Principal Research Interests

My research focuses on the cell biology of the T-cell immune response, particularly the genes and signalling pathways that T-cells use for migration and activation.

I have used several functional approaches to elucidate these pathways, including RNA interference (RNAi), screening of RNAi libaries and High Content Image Analysis.

The translational aspect of my research aims to understand how these pathways may be manipulated for the treatment of autoimmune/inflammatory diseases, infectious diseases and cancer (immunotherapy).
