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.
