Christopher Zahasky

Assistant Professor of Geoscience

College of Letters & Sciences

Dr. Christopher Zahasky is an assistant professor in the Department of Geoscience and the principle investigator of the Subsurface Hydrophysics Lab at the University of Wisconsin–Madison. He also has affiliate faculty appointments Geological Engineering and the Nelson Institute for Environmental Studies. He received his Ph.D. in energy resources engineering from Stanford University and completed his postdoctoral training at Stanford University and the Imperial College London.

Dr. Zahasky's research focuses on the fundamental physics and mechanisms of fluid, gas, and colloid transport processes in heterogeneous porous and fractured media. His work has important applications across a range of environmental and geological processes including heat recovery in geothermal energy systems, bacteria transport in the subsurface, carbon capture and immobilization in geologic carbon storage projects, and fluid and contaminant entry and travel through the subsurface.

  • Contaminant hydrogeology - the study of how fluids and contaminants enter and travel through the subsurface
  • Carbon capture and storage - a technology for mitigating emissions from fossil fuel power plants and large industrial point sources
  • Conventional and unconventional energy resources - hydraulic fracturing processes for extracting shale gas and oil, geothermal energy production, and nuclear waste storage
