My work focuses on the collection of surface water flow and continuous water quality data. More recently this work has been extended to research the use of using surrogate models to estimate concentrations and loads for several different water quality constituents, including suspended sediment and chloride.  I've participated on several high-water mark and surveying campaigns related to large flood events following severe storms, including Hurricane Maria in Puerto Rico.
