021. The workshop provided instruction to over 50 individuals from around the world on mathematical modeling techniques using VCell, COPASI and SpringSaLaD software. Fifteen of the participants worked closely with CCAM researchers to develop their own models related to their research projects. Another successful year for the modeling workshop! a combined workshop for VCell, COPASI, and SpringSaLaD modeling software. Thanks to all for a very successful course! Videos of the classes and presentations can be found on the CompCellBiol YouTube channel.
