Dr McLoughlin got her start in research in the field of evolutionary immunology. Her work on the interactions between the adaptive immune system and the microbiota has led to her expertise in the mathematical modelling of biological systems. Dr McLoughlin’s work now focuses on melanoma and ovarian cancer research, particularly on using models to assess the utility of screening in reducing the burden of these cancers. Her interests include evolutionary dynamics, how they can influence complex health systems, and how understanding these networks can allow us to improve population health.
