The Department of Hydrology and Atmospheric Sciences (HAS) at the University of Arizona invites applications for a tenure-eligible Assistant Professor in Hydrogeochemistry (broadly defined) to begin August 2025.  We seek areas of research and teaching that contribute to the advancement of process-level chemical understanding of hydrogeologic systems and their dynamics, combining observation, analysis and modeling. Areas of interest may include, but are not limited to, surface water-groundwater interactions, riparian areas, Critical Zone processes, catchment hydrology, and aquifer/confining unit dynamics. The distribution of effort will normally be 40% Research, 40% Teaching, and 20% Service. Research
