Research Interests


Research Activities

Hyper-alkaline groundwater of Calumet wetlands (South Chicago, IL)

  • Geochemistry and microbial life in the highly alkaline Calumet region, Illinois (with Wesley Swingley, NIU Biological Sciences)
  • Remediation study- changes geochemistry influence microbial communities

Fate and transport of Antibiotics, Pharmaceuticals and Personal Care Produce

  • Surface water quality, including nutrients, bacteria, metals and antibiotics in the vicinity of confined animal feeding operations (CAFOs) (with Kendall Thu, NIU Anthropology)
  • Analyzing water samples collected from a local river used as a drinking water supply to determine if antibiotics are present. Determination if antibiotics have made it into river sediments and have the potential to infiltrate groundwater.
  • Natural attenuation of pharmaceuticals and illicit drugs in laboratory columns.

Research on groundwater in the Yucatan Peninsula (with Rosa Maria Leal-Bautista, Centro de Investigacion Cientifica de Yucatán)

  • Tracing groundwater flow in karst using chemical and biological indicators (with Jean McLain, University of Arizona, Water Resources Research Center)
  • Effects of tourism on Salmonella flagellar gene variation (with Mel Duvall, NIU Biological Sciences)
  • Analysis of the native microbial communities in sulfidic groundwater (with Mel Duvall, NIU Biological Sciences)
  • Determination of public health from use of recreational waters (with Tomoyuki Shibata, NIU Public Health)
  • Research Experience for Undergraduates: Investigaciones sobre el Agua: Research in water sciences in the Yucatan

Nachusa Grasslands

  • Conducting hydrogeological and geological study of the Nachusa Grasslands
  • Tracing groundwater flow near the soil boils using geophysics, geochemistry and physical flow (with Phil Carpenter, NIU Geology and Environmental Geosciences)

Microbiological Communities changes in different environments

  • Influences of biostratinomic and diagenetic processes on microbial preservation of primary soft tissues during the fossilization of bone (with Joe Peterson, University of Wisconsin, Osh Kosh)
  • Fate of Drilling Fluids during the South McMurdo Sound Project (SMS) of the Antarctic Geological Drilling Program (ANDRILL)

Geochemical Analysis

  • Stable isotope and geochemical analysis of surface and groundwater interactions in the Atacama Desert (with Justin Dodd, NIU Geology and Environmental Geosciences)
