David holds a Master of Science in Epidemiology from the London School of Hygiene and Tropical Medicine and a PhD from the University of Amsterdam. Since joining KWTRP in August 2008, his research work has spanned a range of disciplines including, clinical trials, evaluation of quality of care within hospitals and exploration of the application of various statistical methods (propensity score analysis, multi-level models and statistical process control) to routine data. David played a key role in development, database design and setting up the Clinical Information Network - a pragmatic research database collecting patient level data from all paediatric admissions from 14 county referral hospitals and aims at improving use of information in policy and practice. He has broad interests’ in the use of epidemiology to monitor disease trends, interventions effects, identify quality of care gaps and the use of this data for effective decision making although with a bias on how human resources for health more specifically the nursing workforce influences the quality of care provided. His future work aims at developing human resource interventions as well as optimising approaches for nursing care provision.
