Professor Stephen Evans BA MSc FRCP (Edin) 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 generally act as a 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 and the MSc in Medical Statistics.


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.
