Research Interests

Enhanced river chemical loads have the potential to release stored nutrients and metals from sediments, alter weathering rates, decrease biodiversity, and jeopardize public health. The magnitude and frequency of these chemical inputs may be amplified in the near future due to the interactive effects of climate variability, urban population growth, and land use changes.

I am investigating the spatial and temporal trends in anthropogenic inputs of base cations to urban rivers, the hydrologic controls on these inputs, and the subsequent perturbation on stream chemistry and biogeochemical cycles. My research is concentrated on urbanized watersheds in the Baltimore-Washington Metropolitan area and couples laboratory (ex-situ) experiments with high-frequency sensor data; all within the urban watershed continuum and urban evolution frameworks.
