Dylan Harp is a computational hydrogeologist. He designs and implements data analysis, analytical and numerical simulators, and uncertainty quantification algorithms for hydrogeological investigations. His areas of research include groundwater flow and contaminant transport, CO2 sequestration, nuclear waste disposal, permafrost degradation, gas migration from underground nuclear explosions, and geothermal energy development.

Dylan utilizes and develops the following groundwater flow and transport simulators:

  • FEHM, Finite Element Heat and Mass Transfer
  • ATS, The Advanced Terrestrial Simulator
  • Amanzi, The Advanced Simulation Capability for Environmental Managment (ASCEM) simulator

Dylan is the primary develop of:

  • MATK, Python Model Analysis ToolKit package
  • PyLaGriT, Python frontend for the Los Alamos Grid Toolbox (LaGriT)

Dylan is a codeveloper of the uncertainty quantification code Model Analysis and Decision Support, MADS and the Uncertainty Quantification toolkit (UQuant) within the ASCEM project.  

Dylan also uses the following uncertainty quantification tools to solve hydrogeological problems:
