Professor Stephen Evans BA MSc FRCP (Edin) FISPE Hon. FRCP (Lond)

Professor of Pharmacoepidemiology


My first degree was in physics and chemistry and included a year in the US doing physics and philosophy. Having worked in computing I did the MSc in Medical Statistics at LSHTM and worked in statistics and computing at The London Hospital and Medical College for 25 years. I have also been at the UK Medicines Control Agency and briefly at Quintiles where I mainly worked on the Bristol Royal Infirmary Inquiry. I am a European Commission appointed independent Expert member of the Pharmacovigilance (Drug Safety) and Risk Assessment Committee at the European Medicines Agency. I was President of the International Society of Pharmacoepidemiology for 2010/2011.  I am now semi-retired and do not act as sole supervisor of PhD students.




I helped start the short course in pharmacoepidemiology and pharmacovigilance and teach on that course and the Practical Pharmacoepidemiology short course. I also contribute to the DL MSc in Clinical Trials, the MSc in Medical Statistics and the Short Course on Vaccines.


Safety of medicines is my major interest. Assessment of safety and risk in a general sense, but particularly in trials and epidemiological studies, especially in electronic health records, are the main topics. I am also interested in scientific fraud and misconduct, especially in clinical trials.
