Prof Gary Abel
Senior Faculty
Gary is a senior lecturer and Statistician working in Primary Care research at the University of Exeter where he has been since early 2016. Prior to taking up his post in Exeter he worked as a statistician in the Primary Care Unit at the University of Cambridge. Before this he had a career as a researcher with the British Antarctic Survey studying the near Earth space environment.
As a statistician, Gary works across a broad range of health and healthcare areas but has a particular interest in the early diagnosis of cancer. His research has often focussed on the use of routinely collected data and he will be bringing this expertise to the CanTest programme. His previous research has brought the power of cancer registry data, primary and secondary care data, and patient experience data to bear on the examination of cancer diagnosis. In his role as lead statistician for CanTest he will provide methodological advice across the programme supporting the full range of activities.
