Air and Climate Change Research
Chris Geron is a senior scientist in the US EPA Office of Research and Development, National Risk Management Laboratory, Air Pollution Prevention and Control Division, (APPCD), Atmospheric Protection Branch (APB). Mr. Geron received an M.S. degree in Forestry from North Carolina State University and a B.S. degree in Forest Resource Management from Ohio State University.
Prior to joining EPA, Chris worked as a Quality Control Specialist for Mantech International Corporation in Corvallis, OR, from December 1988 until September 1989; as a Research Forester for the USDA Forest Service in Research Triangle Park, NC, from December 1986 until December 1988; and as a Research Assistant for North Carolina State University, Department of Forestry in Raleigh, NC, from August 1984 until December 1986.
Chris joined the Air Pollution Prevention and Control Division in September 1989. Current responsibilities include conducting research and managing research projects to estimate forest and agricultural ecosystem fluxes and effluxes of radiatively important trace gases, reactive organic compounds, particulate matter, and NOx. Specific responsibilities include landuse/landcover characterization, assessing emission rates of biogenic trace gases from forest and agricultural fields, estimating emissions from biomass burning, and quantifying the potential of biomass as energy feedstocks.
Chris' main interests are in landscape ecology, ecosystem dynamics and function, and trace gas exchange. Relating environmental variables to regional land cover and soil characteristics, net primary productivity, trace gas exchange, and site characteristics are among the areas he currently pursues. Chris is also interested in the economic potential of managing natural systems for sustained use of natural resources. Other areas of interest include development of rational schemes to extrapolate data (productivity, emission rates etc.) collected at small scales to landscape or regional scales. These concepts are often applied to emission modeling, such as those from natural VOC sources.
