Research areas

My research interests are special electrical machines, novel topologies of permanent magnet machines, computer-aided design of electrical machines, finite element methods, optimisation methodologies, cooling design and analysis, renewable energy systems. Recently, my work has been focusing on magnetic gear and magnetically geared electrical machine technologies. Our research has been mainly supported by local and international companies.
