Cambridge Immunology Network



I am a structural and computational biologist with a background in EM, light microscopy, biophysics, and X-ray crystallography. I am interested in combining low resolution microscopy, biophysical, and biochemical methods (including FRET and crosslinking) with atomic modelling to understand protein and RNA assemblies involved in signalling, bacterial virulence, and innate immunity.

Working in Profs Clare Bryant and Nick Gay's lab I am looking at the trafficking and interactions of TLR receptors and their associated adaptors. 

I also have an interest in new ways to visualize and annotate data in combination with 3D structures.
