Cheung graduated from the University of Brighton Faculty of Arts with a 3D Materials Practice BA(Hons) in 1994 and has gone on to a successful career which includes a senior lecturing post at Central St Martin's in London. She also remains in touch with the (now) College at Arts and Humanities at Brighton and is a regular visiting lecturer on the Design and Craft BA(Hons) course. Her design portfolio includes a large range of materials and objects including domestic items.
She was one of 100 designers invited by the London Organising Committee of the 2012 Olympic and Paralympic Games to submit their ideas for the new medals and won the competition to design the Paralympic Games medals. She based her design on the wings of a sculpture of Nike, the Greek goddess of victory, representing: “Spirit in motion, forward flight, power and lightness”.
Cheung said she was inspired by “the endurance, focus and achievement of elite Paralympic athletes”, explaining that "It was important that the medal has layers of meaning”. The independent judging panel chose the design from a six-strong shortlist because her design "held a narrative that befitted the athletes' achievements”.
