Contact InformationResearch Interests
My research focuses on the structure and function of integral membrane proteins, with emphasis on inner membrane transporter proteins involved in sugar-phosphate uptake and drug efflux in prokaryotes such as Escherichia coli, and those involved in metal ion uptake in pathogenic spirochaete bacteria. I am also interested in the structures, mechanisms and membrane targeting processes of apicoplast membrane transporters from malaria-causing parasites of the genus Plasmodium.My laboratory utilises a comprehensive range of state-of-the-art techniques to answer important questions pertaining to the structure and mechanism of membrane transporter proteins. These include X-ray crystallography, isothermal titration calorimetry, fluorescence spectroscopy and transport assays of protein reconstituted into proteoliposomes.
