Energy Transitions Research at the University of Cambridge



Dr Mark Ainslie is a Research Fellow in the Bulk Superconductivity Group, part of Division C (Mechanics, Materials and Design) of the Department of Engineering. He is also a Junior Research Fellow at King's College. His research interests are in applied superconductivity in electrical engineering, including superconducting electric machine design, power system protection and energy storage, and electromagnetic modelling, including FEM.

He is currently funded by the Royal Academy of Engineering and is working on engineering interactions of conventional, magnetic and superconducting materials for electrical applications. This project is focused in particular on the design of an axial gap, trapped flux-type superconducting electrical machine.


Applied superconductivity in electrical engineering, including:

  • Superconducting electric machine design;
  • Power system protection;
  • Energy storage; and
  • Electromagnetic modelling, including FEM.
