Biography

Dr Hindolo George-Williams graduated with a dual PhD in Risk & Uncertainty Engineering from the University of Liverpool and Nuclear Engineering from the National Tsing Hua University in 2018. In his research, he developed an efficient computational framework for the reliability, maintenance, and performance modelling of complex systems, with a view to initiating a paradigm change in the probabilistic risk assessment of nuclear power plants, as well as the performance evaluation of other power systems.

Until his move to the University of Oxford, Hindolo was a Power Systems Research Engineer in Newcastle University’s Electrical Power Research Group, working on a demonstrator project for smart grid-integrated electric vehicle charging renewable energy infrastructure. Previously, he was the country lead of Total Sierra Leone’s maintenance team, overseeing proceedings across 30-40 fuel service stations and sites. He joined the Energy and Power Group in November 2019 to work on a project seeking to improve the electricity supply of his native Sierra Leone via a whole systems approach.

Research Interests

Hindolo is interested in developing revolutionary probabilistic frameworks for the reliability, risk, maintenance, and performance assessment/improvement of complex systems with a bias for power systems. Some of the frameworks he has developed in the past have been applied to a series of case studies ranging from the availability assessment of an offshore oil installation, the maintenance strategy optimisation conundrum of a complex power distribution network, to the probabilistic assessment of station black out risks at a Pressurised Water Reactor nuclear power plant in Taiwan.

He has also done extensive work in distributed energy systems, with keen emphasis on their optimal design, energy management strategies, and techno-economic assessment, as well as vehicle-to-grid integration. In his work at Newcastle University for instance, Hindolo developed a novel software for the techno-economic assessment (in the presence of uncertainties) of grid-integrated solar carports for bidirectional electric vehicle charging, in collaboration with Innovate UK and Flexisolar Limited.

Current Projects

Hindolo works as part of a team of academics looking at improving Sierra Leone's electricity supply. This is part of the UK Department for International Development (DFID) funded Energy and Economic Growth (EEG) applied research programme.
