Personal profile


My research focuses upon air
pollution in California's National Parks and National Forests. Working
with colleagues from the National Park Service (NPS) and the United
States Forest Service (USFS), my students and I have conducted
extensive measurements of surface-level ozone in Yosemite National
Park, Joshua Tree National Park, and other NPS and USFS sites. Our
results have been published in journals such as Atmospheric
(e.g. "Surface  Ozone in Yosemite National Park" by Joel D. Burley
and John D. Ray, Volume 41, Issue 28, September 2007, pp. 6048-6062)
and have helped spawn multiple student research projects,
some of which have received local and/or national recognition.
