Research interests
- Statistical methodology for high-dimensional data (e.g. gene expression profiles)
- Quality assessment and improvement for high-dimensional data (e.g. microarrays, X-ray detectors, additive layer manufacturing)
- Spatial modelling (e.g. microscopic images, colocalisation of proteins, dead pixels)
- Modeling decision-making processes involving complex information (cancer recurrence risk, biographic profiles)
- Intuitive versus normative concepts of probability, risk and uncertainty and implications on decision making (e.g. in behaviour finance)
Supervision
I have supervised supervised 31 Master level projects (MMORSE, MMathStat, Masters in Statistics, Masters in Epidemiology) at Warwick and Queen's University and am currently supervising 2 such projects. 3 of my PhD students have graduated in the last two years and I am currently (co-)supervising 5 PhD projects.
Topics include methods for statistical analysis of high-dimensional data from genomics, spatial analysis using image data (e.g. X-ray, microscopy), medical statistics (e.g. cancer screening, predictors for survival, questions related to trial design), perception of randomness and behavioural decision theory (e.g. medical treatment decision, finance, admissions).
Students with an interest in a suitable topic of their choice, whether included in the list or not, are encouraged to contact me for this to be considered.
