Dr Neil O'Leary

B.Sc.,M.Sc.,PhD

Biography

I joined the School of Mathematics and Statistical Sciences in 2023, having previously been at CORRIB Research Centre for Advanced Imaging and Core Laboratory and the HRB-Clinical Research Facility Galway since 2016.

I am an applied statistician with a wide range of methodological interests; in particular the design and analysis of clinical trials, multilevel modelling of clustered and longitudinal data, along with other applied research interests in causal inference in observational studies, survey techniques and missing data.

I am experienced in the analysis of complex longitudinal observational studies. I am well-versed in best practice for clinical trial design, data monitoring, data preparation and analysis; drafting standard operating procedures, protocols and statistical analysis plans and reports. I have experience of trials in the regulatory environment relating to medical devices and also behavioural and mental health interventions and cluster randomised trials, and I have served as the lead statistician for a large national population study in ageing.
