My students and I use traditional microbiological methods in combination with cutting edge molecular techniques to cross into several areas of environmental engineering research. These areas include water and wastewater treatment (e.g. molecular characterization of nitrification inhibition by priority pollutants), risk assessment (e.g. ecotoxicity of nanoparticles and oil dispersants) and alternative energy development (e.g. the production of methane, hydrogen and ethanol from the anaerobic treatment of wastewater). Some of our current research projects include:
- Nanotoxicity on environmentally sensitive microorganisms: Understanding the potential toxic effect of released engineered nanoparticles (e.g. silver nanoparticles) to beneficial microorganisms in wastewater treatment plants and the natural environment.
- Ecotoxicity of oil dispersants and the resulting dispersed oil in the Gulf of Mexico: Identifying how the use of oil dispersants during the 2010 Gulf of Mexico oil spill influences the toxicity of the released crude oil to nitrogen cycling bacteria.
- Microbial ecology of engineered wetlands: Identify how environmental factors (e.g. flow rates, nutrient concentrations, carbon sources, etc.) influence the microbial ecology (and resulting functionality) of wetlands built to treat run off water from the San Diego Zoo Animal Safari Park.
- Anaerobic treatment of wastewater: Using anaerobic microorganisms to treat wastewater to California reuse standards and while simultaneously producing alternative fuels, including methane, ethanol and hydrogen.
