Professor Gehan Amaratunga FREng

Subject Engineering
Fellow type Lecturers, Professors and College Officers
Year started 1987


The big problem in getting more electric vehicles on the road is the size and weight of the batteries. The search is on for a different kind of capacitator to replace batteries, a fabricated nanomaterial that can efficiently store electrical power. This is Gehan's present goal. His field is power electronic devices and integrated circuits. He has a good few patents to his name and a clutch of spin-out companies. CamSemi won the 2009 University Spin-Out of the Year award. Gehan's work on silicon chips and power switching devices has applications for the gear inside most consumer electrical goods. Solar cells are another preoccupation: efficient harvesting of solar power for the grid.
