Leigh Canham is a British scientist who has pioneered the optoelectronic and biomedical applications of porous silicon.
His early work in this area took place at the Royal Signals and Radar Establishment in Malvern, Worcestershire.
Canham and his colleagues showed that electrochemically etched silicon could be made porous.
This porous material could emit visible light when a current was passed through it (electroluminescence).
According to the pSiVida web site, Canham is the most cited author on porous silicon.
