Profile

Dr Dawn Walker is a senior lecturer in the Computational Biology Group in the Department of Computer Science. Her primary research interest is the use of individual-based models to understand the function and structure of biological tissues.

She is also interested in multi-scale and multi-paradigm models in biology and medicine, and the use of bioelectric properties of epithelial tissues in early cancer diagnosis.

Research interests
  • Agent (individual) based Modelling in predicting emergent properties of biological tissues
  • Multiscale Modelling in biological and biomedical applications
  • Electrical Impedance Spectroscopy (EIS) for the diagnosis of early cancerous changes in epithelial tissues
