Jessica Z LeRoy, Ph.D.

Dr. Jessica Z LeRoy is broadly interested in the physical processes that shape Earth's surface, and her research focuses on water and sediment flows in natural and human-influenced fluvial, lacustrine, and coastal systems.


Dr. Jessica LeRoy holds B.S. degrees from the University of Michigan in Physics and Earth Science, and M.S. and Ph.D. degrees from the University of Illinois in Physical Geography. Her research interests include field-based investigations of river morphodynamics and sedimentology, as well as the application of concepts in hydrodynamics to invasive species management issues. Jessica's graduate research focused on the co-evolution of flow structure and channel morphology in meander bends following chute cutoff events. During graduate school she also worked on projects addressing the hydraulic geometry of submarine channels, and the sedimentology of very fine grained meandering rivers. Jessica started at the U.S. Geological Survey as a Student Trainee in September 2015, and converted to a full time position as a Hydrologist in May 2016. Since joining the IL-IA WSC, Dr LeRoy has been a part of the Asian carp response team, and has participated in applied research on risk assessment and the development of control methods.
