CRB-CZO Alum: Former Post Doctoral Researcher. Quantifying surface water-groundwater interactions in rivers and coastal settings to understand implications for solute and heat transport. In particular, I am interested in dynamic processes such as storms and tides that enhance surface water-groundwater exchange.
