Current Courses

  • Contaminant Fate and Transport in Soil
  • Environmental Soil Physics


  • We are interested in measurement, modeling, and interpretation of mass transport and transformation in soil and other environmental systems. Our current research areas include: (1) colloid (natural colloids, nanoparticles and microorganisms) retention and transport in saturated and unsaturated soils; (2) colloid mobilization and its relation to biogeochemical cycling of organic carbon in redox-active environments (e.g., wetlands); (3) fate and bioavailability of colloidal phosphorous released from agricultural sources in watersheds; (4) effects of physicochemical properties and hydrological processes on microbial contamination of fresh produce; and (5) biophysics of the rhizosphere.
