ENVR 640- Environmental Exposure Assessment

Research Activities

Develop field sampling and extraction methods for organic compounds in biological and environmental media. Develop sample concentration and analysis laboratory methods for measuring and identifying patterns of endogenous and chemical biomarkers in human biological fluids including blood, breath, exhaled breath condensate, bronchial lavage fluid, and urine using gas chromatography – mass spectrometry (GC-MS) and immunochemistry platforms. Construct mathematical, statistical, and systems biology approaches to interpret the absorption, distribution, metabolism and elimination of human exposures to environmental stressors. Mentor Ph.D. students and post-doctoral fellows and teach Environmental Exposure Assessment at UNC School of Public Health.
