I am a statistician in the Instititue of Applied Health Research. My research interests relate to experimental design, particularly cluster randomised trials, spatial statistics, and their intersection. Recent and ongoing grants I lead include an MRC/NIHR funded project examining the design and analysis of evaluations of interventions in space (and time), particularly focussing on generalised linear geospatial and mixed models; an NIHR/UKRI funded project on methods for real-time disease surveillance using geospatial prevalence mapping methods; and a small GCRF project piloting use of low-cost imperfect tests as outcome measures for prevalence estimation and evaluation of local interventions. 

I am also a co-investigator for several global health trials and survey-based projects including the NIHR Global Health Research Unit on Improving Health in Slums (NIHR), a stepped-wedge trial of integrating depression care into routine HIV and chronic illness services in Malawi (NIH), the NIHR RIGHT programme on leprosy and Buruli ulcer, and a stepped-wedge trial of remote telephone consulting in Tanzania and Nigeria (NIHR/GCRF).
