Network Investigator


Research Keywords: 

Melioidosis, Human Clinical Trials, Diabetes



I gained a PhD in malaria vaccines development at Jenner, Oxford and then after completing clinical specialist training in infectious diseases I moved to the Mahidol-Oxford Tropical Medicine Research Unit (MORU), Bangkok, Thailand in 2011 to establish my research group evaluating immune responses to Burkholderia pseudomallei and Orientia tsutsugamushi (scrub typhus) in human patient populations. Since 2015 I have also run the Tropical Immunology Group at Medawar, Oxford which is working on immune correlates of protection from death in acute melioidosis, and characterising the mechanisms of susceptibility of people with type 2 diabetes to intracellular pathogens. Techniques include ELIspot, flow cytometry, whole blood stimulation field assays, cellular bioenergetics analysis, metabolomics, transcriptomics, flow cytometry and functional growth inhibition assays. I have overseen establishing capacity in Dhaka, Bangladesh for enhanced laboratory microbiological diagnosis and immunology studies.
