I study the interactions of microorganisms with their environment, each other, and host organisms. This includes the study of parasites and symbionts, and their interactions with anthropogenic actions such as agrochemical exposure and climate change.

Much of my research is focused on the parasites and wider microbial community (microbiome) that live within, and transmit between, different bee species.
Working with governing bodies (Natural England), conservation bodies (Bumblebee Conservation Trust) and industry leaders (Biobest), my research has been influential in improving managed bee rearing practices and wild bee health.
These findings on managed bumblebees and parasite transmission have informed both conservation and policy, prompting recognition by NERC in their inaugural impact awards.
Recent research has demonstrated that flowers can act as transmission hubs for microbes between bee species, which has become foundational to several research strands; including, research into how being choosy about the flowers they visit may influence the risk of a bee catching a particular disease.
