Jennifer McIntosh


  • Fellow
  • Earth 4D: Subsurface Science & Exploration




Jennifer McIntosh’s research focuses on understanding how water changes as it moves through the Earth.

She is particularly interested in tracers of hydrologic and biogeochemical processes from the earth’s surface to deep subsurface environments, the origins of fluids in the earth’s crust, the extent of groundwater resources and the environmental impacts of oil and gas production.  Her research involves extensive field sampling, laboratory analyses, and geochemical and hydrologic modeling.
