The Bewick lab is looking to hire. If you're interested in insects, microbes, math, or a combination of all three, contact me at We are looking at all levels, from undergraduates to graduate students and postdocs!

 Research Interests

I am interested in population and community dynamics, particularly how detailed species life-histories can alter survival outcomes and how this is likely to interact with perturbations, for example global change, to impact species persistence. My favourite systems involve a combination of non-linear dynamics and insects - especially ants. However, I have studied a broad range of different organisms, from mosquitos, moths and butterflies to squirrels and trees. Recently, I've even been looking at the biodiversity of microbes on the human skin. Our goal is to extend current models of spatial ecology to consider patterns and processes driving the spatial distributions of bacteria, viruses and fungi on our bodies.
