NCEA supports an active postdoctoral program providing federal research experience to up-and-coming environmental scientists. The Center currently supports a variety of postdoctoral professionals and seeks applications for this latest position. Appointments are for 3 years and include a full package of benefits.NERL Post-Doctoral Research Program
The Environmental Protection Agency's (EPA'S) National Exposure Research Laboratory (NERL) is accepting applications for approximately 8 federal, three-year post-doctoral research positions. NERL has opportunities for conducting high priority research that contributes to protecting human health and the environment. Our primary focus is research and development that leads to improved methods, measurements and models to assess and predict exposures of humans and ecosystems to harmful pollutants and other conditions in air, water, soil, and food. Candidates will engage in areas such as environmental monitoring and characterization; exposure reconstruction; computer modeling of the transport, transformation, and fate of pollutants in multiple media and at multiple scales; human and ecological exposure analysis; remote sensing applications; and landscape ecology. The interdisciplinary nature of our research affords numerous opprtunities for collaboration with other researchers both inside and outside of EPA. The application period is November 29, 2007 through January 31, 2008.Environmental Technology Verification Report, Removal of Synthetic Organic Chemical Contaminants in Drinking Water, RASco, Inc., Advanced Simultaneous Oxidation Process (ASOP) (PDF) September 2007 (41 pp, 660KB, About PDF) | Verification Statement (PDF) (5 pp, 88 KB, About PDF)
