Ecological interactions and spatial dynamics in microbial aggregates: A novel modelling framework
Viktoria Freingruber, Rebeca Gonzalez-Cabaleiro, Havva Yoldaş
We present a mathematical model based on a system of partial differential equations (PDEs) with cross-diffusion and reaction terms to describe ecological interactions between multi…

Trait-structured chemotaxis: Exploring ligand-receptor dynamics and travelling wave properties in a Keller-Segel model
Viktoria Freingruber, Tommaso Lorenzi, Kevin J. Painter +1
A novel trait-structured Keller-Segel model that explores the dynamics of a migrating cell population guided by chemotaxis in response to an external ligand concentration is derive…

A biased random walk approach for modeling the collective chemotaxis of neural crest cells
Viktoria Freingruber, Kevin J. Painter, Mariya Ptashnyk +1
Collective cell migration is a multicellular phenomenon that arises in various biological contexts, including cancer and embryo development. "Collectiveness" can be promoted by cel…
