Dikai now holds a UKRI Future Leaders Fellowship in the development of novel light Mg alloys for next generation electric cars. His current research interests focus on developing high performance light alloys (e.g., Mg, Al, Ti), composites, and novel characterisation methods for several industrial sectors where light weighting and energy efficiency are urgently required.
Before taking up his fellowship, he completed his PhD at the University of Sheffield in 2015 and started a postdoc career in Sheffield from 2015 with Professor Mark Rainforth. In 2019, he joined the Henry Royce Institute @Sheffield and was the lead user of using the JSM-7900F SEM/EBSD/EDX and another JXA-8530F Electron Probe Microanalyzer (EPMA).

- Research interests
My research interests are to develop novel high performance light alloys (e.g., Mg, Al, Ti) and novel characterisation methods for several industrial sectors where light weighting is urgently required.
- Design alloys containing low-cost alloying elements only with high potential of high performance, reducing reliance on strategic metals and minimising waste in metal production.
- Develop 2-3 novel less-challenging severe plastic deformation (SPD) techniques integrated with multi-scale materials modelling to reduce grain size of light alloys
- Design simple section methods to acquire large volume of 3D microstructure information.
