Protozoan parasites cause many of the world's worst diseases and are amongst the greatest sources of suffering and death. Because most are restricted to the developing world, researching the biology of these organisms with a view to deriving effective drugs, vaccines and diagnostics has been long neglected. My research has been focussed on this group of organisms for many years and my group's research investigates the interactions between these organisms and their human host, and whether by elucidating and disrupting these interactions we can provide novel therapies.
In the fight against disease, I believe it is important that tomorrow's doctors are able to incorporate understanding and indeed practice of biomedical research into their treatment of disease; to understand the importance of the evidence base for the practice of modern medicine. For this reason at UEA I have worked to introduce a research project into the MBBS syllabus and an intercalated MRes course for those medical students wishing to pursue research actively during their medical careers. I hope to be able to offer an intercalated PhD course to medical students in the future.

Key Research Interests
We are investigating the way in which Trypanosoma cruzi is able to manipulate host cardiomyoctes to facilitate invasion and for intercellular survival. Our approach is primarily by real-time fluorescence microscopy of host/fluorescent protein chimaeras and fluorescent probes and by use of molecular and chemical intervention.
Trypanosome Cell Biology
We are investigating the requirements and mechanism of cytological change in trypanosomes; in particular, the roles of cytoskeleton and membrane rafts.
We are investigating the evolution of parasite molecules which are associated with host specificity and virulence in a number of parasites.

I am interested in working to ensure that clinicians are able to understand the scope and limitations of scientific research and are able to integrate research into their clinical careers. To this end I have manage provision of the short research project of the MB/BS and the intercalated MRes degree (the first of its kind in the UK). In the near future I hope to be able to offer some students the opportunity to pursue a seven year fully integrated MB/PhD program which at this time will be unique in the UK.
