- Research Associate (Systems Power & Energy)
Biography
Following the award of a Bachelor of Engineering (Aerospace, Honours) from the Mechanical Engineering Department of International Islamic University Malaysia, I joined Masdar Institute (now Khalifa University), Abu Dhabi, for an MSc in Mechanical Engineering. While working there as a Research Assistant, I explored robust numerical techniques and computational tools for predicting the behaviour and failure of materials and structures. This continued in Sheffield where I developed an adaptive isogeometric finite element framework for gradient elasticity and gradient plasticity resulting in a PhD from the University of Sheffield.
The computational techniques I have worked on have wide-ranging applications from the design of sustainable buildings to efficient extraction of the earth’s resources. For example, I have modelled fold-induced rock fractures and investigated advanced concepts to manage losses in conventional geothermal systems. After my PhD, I joined a carbon capture and storage joint project between Eindhoven University of Technology and Shell International BV to develop a coupled multi-physics hydraulic fracture simulator.
At the end of July 2021, I joined the University of Glasgow where I am working on two EPSRC net-zero projects: NetZeroGeoRDIE – looking at repurposing the Newcastle Helix Borehole as a deep coaxial borehole heat exchanger, and INTEGRATE – focusing on underground thermal energy storage in the UK.
