Effects of Air Pollutants and Global Climate Change on Plants
Since 1972, I have conducted interdisciplinary research on atmospheric processes and the effects of air pollutants (e.g., ozone, sulfur dioxide) on crops and trees. My research emphasizes the integration of atmospheric chemistry, meteorology, air pollutant removal or deposition processes and vegetation response functions. My most recent research is directed to integrated modeling of crop yield responses under ambient field conditions to whole growth season dynamic or random variability in exposures to multiple air pollutants (ozone, sulfur dioxide etc.) and climate (solar radiation, temperature, precipitation etc.)
I am also examining the percent contributions of specific pollutant sources to the regional scale air quality and their impacts on the foliage and growth of native pine species. That research has a direct relevance to the development of pollutant emission control regulations to protect the environment.
Since 1987, I have been an Associate Editor (Atmospheric Processes and Terrestrial Effects Modeling Sections) of the Journal "Environmental Pollution" and I am also the Chief Editor of the Book Series "Developments in Environmental Science", both published by Elsevier Science, Amsterdam, The Netherlands.
