Our partners at I.U. in the Glazier Lab and Biocomplexity Institute have announced the 2025 CompuCell3D Virtual Tissue Modeling Workshop and Hackathon at Indiana University, Bloomington, July 28th to August 10th, 2025. Learn to model your biological system of interest with one-on-one help. Week 1 will cover CC3D basics. Week 2 will cover advanced topics in CC3D, followed by a 2-day model-building hackathon. Physicists, biologists, computer scientists, and modelers team up to build research-grade models of biological systems. All experience levels are welcome.
