Differentiable Optimization for Cancer Modeling

Technologies: Julia, Cellular Potts Model (CPM), Stochastic Derivatives

Code availability: Open-source (Julia package)

Description: This research addresses the challenge of parameter optimization in stochastic lattice models — specifically the Cellular Potts Model (CPM), a widely used tool in cancer biology. CPM simulates the behavior of cells within tissues using probabilistic rules on a grid-based lattice.

My Role: Developed a novel gradient-based framework using automatic differentiation for discrete, stochastic models. The method overcomes the long-standing challenge of CPM’s non-differentiability. I applied it to prevent fingering instability — a phenomenon linked to cancer metastasis — by optimizing the model to suppress the formation of invasive cell structures.

This work lays the foundation for scalable, generalizable CPM simulations and enables the use of optimization techniques in previously inaccessible biological modeling domains.
