Research and Interests
- Dr. Cox’s research has focused on the formation of the Antarctic ozone hole, and on issues related to global warming. She has studied the interaction of aerosol particles with sunlight, an important component in controlling the radiation budget of the earth, and one that has received much attention for its role in “global dimming”. Dr Cox has presented papers and authored articles on the retrieval of atmospheric data from satellite experiments, aerosols, stratospheric ozone depletion, climate change, carbon sequestration, the use of GIS in sustainability studies, and energy resources. She enjoys educating students in important environmental issues such as air pollution, acid rain, ozone depletion and global warming. She has a keen interest in the environment and enjoys following scientific developments in understanding climate change, and in viewing the public and political response to this change. She teaches courses related to the atmosphere, climate change, alternative energy resources, sustainability, remote sensing, and the environment. As Director of the CSUN Institute for Sustainability she coordinates sustainability initiatives on campus including the development of sustainability programs and research.
