Belinda Siew-Woon Chang is an American-Canadian evolutionary and molecular biologist. She is currently a professor in the Department of Ecology and Evolutionary Biology and the Department of Cell and Systems Biology at the University of Toronto. Chang was also a Canada Research Chair in Comparative Evolutionary Neurobiology from 2003 to 2013.
