Jo Haviland


Reader in Medical Statistics



I am a statistician with extensive experience of working in academic medical research, particularly clinical trials. Following a BSc in mathematics and an MSc in medical statistics at the University of Southampton I worked at the MRC Sickle Cell Research Laboratories in Jamaica. I then spent five years at the London School of Hygiene and Tropical Medicine working on epidemiological studies and clinical trials, primarily focussing on HIV and TB in sub-Saharan Africa. At LSHTM I was involved with designing and delivering statistics and research methods modules for MSc programmes and with supporting PhD students, which sparked my long-standing interest in teaching applied methods to non-statisticians.

In 1996 I joined the Clinical Trials and Statistics Unit at The Institute of Cancer Research, furthering my interest and expertise in clinical trials from design and funding application through to analysis and reporting. I worked on a number of trials that have changed standard radiotherapy treatment for breast cancer in the UK and worldwide. At the University of Southampton, I have worked in the trials unit, NIHR Research Design Service, and the Macmillan Survivorship Research Group that investigates consequences of cancer and its treatment. Methodological interests include reporting of adverse effects, particularly from radiotherapy, and patient-reported outcomes.


I lead the statistics group in the Pragmatic Clinical Trials Unit within the Centre for Evaluation and Methods, continuing my interest in clinical trial methodology and conduct. I am a member of the Clinical Evaluation and Trials committee of the NIHR Health Technology Assessment funding programme, the UKCRC CTU Network Statistics Operations Group and am the independent statistician on a number of trial oversight committees for other trials units


Research Interests:

My main interest is in developing clinical trials that are efficient and deliverable, and which improve outcomes for the populations being studied. Methodological interests include statistical aspects of clinical trial design, reporting and analysis of adverse effects, and use of patient-reported outcomes.
