Research Interests: Fate and transport of ground water contamination and ground water supply sustainability.

Current projects: Developing low cost methods for characterizing bedrock fracture flow conditions. Use of indigenous bacteria as a groundwater tracer tool. Impact of legacy arsenic pesticide use on groundwater contamination. Improving methods for sampling domestic wells for groundwater contamination. Application of the Dissolved Oxygen Alteration and Single Packer Methods for characterizing fracture flow conditions in crystalline rock using non-vertical boreholes.
