The MAGPIE research group studies the dynamics of diverse interacting pathogens.We are building novel approaches to analyze and compare phylogenetic trees derived from sequence data, studying tree space and branching processes, and developing ecological and epidemiological models.

We also support public health with pandemic modelling alongside our own research. Our work involves case-forecasting, vaccination parameter estimation, genomic epidemiology and other topics in relation to COVID-19.
