Chan began his career as a tenure-track Assistant Professor at the University of Massachusetts at Amherst in 1985. With heart and mind always in Hong Kong, he came back in 1986, first in The University of Hong Kong (1986-92) and then in The Hong Kong University of Science and Technology (1993) before joining his Alma Mater in 1993.

Chan has published more than 90 journal papers and is in the ISI's List of Top 250 Highly-Cited Mathematicians in the world since 2004. He won a Leslie Fox Prize in 1989 at Cambridge in the United Kingdom; a Feng Kang Prize in 1997 in Beijing, China; and a Morningside Award in 1998 in Beijing, China. He has served on the editorial boards of more than 15 journals, including: Asian Journal of Mathematics (co-Chief Editor since 1997), Advances in Computational Mathematics (from 2010), Numerical Linear Algebra with Applications (since 2004), SIAM Journal on Imaging Sciences (since 2007), and SIAM Journal on Scientific Computing (served from 2000 to 2008). He also presented over 90 invited conference talks in more than 20 countries and reviewed papers for more than 60 different international journals.

His wonderful group of graduate students includes Michael Ng, who won an Honorable Mention in the Householder Prize Competition in 1996; Wai-Ki Ching, a prize winner of the 1998 Copper Mountain Conference Student Paper Competition; Chiu-Kwong Wong, a Sloan Dissertation Year Fellow in 1998; Hao-Min Zhou, who won an Honorable Mention in the Householder Prize Competition in 2002 and is an NSF CAREER awardee in 2007; and Zheng-Jian Bai, the Applied Numerical Algebra Prize Winner in 2008.
