A.R. (Ravi) RavishankaraA.R. (Ravi) Ravishankara, Professor of Chemistry and Atmospheric Science

Dr. Ravishankara has worked over the past three and a half decades on the chemistry of the Earth’s atmosphere as it relates to stratospheric ozone depletion, climate change, and regional air quality.  His measurements in the laboratory and in the atmosphere have contributed to deciphering the ozone layer depletion, including the ozone hole; to quantifying the role of chemically active species on climate; and to advancing understanding of the formation, removal, and properties of pollutants.



Sonia Kreidenweis, Professor, Atmospheric Sciences, Colorado State University, May 13, 2013Sonia Kreidenweis, Professor of Atmospheric Science

Dr. Kreidenweis is a professor of Atmospheric Science at Colorado State University. She is also presently serving as Associate Dean for Research in the College of Engineering. Her research interests center on atmospheric particulate matter and its role in air quality and climate. In particular, she is interested in aerosol water contents and aerosol-cloud interactions for both liquid and ice clouds. She received her BS in chemical engineering from Manhattan College in 1983, and MS and PhD degrees in chemical engineering from the California Institute of Technology in 1985 and 1989, respectively.


Marilee Long
Marilee Long, Professor of Journalism and Media Communication
, Professor of Journalism and Media Communication

Marilee Long’s research interests are in health and science communication. Recent work has addressed media coverage of health and its effects on public support for health policy and on individuals’ behaviors, and the effects of media portrayals of science and scientists on adolescents’ attitudes toward science careers. She has been PI or co-PI on grants from the National Institutes of Health, National Science Foundation, Colorado Tobacco Research Program, among others. Her professional experience includes being a technical writer/editor in aerospace and engineering, and a writer in the public affairs office for a hospital and clinics. She is also a professor in the Colorado School of Public Health and a Fellow in the American Association for the Advancement of Science.
