David Cheung is a multimedia artist whose artwork often deals with social, political issues and involves audiences, public as active participants.

He has exhibited in Canada and Internationally at private galleries, art festivals and public museums.

In 2002, he found ARTi-Smoking, a non-profit organization that uses creative methods and art to enhance youth and public awareness about the dangers of smoking and the epidemic magnitude of tobacco-use related deaths to gather public support to campaign for a "tobacco free world".

Currently he is engaged in a project entitled Rocky Railway High (Closure), an interactive art project for the symbolic return of the Chinese railway workers who perished during construction of the Canadian Pacific Railway between 1881-1885, to their homeland Guangdong, China (an important Chinese custom at the time).

Besides using art for social projects, he also has been pursuing research in fusing Chinese classical ink and wash landscape paintings with Western oil paintings.

He is also an independent curator who has curated exhibits Internationally.
