Academic-Administrative Work


Research Interests

My main area of interests are renewable energy, design of electric machines, and power electronics. In particular, I am working on novel drive-train concepts for wind energy such as high-temperature superconducting machines and direct-drive generators. I am also interested in modular and fault-tolerant electrical machines.
