Post-Doctoral Research Associate - IWH

Postdoctoral ResearcherThe Institute for Water and Health (IWH) at Georgia Southern University seeks a motivated postdoctoral researcher to support groundwater modeling and hydrogeology in ongoing projects across Southeast Georgia. The successful candidate will lead groundwater research projects focused on coastal aquifers and saltwater intrusion. The position combines numerical groundwater modeling, field monitoring of well water levels and salinity, and data science to understand how aquifers respond to pumping, sea level, and climate. The postdoc will also conduct solute fate and transport modeling, publish results, and communicate findings to agencies and stakeholders. This position is time limited and 100% sponsored-funded; therefore, continued employment is contingent upon availability of grant or contract funding.Design, install, and maintain a field well-level monitoring network, including pressure transducers, data loggers, and manual water-level and specific conductance measurements Develop, calibrate, and apply numerical groundwater flow models (e.g., MODFLOW 6) to evaluate aquifer conditions and water resources Develop variable-density models (e.g., SEAWAT, SUTRA, or MODFLOW 6) to assess saltwater intrusion in coastal aquifers and evaluate management scenarios Conduct solute fate and transport modeling to evaluate the movement of salinity and contaminants in groundwater Manage, quality-check, and analyze monitoring data using statistical and data science methods (time series analysis, trend detection, spatial analysis) in R or Python Prepare technical reports, peer-reviewed manuscripts, presentations, and summaries for agencies and stakeholders Contribute to grant proposals and help train students in field and modeling methodsPhD degree in a relevant field (hydrogeology, hydrology, civil or environmental engineering, geology, or a closely related field), completed by the start date Demonstrated experience developing and calibrating numerical groundwater flow models (e.g., MODFLOW) Demonstrated experience collecting groundwater field data Demonstrated experience analyzing environmental data in R or PythonPh.D. research focused on coastal hydrogeology Variable-density modeling of saltwater intrusion (SEAWAT, SUTRA, or MODFLOW 6) Fate and transport modeling (MT3D-USGS, MODFLOW 6 GWT, or FEFLOW) Model calibration and uncertainty analysis Record of peer-reviewed publications$65,000 This is an exempt position paid on a monthly basis.Resume Cover Letter Two (2) Professional ReferencesConsistently exhibit engaging customer service Ability to support various constituencies served by the University Proven proficiency with computers including Microsoft Office, Google, and/or applications as required for specific position Demonstrated ability to work independently and complete tasks Ability to explain technical results to non-technical audiences Adhere to University policies and procedures to meet Institutional goals and support University's mission for student success Knowledge of coastal aquifer hydrogeology and groundwater¿surface water interactions Demonstrated research experience from designing research questions to dissemination of results Effective communication (verbal and written), organizational and human relations skills Skill in statistical analysis, time series analysis, and data visualization Strong attention to detail with excellent analytical, judgment, and problem-solving capabilitiesOpen Until Filled Application review may begin on November 11, 2026.
