Personal profile

Research interests

My research is focussed on Bayesian stochastic modelling and inference across the interface of statistics, epidemiology, actuarial mathematics and life sciences. I have an interdisciplinary research record, with involvement in cross-sectional projects concerning statistical modelling in areas including critical illness insurance, epidemiological resilience to disease outbreaks and flood risk. My work also involves collaborations with researchers in life and biomedical sciences. I have supervised a number of PhD students to completion and I currently supervise PhD candidates in topics including Bayesian model assessment in epidemiology, chronic disease and mortality. Further research study opportunities are described on my personal webpage.


I hold an Associate Professor position at Heriot-Watt University. Previous posts include a lectureship at HWU (2004-2012) and post-doctoral positions at BioSS and HWU (2001-2004). I am member of the Board of Examiners for the Institute and Faculty of Actuaries in the UK, and external examiner for a number of institutes in the UK and overseas. Professional memberships: Fellow of the Royal Statistical Society; member of the International Society for Bayesian Analysis; member of the Greek Statistical Institute. Education: PhD in Statistics (Edinburgh U); MSc (with Distinction) in Statistics and OR (Essex U); Ptychion (BSc) in Statistics and Actuarial Science (Piraeus U, Greece).
