Research Interests
Dr. Lewis Semprini’s research focuses on biological processes for the treatment of hazardous wastes, the fate and transport of organic contaminants in the environment, water and wastewater treatment, and molecular methods applied to microbial processes. He specializes in field, laboratory, and modeling studies of aerobic and anaerobic processes for treating chlorinated solvents. His current research projects include a DOD funded “Molecular Biomarkers for Detecting, Monitoring and Quantifying Reductive Microbial Processes,” a NSF funded project “Global Transcriptional Responses in Nitrogen Cycling and Nutrient Removal Processes and Development of Supplemental Instructional Workshops,” and a SNNI funded project “Identifying the Inhibition and Expression of Sentinel Genes of the Bacteria N. Europaea Upon Exposure to Metal Oxide Nanoparticles.”
