We study coupled flow processes in porous and fractured media across multiple scales. Field-scale subsurface processes are determined by the collection of coupled processes occurring at smaller scale. We investigate small-scale coupled processes and transfer the knowledge across multiple scales to develop upscaled modeling frameworks. The new modeling frameworks will not only capture coupled, nonlinear phenomena, but also provide frameworks for subsurface characterization through joint inversion.

Our research directly contributes to addressing real world problems such as subsurface contaminant transport, reservoir characterization, managed aquifer recharge, in-situ bioremediation, and clogging in porous media. Please email me if you are interested in joining my research group. I have open positions for graduate students, and we welcome visiting students and scholars.

Examples of ongoing research projects are:

  • Upscaling transport, mixing, and reaction in porous and fractured media
  • Modeling complex biogeochemical reactions in fractured media
  • Density effects on flow, transport, and mixing in fractured media
  • Inverse problems for subsurface characterization
  • Microfluidics experiments for visualizing biochemical processes in porous media
  • Aquifer storage and recovery
  • In-situ bioremediation of contaminated fractured aquifers
