Dr Bannon’s research expertise lies in applying novel statistical methods to understand variation in cancer patient survival. Modifiable causes include delays in diagnosis and treatment, and suboptimal treatment. These realities vary across sub-groups of the population defined—for instances—by age and the socio-economic deprivation. Population-based cancer registry data can measure population survival variation and explore its causes. Dr Bannon’s research aims to provide better statistical evidence to support change in cancer care services that improves, and reduces inequities in, cancer patient outcomes.
