I am an ecologist interested in host-pathogen communities. My research combines field studies with molecular tools and ecological modelling. Currently, I study how the introduction of a virus vector affects disease transmission in bee communities.
Pollinator health declines and associated drivers such as pathogens have sparked concerns about declining biodiversity and threats to food security. Many pathogens that affect bee communities are multi-host RNA viruses. In honey bees, the global spread of a parasitic mite that vectors viruses has driven the emergence of a viral epidemic. As honey bees share floral resources with other species, such as bumble bees, flowers can mediate viral transmission and facilitate viral spill-over from honey bees into wild bee communities. I study how a novel transmission route through a vector affects virus epidemiology and evolution by comparing island bee communities that have been invaded by the mite with communities that are free of this vector.
I did my PhD with Phil Lester at Victoria University of Wellington where I studied the effect of invasive Argentine ants on viral disease in honey bees. I have a B.Sc. and M.Sc. from the University of Münster. My Master's research, which I did in collaboration with Victoria University focused on the effect of genetic diversity on fitness in invasive wasps.
