The paper shows that varying interaction ranges between chasers and runners in heterogeneous populations leads to emergent chase-and-run dynamics at the population level.

The paper studies radially-symmetric anisotropic diffusion to model aggregation phenomena in biological systems without relying on chemotaxis or adhesion.

This paper derives non-local models of cell-cell adhesion and chemotaxis from a space-jump process and validates them with random walk simulations.
