Ellen K. Herman is an Associate Professor in the Department of Geology at Bucknell University in Lewisburg, PA. Ellen joined the faculty of Bucknell in 2006 after graduate work in karst hydrology with Dr. William B. White at Penn State University. Her work focuses on karst spring and cave systems in the Appalachians with particular emphasis on sediment transport and storm flow behavior. She works with a variety of professional collaborators as well as undergraduate students to consider theoretical and applied problems in karst hydrology. In addition to other on-going projects, she and her students will be working over the next 3 years with Dr. Laura Toran of Temple University and her graduate students on an NSF-funded study to re-visit the 1971 “Shuster and White “classic springs using continuous logging and finely spaced storm sampling to develop a robust classification system.
