My principal research is in the design, characterization and use of power semiconductor devices. My current research in this area focuses on the use of high voltage IGBTs connected in series, the characterization of IGBTs and the computer modeling and optimization of IGBTs and diodes. I also have an active interest in the computer simulation of multi-disciplinary systems, including power electronic circuits for hybrid electric cars, optimization of ship propulsion and captive power systems and fuel cells. An interest in energy saving in digital circuits resulted in the world’s fastest switch mode converter operating at 4GHz, fabricated in a 90nm silicon process.

I am currently Reader (equivalent to Associate Professor) in Electrical and Electronic Engineering at the Department of Engineering, University of Cambridge. I joined the teaching staff of the Department of Engineering in 1985, after completing my PhD. I also spent three years as Associate Professor at the University of British Columbia, Canada. I was also visiting professor at the University of South Carolina, Columbia, SC, USA. I have 30 years research experience in the design, characterization and use of power semiconductor devices and their circuits. I am a cofounder of Amantys Ltd, a Cambridge start up company, which has raised around £10m in funding and contracts.
