I am Professor of Clinical Trials and the Director of the Swansea Trials Unit which I joined in December 2015. I have a varied educational background with a first degree in Social Sciences & Administration from Goldsmiths' College, University of London, an MSc in Information Systems Engineering from South Bank University, London and a PhD in Epidemiology from Tulane University, New Orleans. Previous employers have included the London School of Hygiene and Tropical Medicine, the UK MRC's Laboratories in The Gambia, the Louisiana Office of Public Health and most recently, the Wellcome Trust funded major overseas programme at the Kenya Medical Research Institute in Kilifi, Kenya. For this last post I was the Head of Statistics and held an appointment with Oxford University's Centre for Tropical Medicine. I have worked on trials and studies looking at malaria, malnutrition, HIV and respiratory diseases, amongst other things, mostly with an emphasis on children.

At Swansea my main focus is on expanding the Trials Unit with research concentrations primarily built around pre-hospital care, diabetes in conjunction with the Diabetes Research Unit, Cymru and surgical interventions. I am keen to establish a strong informatics setup for the Trials Unit and integrate with other Swansea based groups who have interests and expertise in this to foster methodological enhancements especially around the areas of E-Trials and patient reported outcomes.

  • PM-304 Biomolecular Research Project


  • PM-344 Capstone Project

    The aim of this module is to provide a capstone experience to students┬┐ learning, through participating in their own enquiry-based research project. Depending on the student's employability strand within the programme, the project may be laboratory, data, or education-based, but it will always involve a research question that is drawn from the literature, focused on a topic relevant to medical science. It will ask a novel research question and involve the critical analysis of research findings. Students will refine their oral and written communication skills to a graduate level through creating an introductory presentation on the project background, and a written dissertation and oral presentation on their research conclusions.
