Sun-chang Lo was born in Guangzhou, China, and has lived and studied in Taiwan, Japan, Hong Kong and the United States.

Following graduation from the Cooper Union, New York City, in 1972, he was a recipient of the Japanese Monbukagakusho Scholarship from 1974 to 1976. While studying under Kazuo Shinohara at the Tokyo Institute of Technology, analysis and synthesis of the theories and histories of Chinese and Japanese architecture landed him two consecutive awards in the 1975 and 1976 Japan Architect International Residential Competitions.

From 1977 to 1979, while participating in the Lukang Landmark Preservation Project, he taught architecture and design at Tunghai University, Taiwan. Back in his New York City home base, he and his wife/partner, Jean, pursued a busy freelance design practice ranging from architecture, interior, fashion and graphic design, to photography, surveying and model making.

From 1993 to 2008 he taught photography, design, art and architecture at the Department of Architecture at the University of Hong Kong.

He is presently a freelance architect/artist/photographer.
