Overview

Research Statement

My group applies its strong foundations in physics, mathematics, computational methods, and engineering towards solving problems pertaining to flow and particle transport in the environment.  We work at the interface between theory, numerical simulation, and experimentation.  We develop and use models for multiphase flow in porous media and examine transport of solutes, colloids, pathogens therein.  Our numerical approaches, which include lattice-Boltzmann and pore-network modeling, can address a very broad range of transport scenarios.  Recent and current research projects include

  1. Effects of bacterial chemotaxis on contaminant degradation in subsurface environments,
  2. Colloid and pathogen transport in subsurface environments and water filteration systems,
  3. Spreading of antibiotic resistance in poultry-waste impacted soil,
  4. Dynamic effects in capillary pressure for multiphase flow in porous media, and
  5. Effects of seismic waves on multiphase flow.

Most recently, I have also begun research that will allow for a more comprehensive exposure assessment of contamination of residential areas by hydrocarbon-contaminated flood waters, and soil contamination by small but chronic hydrocarbon spills.
