Robert Dudley
Robert Dudley is a Supervisory Hydrologist in the New England Water Science Center.
As Chief of the Statistical and Geospatial Section, New England Water Science Center, Rob manages a diverse team of scientists involved in a wide range of interpretive water-resources investigations that include water use, quantity, and quality, geospatial applications, and remote sensing. His project work has focused on regional and national-scale statistical investigations of trends and variability of surface waters and groundwaters, and developing methods for estimating river flow using satellite imagery and altimetry data.
