Dr. Jennifer C. McIntosh is an Associate Professor in the Department of Hydrology and Water Resources at the University of Arizona (UA), a Joint Faculty member in the UA Geosciences Department, and an Adjunct Research Geologist with the United States Geological Survey. Her areas of research include solute and isotope tracers of hydro-biogeochemical processes from the earth’s surface to deep subsurface environments; origins of saline fluids and natural gas; sources of groundwater contamination (natural and anthropogenic), and impacts of continental glaciation on groundwater resources. Dr. McIntosh has served on several External Advisory Boards, including the Energize New Mexico NSF EPSCoR project, and has been an invited participant in multiple NSF, EPA, and IAEA technical workshops related to development of new groundwater age tracers, hydraulic fracturing, and reactive transport modeling of biogeochemical processes. She is currently an Associate Editor (AE) for Water Resources Research and has served as a past AE for Hydrogeology Journal.
