Current Research Projects

  • Characterizing silver nanoparticle toxicity towards Nitrosomonas europaea: Understanding the risk posed by nanotechnology to nitrification in engineered and natural systems.
  • Enhancing methane production in wastewater anaerobic digesters through the co-digestion of fats, oils and grease (FOG).
  • Investigating the development of antibiotic resistance in environmental bacteria exposed to environmental concentrations of pharmaceuticals.

Completed Research Projects

  • Determining the ecotoxicity of oil dispersants and the resulting dispersed oil in the Gulf of Mexico.
  • Creation of nitrification inhibition biosensors: Identification of 'sentinel genes' to indicate the presence of heavy metals and aromatic hydrocarbons.
  • Probing the global gene expression patterns of unsequenced microorganisms: The creation of a novel shotgun DNA microarray.
