Career
Chang is an Associate Professor at the Department of Physics & Atmospheric Science, at Dalhousie University. Her research explores how carbon cycles in and out of the ocean, including which factors impact the absorption of carbon dioxide into the ocean. In collaboration with the Environment and Climate Change Canada, Chang's research also includes studying particles in the atmosphere to understand their effects on air quality and visibility, such as measuring air particles before, during and after fog, and testing the chemical composition of fog water.

In 2017, Chang was appointed as a Canada Research Chair (Tier II) in Atmospheric Science. Her appointment was renewed in 2021. Chang's research has also been supported by the Canada First Research Excellence Fund.

To date, Chang has published over 90 academic publications, which have been cited over 3,500 times, resulting in an h-index of 33.
