Current Projects:

  • VOC pollutant source, transport and fate assessments in urban settings.

  • Freshwater availability on arid islands (Catalina, California)

  • The effects of submarine groundwater discharge on coral reef health on Mo'orea, French Polynesia.

  • Aquifer pollution vulnerability in agriculture-dominated areas in Central California. 

  • Droughts and water quality: mobilizing geogenic pollutants through drought-induced changes and groundwater redox potential.


  • March 2022: New paper on groundwater recharge on Catalina Island published in water.

  • February 2021: New paper on climate change effects on groundwater trends published in water.

  • December 2020: New paper on objective baseflow estimation published in Journal of Hydrology.

  • June 2020: New paper on sub marine groundwater discharge published in Hydrogeology Journal.

Research Focus - Assessing Sustainability Quantitatively:

California has been impacted by years of drought and population growth that challenge its water supply. We apply chemical tracers, numerical models and GIS to analyze stressed watersheds and study the evolution of freshwater from its source to its discharge points.
