After completing a DPhil and postdoctoral period at Oxford, David started his own research group at The Natural History Museum, London (NHM), working on microbial evolution and ecology, particularly eukaryotes. He currently holds a joint position at NHM (20%) and Cefas (80%). His areas of expertise are molecular phylogenetics, molecular diversity studies (including environmental DNA (eDNA) sequencing and analysis), molecular taxonomy and diagnostics, and protistan biodiversity and parasitology. Current work focuses on applying molecular assays for a wide range of parasite lineages to understand their pathology, evolution, and ecology, understanding how microbial communities (e.g. microbiomes) contribute to health status of their host organisms and the health status of the surrounding environment, molecular early warning indicators for disease risk, emerging diseases, and ‘ground-truthing’ molecular/environmental signal from pathogens with actual infection of other organisms within that system, disease, and risk. He is President of Protistology-UK, the professional society of protistologists in the UK, and on the Advisory Council of UniEuk, a large initiative to resolve the taxonomy of micro-eukaryotes and provide robust sequence and taxonomic data to the wider community.
