I am a marine ecologist with a soft spot for parasites. My research revolves around understanding the ecological role of parasites in marine ecosystems on various spatial and organizational scales.

Using lab and field experimental approaches, my research group studies the effects of parasites on marine host individuals, populations and communities. We are also interested in how parasites influence the topology and dynamics of food webs. Another line of research aims to understand the patterns and processes underlying infections of marine hosts. This includes work on the role of ambient biodiversity in affecting parasite transmission and disease risk as well as studies on the effects of global changes such as rising temperatures and biological invasions on marine parasites and their hosts. Finally, we study large-scale patterns of parasitism using literature-based datasets and biogeographical and macroecologial approaches in order to understand the forces that have shaped parasitism in the sea.
