Charlene R. Crocker is a Research Scientist at the EERC, where her work focuses on CO2 sequestration public outreach, the sorbents for emission control strategies in fossil fuel-fired energy systems, environmental management and air quality, carbon-based flue gas sorbents, particulate matter (PM)-sampling protocols, water quality education, and bioassessment tools. She holds a B.S. degree in Chemistry from the University of North Dakota and a B.A. degree in French from Colby College, Waterville, Maine. Ms. Crocker’s principal areas of interest and expertise span public outreach and scientific research activities. Public outreach programs have focused on fossil energy transformations, CO2 emissions, water quality and use, and fish consumption advisories and include general public and K–12 education and documentary development, writing, and production. Research areas have focused on trace element emissions and control for fossil fuel combustion systems, with a particular emphasis on air pollution issues related to mercury and fine particulates. This includes developing carbon-based mercury control sorbents, mercury and halogens in coal combustion, and airborne PM instrumentation. Ms. Crocker has experience in water quality-monitoring and analytical methods; development and implementation of fish consumption surveys; general public and K–12 education; laser-induced breakdown spectroscopy (LIBS); atomic absorption spectroscopy (AAS) (flame, graphite furnace, and hydride generation); inductively coupled plasma (ICP) spectroscopy; trace element analysis of water, coal, and coal by-products; and atomic fluorescence spectroscopy (AFS).
