Danielle Haas Freeman, Ph.D.

Assistant Professor, Chemical and Environmental Sciences Department of Science

CGA wordmarkProf Freeman is an environmental chemist and a teacher. In lab, she studies where chemicals go and how they behave when they are released to the environment. Her primary research focuses on sunlight-driven reactions that transform organic chemicals in natural waters, changing their behavior and effects. Her work on crude oils has shown that sunlight exposure can change the chemistry and physical properties of oil spilled in the ocean, with implications for damage assessments and effective cleanups when an oil spill happens at sea. In the classroom, Prof Freeman uses active learning techniques to teach chemistry and oceanography coursework.
