Mark is a medical statistician with a particular interest in statistical methodology for meta-analysis. His research interests include the meta-analysis of individual patient data, time-to-event data and of medical screening tests. He is also interested in preventive medicine and medical screening for cardiovascular and other diseases.

Mark has a PhD in medical statistics from the University of Cambridge, where he developed statistical methods for individual patient data meta-analysis. Since then he has been engaged in trial design and meta-analysis of pharmaceutical trials and has engaged in statistical research in preventive medicine, including meta-analyses in the prevention of dementia, and investigating the cost-effectiveness of methods of screening for future cardiovascular disease.
