Jo Shien Ng works to develop more and more sensitive electrical components called 'avalanche photodiodes' used in everything from satellites that look at the Earth from space, to body scanners in hospitals and airports. She does this by applying an understanding of the behaviour of materials developed through secondary and further education at a Chinese school in Malaysia, and a degree and PhD at the University of Sheffield, UK.
She explains that she is not intimidated by being often the only female scientist in technical meetings -- her expertise is clear: "What I say goes".
