Research Focus: Freshwater salinization has been shown to affect much of temperate North America and Europe. Positive trends in freshwater specific conductance, base cations and pH have been observed in datasets spanning the past 50 years. However, little is known about the effects of salinization at smaller temporal timescales. Preliminary results indicate that salinization induces both base cation exchange and increased metal mobility during and after winter precipitation events. Salts may also be accumulating in groundwater and soils surrounding road networks, never being fully flushed out of the system during the summer and fall.

Research Focus: I am studying organic matter sources and composition, and how they affect nutrients, organic contaminants, and heavy metals in aquatic environments. I am investigating the effects of climate change and watershed landuse on water quality of streams, and using Soil and Water Assessment Tool (SWAT) to predict future changes in nutrient and carbon inputs from land to the coastal ocean. I am also interested in hydrological model developments for tracking sources and in-stream processing of organic matter and nutrients.
