My main research interest is in malaria epidemiology. Before re-joining the School in 2007, I worked for the Malaria Research Programme of the South African Medical Research Council. I was president of the South African Statistical Association in 2006/7.
I co-organise the Intensive Course in Epidemiology and Medical Statistics. I also teach on the study units Statistical Methods in Epidemiology, Epidemiology and Control of Malaria, and Extended Epidemiology.
My research focus is the evaluation of comprehensive malaria control interventions; cluster randomised trials evaluating vector control tools; the potential added benefit of combining malaria vector control interventions; the impact of insecticide resistance on the effectiveness of insecticide-based malaria vector control tools; the epidemiology of malaria elimination. I have been the senior epidemiologist of the Bioko Island Malaria Control Project since its inception in 2003.
