In this episode, we interview Dr. Rachel Chang. She’s an atmospheric scientist with the Department of Physics and Atmospheric Science.

Dr. Chang uses her background in engineering and chemistry to study aerosols in the air — where they come from, how they change and move around, and how they impact both current weather conditions and longer-term climate change.

This episode covers Dr. Chang’s path self-described “non-linear” path to atmospheric science, her family-focused upbringing in Scarborough, and how she uses our foggy weather here in Nova Scotia to do some of her research.
