Jessica Z LeRoy, Ph.D.

Dr. Jessica Z LeRoy is broadly interested in how water shapes earth's surface in natural and human-influenced fluvial, lacustrine, and coastal systems. 


Dr. Jessica LeRoy's research interests include fluvial, lacustrine, and coastal morphodynamics, sedimentology, and ecohydraulics. She has expertise in using hydroacoustic methods to measure water velocities and bathymetry. Jessica's graduate research at the University of Illinois focused on the co-evolution of flow structure and channel morphology in meander bends following chute cutoff events. She has also studied the hydraulic geometry of channels in low gravity environments (e.g. submarine channels and martian channel features) 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 USGS, she has participated in applied research aimed at mitigating the spread of bigheaded carps (Asian carp), as well as projects focusing on scour at bridge piers, beach replenishment, and reservoir sedimentation.
