I completed my PhD in 2006 at UCL and worked for a year at Queen Mary University as a research fellow in the Wolfson Institute of Preventive Medicine.  I joined LSHTM in 2007 in the Faculty of Epidemiology and Population Health, and started my current role, attached to the Royal College of Surgeons, in February 2011. 


Department of Health Services Research and Policy
Faculty of Public Health and Policy


I am Deputy Module Organiser for Basic Statistics for Public Health and Policy. I also lecture and run practicals on and Advanced Statistical Methods in Epidemiology (ASME). I am a personal tutor for students doing the MSc in Public Health.


I am based in the Clinical Effectiveness Unit, a collaboration with the Royal College of Surgeons. My research includes developing risk models, statistical issues in performance monitoring, linkage of multiple routine datasets and developing clinical indicators from large routine datasets. The clinical area of my research is primarily the management and outcomes of patients with bowel cancer.  I am the lead methodologist for the National Bowel Cancer Audit and the National Non-Hodgkin Lymphoma Audit, and senior statistician for the National Cancer Audit Collaborating Centre, carrying out health services research using linked data from large clinical and administrative databases.
