Dr. Jo Archibald got her PhD in Biological and Environmental Engineering from Cornell University, where she focused on watershed modeling and hydrology. While there she developed a web-based tool to help farmers determine the high-pollutant risk areas before runoff events. She is a contributor to the EcoHydRology package in R - an open source toolbox for ecological and hydrological data analysis, and is currently working on a model to improve road-stream crossing risk estimation.
