Research interests

My research focuses on how macrophages form phenotypically and metabolically distinct granulomas via an 'epithelioid' differentiation stage. I am investigating differences between 'sterile' granulomas such as those seen in sarcoidosis and those induced by infection with the parasitic fluke Schistosoma mansoni. I am also interested in discovering granuloma-inducing pathways and means of inhibiting them through pharmaceutics.

Techniques, methods & infrastructure

In vivo and ex vivo work with transgenic mouse models including surgical procedures. Cell culture, activation assays, cell aggregation assays and visual analysis pipelines, multicolor flow cytometry, immunofluorescence.
