Faculty Overview
Dr. Freedman’s major teaching and research interests include: hazardous waste management, water and wastewater treatment, and biodegradation/ bioremediation of recalcitrant organic compounds. Dr. Freedman's research focuses on the application of environmental microbiology to development of enhanced methods for biodegrading hazardous organic contaminants. Of particular interest is elucidation of biotransformation pathways and application of this knowledge to design of biological treatment processes. Current studies include evaluating the contribution of abiotic and biotic processes to natural attenuation of chlorinated ethenes in deep fractured sandstone, biodegradation of lindane, chlorinated benzenes, and chlorinated ethenes in fractured dolomite, microbial community response to enhanced in situ biotransformation of halogenated methanes, development of an enrichment culture for use in bioaugmentation of chlorinated ethene plumes at the Savannah River National Laboratory, characterization of microbes that anaerobically oxidize vinyl chloride, and the interaction of 1,2-dichloroethane and ethylene dibromide during anaerobic dihaloelimination.
