Dr Stuart Johnston is a mathematical biologist who focuses on multiscale modelling of migration processes. He has experience in modelling cellular behaviour, as well as the motion of individuals and animals. He regularly connects his models with experimental data to generate new biological insight.

Dr Johnston has developed mathematical models of the interactions between nanoparticles and cells, to understand and design future medical treatment delivery options. In 2020, he commenced an ARC Discovery Early Career Research Award Fellowship to study the ability of organisms to navigate through environments in the presence of uncertainty and noise, with a focus on cell transport and whale migration. He is currently a Lecturer in Applied Mathematics in the School of Mathematics and Statistics.
