Legal work



I am Professor of Risk Information Management at Queen Mary University of London and a Director of Agena, a company that specialises in risk management for critical systems. I’m  a mathematician by training with current focus  on critical decision-making and, in particular, on quantifying uncertainty using causal, probabilistic models that combine data and knowledge (Bayesian networks).  The approach can be summarized as 'smart data rather than big data'.  Applications include law and forensics (I've been an expert witness in major criminal and civil cases), health, security, software reliability, transport safety and reliability, finance, and football prediction.
