Primary Research Interests

• Impacts of global change and emerging contaminants on groundwater sustainability
• Integrative study of hydrologic and ecological processes at watershed scales
• Field, laboratory, and theoretical studies of the effects of aquifer heterogeneities and preferential flow paths on contaminant transport processes
• Coupling of physical transport processes with biological and geochemical reactions for modeling of contaminant transport and remediation

Recent and Ongoing Research Projects
