My research interests are in the role of terrestrial and oceanographic forcings on coastal groundwater dynamics, groundwater resources, and chemical fluxes to the coastal zone. A primary goal is to understand links between physical groundwater flow and biogeochemical processes in nearshore aquifers across temporal (waves to climate) and spatial (beach to bay) scales.



Postdoctoral researchers

Neshat Movahedi
PhD Hydraulic Structures Engineering, Gorgan University
MS Hydraulic Structures Engineering, Gorgan University
BS Water Engineering, Gorgan University

Neshat's research interests are experimental and numerical modeling of surface water and groundwater interactions. During her PhD, she conducted extensive laboratory experiments investigating hyporheic exchange caused by variations in channel bed and width. As a postdoc researcher, she aims to investigate how surface water dynamics affect exchanges of fresh and saline fluids in estuaries.


Graduate Students

Madelaine Griesel
PhD Student
BS, Physics, Trinity University

Madelaine’s interests are in modeling groundwater dynamics in estuaries. She is currently focusing on saltwater intrusion into groundwater and aquifers in various estuaries on the East Coast of the USA, with a goal to understand how groundwater-surface water exchange may impact water resources.






Asim Roy
PhD Student
MS, Geology, University of Dhaka BS, Geology, University of Dhaka

Asim Roy received an NST (National Science and Technology) fellowship to conduct his research in coastal Bangladesh while a MS student at the University of Dhaka. His current research interests are in coastal hydrodynamics, surface water-groundwater interactions, and extensive groundwater modeling. Out of academic study, he is a photographer, and he likes to travel, hike, and read novels.

Josh Griffin
MS Student
BS, Marine Science, Safety, and Environmental Protection, Massachusetts Maritime Academy

Josh is interested in tidally-driven groundwater-surface water exchanges and water quality.
