Biography

I graduated with a degree in Mathematics and Economics. This was followed by a PGCE and an MSc in Medical Statistics and Information Technology. My PhD involved using computer intensive statistical methods for estimating sample sizes and analysing quality of life outcomes. I joined ScHARR in January 1995. I was promoted to Senior Lecturer in 2003; Reader in 2008 and to a Personal Chair in 2009. I was appointed Director of the Design, Trials and Statistics section in ScHARR in August 2012.

I am a Chartered Statistician with over 22 years’ experience of health services research and technology assessment. The main focus of my research has been in the design, analysis and reporting of trials of complex interventions; and the design, assessment, analysis and interpretation of patient reported outcomes in clinical trials. I work with clinicians from a variety of backgrounds to develop pragmatic clinical trial designs to capture the effectiveness and cost-effectiveness of a variety of health technologies. I have been co-investigator for more than 15 RCTs of non-pharmaceutical interventions.

 I have co-authored over 270 publications (including 161 in refereed journals and 4 books, with over 21,000 copies sold). The majority of my  peer-reviewed journal articles have been applied research, with the emphasis on the evaluation of new services. I have been a co-applicant, statistical advisor and collaborator on over 50 health services research projects.

Teaching Interests

I have developed several courses on teaching medical statistics to medical and health science students, clinicians and allied health professionals. I have also co-authored three textbooks: 'Medical Statistics: A Textbook for the Health Sciences' ; 'How to Display Data' and 'How to Design, Analyse and Report Cluster Randomised Trials in Medicine and Health Related Research'.

I co-ordinate and teach on HAR6035 `An Introduction to Statistics and Critical Appraisal´ module on the Master of Public Health programme and contribute to the distance learning version (HAR6042). I also teach on several other courses including: HAR674 Randomised Controlled Trials; MAS6061 Epidemiology; MAS6062 Further Clinical Trials.
