Background

  • 2009 - present: Australian Postdoctoral Fellow (APD), ACMM, University of Sydney
  • 2007 - 2009: Associate Researcher, Bulk Superconductivity Group, Department of Engineering, University of Cambridge
  • 2006 - 2007: Research Fellow, Institute for Superconducting and Electronic Materials, University of Wollongong
  • 2000 - 2003: Teaching Fellow, Department of Science and Mathematics, Universiti Tenaga Nasional

Research project
Dr Wai Kong Yeoh is working with Dr Rongkun Zheng on the ‘Microscopic Origin of the Enhanced Flux Pinning in Nano-Doped MgB2 Superconductors’. This project aims to understand the microscopic origin of the critical current enhancement by nano chemical doping that will deepen the understanding of flux pinning mechanisms for practical MgB2 superconductor applications.

Other Research Interests

  • Superconductor’s flux pinning properties

    Structure- properties of relationships of superconductors
  • Melt-textured techniques
