Macrophage & Dendritic cell biology

We are working to understand how phagocytosis is regulated; how phagosomal pH, membrane integrity, and maturation is normally controlled and subverted by bacteria; and how autophagy may impact on intracellular bacteria survival.

We use novel fluorescent sensors and advanced microscopy (in collaboration with Dr Steve Lee, Chemistry Cambridge), model organisms such as dictyostelium (c/w Dr Rob Kay, MRC-LMB), and functional assays to understand the cellular regulation and molecular effectors of phagosomal function.
