We strive to improve understanding of the physical/chemical/biological mechanisms that control fluid flow through porous and fractured media. We combine quantitative laboratory experimentation, which includes innovative approaches for imaging pore-scale to column-scale processes, with development of parallel, scalable computational models. Integrating experiments and computational simulations in this way allows us to develop well-tested mechanistic models of subsurface processes, providing a robust means for extrapolating laboratory-scale observations to field-scale systems of interest. Our fundamental research supports a range of problems involving subsurface fluid flow and transport processes, including:

• • Fate and transport of contaminants in groundwater
  • Remediation of contaminated groundwater
  • Subsurface CO₂ sequestration
  • Nuclear waste isolation
  • Geothermal energy production
