Short Biography

Welcome to Carolyn's professional page.  My career began with research on glaciers, principally those gracing our Cascade Range volcanoes, and later on glacier-related floods and debris flows.  Witnessing the May 18 1980 eruption of Mount St. Helens and taking part in the response set the course for several fascinating scientific projects. It also provided a front-row seat for observation and reflection regarding the role of science in society.  As CVO's Outreach Coordinator, I work in partnership with public officials, emergency planners, media, park interpreters, and educators to advance the cause of volcano preparedness.  Some earlier career choices have informed current work, including several years of teaching in a US public school and a private school in Kathmandu, Nepal, and working for the National Park Service.  My education continues daily through partnership projects and communications with the media, officials, and the public.

Favorite Quote:  "[Scientists] must use the same ingenuity and creativity in dealing with information for the public that they use in solving scientific problems.  When this falls short, even excellent scientific results may be nullified."  

Don Peterson, former Scientist-in-Charge at USGS CVO  From:  D.W. Peterson, 1988 Volcano hazards and public response: Journal of Geophysical Research, Vol 93, No B5 pages p.4161-4170.
