Projects per year
My research involves the creation and evaluation of models to support risk-informed decisions taken under uncertainty, particularly for decisions related to the introduction of innovative technologies and engineering systems within socio-technical contexts. I am a Chartered Statistician and a Fellow of the UK Safety and Reliability Society.
My research output includes novel methodologies created in response to challenging operational decision problems arising in different domains, including Maritime, Energy, Aerospace, Defence, Manufacturing and Financial Services. The methodologies developed encompass stochastic models, statistical methods and elicitation processes for problem and model structuring as well as probability assessment of model parameters. The projects underpinning my research – both basic and applied – have been funded by UK research agencies (EPSRC, NERC), the European Commission (H2020), the Royal Society, Innovate UK and industrial sponsors.
I am committed to making an impact through my research and knowledge exchange. I received a 1906 Award from the International Electrotechnical Commission in recognition of exceptional achievement and contribution to standardisation for dependability methods. I have successfully engaged in multiple industry-driven projects (including Knowledge Transfer Partnerships), outreach events and consultancies for a range of organisations. I have created and delivered educational learning material for post-experience, post-graduate and undergraduate programmes on topics including management science, stochastic processes, risk analysis, statistical modelling, decision analysis and operational research.
