Research Summary
My inter-disciplinary research and graduate education programs in environmental/ecological sciences and engineering have covered diverse research interests that have spanned from lab-scale, process-level studies.

Current research and educational interests are focused on: (1) multi-scale modeling and analysis of landscape hydrologic and biogeochemical process linkages across human-impact gradients, including intensively managed croplands, urban catchments, and wetlandscapes, with pristine catchments serving as the reference; (2) resilience-based analysis of coupled natural and engineered complex systems, including food-bioenergy-water sustainability issues.

Past projects have involved development and use of models for research purposes and for decision making, with applications in catchment-scale water-quality analyses, and aquifer-scale studies on industrial land uses. assessments, groundwater vulnerability, contaminated site remediation, and watershed management.

Selected Research Projects

  • Enhanced flux-based characterization of contaminated aquifer sites

  • Fate and transport of pharmaceuticals and estrogens in croplands

  • Multi-scale catchment modeling of coupled hydrologic and biogeochemical processes

  • Resilience-based design of coupled industrial-natural systems
