Dr. Jeffrey Hyman is the primary developer of dfnWorks, which has been applied to a wide range of applications including nuclear waste disposal, carbon sequestration, unconventional hydrocarbon acquisition, and geothermal energy extraction. He holds a PhD in Applied Mathematics and PhD minor in Hydrology and Water resources and has a unique background in applied mathematics (specifically numerical methods and stochastic processes), model design and development, and system analysis.

Dr. Carl Gable is Group Leader of Computational Earth Science at Los Alamos National Laboratory. He has spent most of his scientific career focused on mesh generation, model setup, and computational geometry. His focus on the dfnWorks team is developing automated methods to mesh discrete fracture networks (DFN) and discrete fracture matrix (DFM) systems.

Dr. Satish Karra is the Team Leader of the Subsurface Flow and Transport team in EES-16 at LANL. He oversees the development of the flow and reactive transport solver PFLOTRAN at LANL and its integration within dfnWorks. He also develops the dfnWorks Python interface pydfnworks that integrates various dfnWorks components and streamlines the overall workflow.

Dr. Nataliia Makedonska is a scientist in the Computational Earth Science group (EES-16), at Los Alamos National Laboratory. Her expertise lies in numerical modeling of subsurface flow and transport in 3D discrete fracture network; simulation of contaminant transport from potential leakage at nuclear waste repositories; hydraulic fracture modeling and prediction of natural gas production at oil&gas reservoir; flow modeling at geothermal sites; modeling of CO2 migration through fractured caprock at CO2 storage reservoir. Nataliia is a developer of dfnWorks software; a core developer of dfnTrans: Lagrangian particle tracking and transport model in 3D DFN.

Dr. Matt Sweeney has a PhD in geology from the University at Buffalo and is interested in computational fluid dynamics and understanding multiphase geological flows. As part of the dfnWorks team, he works on improving the capabilities of modeling coupled fracture-matrix systems including continuum and explicit approaches.

Daniel Livingston is a Research Technologist in the Computational Earth Science (EES-16) group at Los Alamos National Laboratories. His work involves computational geometry and machine learning for geophysical applications, GIS data analysis/visualization/manipulation, and mesh generation for finite element multiphysics simulators. He holds a Master’s degree in Nanoscience from ASU, a B.Sc. in Physics from NMSU, and is in progress to earning an M.Sc. in Computer Science from Georgia Tech.

Dr. Hari Viswanathan is a senior scientist with expertise in flow and transport modeling in porous and fractured media. He has worked on a broad set of subsurface applications that include oil and gas, carbon sequestration, nuclear waste disposal and nuclear nonproliferation. His projects have utilized dfnWorks to discover mechanisms controlling hydrocarbon extraction and CO2 and Rn leakage.
