Alastair graduated from the University of Exeter with a First Class MMath Degree in 2014. During this time, he undertook placements within the University of Reading Meteorology department and the Met Office in conjunction with his Masters project. He submitted his PhD in Applied Mathematics from Imperial College London, under the supervision of Dr. Colin Cotter, in December 2017, and was awarded it in June 2018. This was entitled: 'Multilevel Ensemble Data Assimilation'. Alastair also worked as a Research Assistant at Imperial College London studying the feasibility of applying a novel variance reduction technique to flood risk assessment. A highlight of his work as a postgraduate researcher at Imperial College London was being awarded the Doris Chen Award in 2017.
Alastair is now working as a Statistics Research Associate for Imperial College London, based at the Alan Turing Institute (ATI). The work is part of the Data Centric Engineering Programme (https://www.turing.ac.uk/research_projects/programme-data-centric-engineering) at the ATI. In particular, Alastair is working with Dr. Din Houn-Lau and Prof. Mark Girolami in using an abundance of sensor data from infrastructure, such as network railway bridges, to improve the maintenance and productivity of them.
