Professor & Chair
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 development of bioaugmentation cultures for chlorinated ethenes that grow at low pH, evaluation of bioremediation strategies to treat high concentration of halogenated methanes, use of biostimulation to enhance biogeochemical degradation of chlorinated ethenes in fractured sandstone, and studies to determine the anaerobic biodegradability of 1,4-dioxane.
