My research interests center on perception-action and cognitive development. In my recent work, I have been studying the development of tool use in children and how it might be related to the object manipulation skills of infants. Additionally, I have been conducting work on spatial cognition in children, focusing on how children code the location of objects and object features. Dr. Lockman’s research program can be found at https://childdevelopment.tulane.edu. Dr. Lockman is currently accepting graduate students.

Dr. Esposito's research interests include Hydraulics and Sediment Transport In River Deltas, Floodplain Sedimentation, Sedimentary Processes within Vegetation, Numerical Modeling of Coastal Morphology and Coastal Zone Management and Infrastructure

Research Projects

This project, developed in close collaboration with coastal restoration practitioners, aims to establish standardized data collection methodology for monitoring and predicting sediment transport within coastal wetland vegetation. The data collection efforts focus on the turbulence generated by marsh vegetation that can keep fine sediment from depositing even in low velocity environments. Restoration practitioners will be able to use the products of this project to improve predictions of marsh sustainability and better assess the effectiveness of restoration efforts.

My research focuses on understanding the processes and time-scales over which brittle faults grow, interact and evolve. This includes studying fault structure and patterns of displacement accumulation on faults, fault scaling relationships, and the temporal evolution recorded in basin stratigraphy and in landscapes.  Geographically, much of my work on fault evolution and tectonic landscape development has been within the Eastern California shear zone and in the northern Basin & Range. I also have projects in south Louisiana looking at recently active faults, how salt flow affects these faults, and the contribution of these processes to subsidence and coastal wetland loss.
