Katherine Skalak

The U.S. Geological Survey
United States Virgin Islands


Dr. Katherine Skalak studies landscape dynamics and fluvial geomorphology, focused on understanding and predicting changes in the patterns and functions of landforms in response to human impacts and restoration efforts. In particular, dynamics of fine sediment and particle associated nutrients and contaminants on varying temporal and spatial scales, and management effects on fluvial systems. Dr. Skalak received her undergraduate degree in environmental science from St. Joseph’s University. She received her master’s degree in Geology from University of Delaware in 2004. A National Science Foundation GK-12 fellow, she completed her Ph.D in Geological Sciences from the University of Delaware in 2009. She started as a post-doctoral researcher at U.S. Geological Survey in 2009 and became a Research Hydrologist in 2011.
