Rotordynamics in general and the rotordynamics of machines with laminated rotors in particular. Robust balancing for high performance (high power density) rotors. Modelling the coupled dynamics of electro-mechanical systems - electrical machines in particular. Monochromatic power transmission taking advantage of some fundamental properties of certain two-degree of freedom dynamic systems.
Also an area of mathematics called "Structure Preserving Transformations" and recently I have developed a strong interest in "Integrated Compressed Air Energy Solutions" whereby renewable sources (wind/wave/tidal) are used to compress air directly and this is subsequently expanded for generation.
Vibration in large electrical machines: The electromagnetic dynamics of windings of large electrical machines: Control of multiple independent drives for high-performance machines: Composite system assembly (i.e. dynamic substructuring). High Specific Load Capacity Magnetic Bearings. Noise and Vibration in Electrical Machines.
Extending the application of the Structure Preserving Transformations to machine vibration control and towards final applications in matrix polynomial eigenvalue problems: Further development of the ICAES (compressed-air energy from renewables) ideas. Further work on balancing and on modelling complex electromechanical systems. Active clearance control in rotating machines:
