As a sedimentologist and geomorphologist with a BSc and MSc in Geosciences (University of Bonn, Germany), I am passionate about increasing our understanding of how sedimentary systems are controlled by environmental and external factors acting within different parts of their superordinate source-to-sink system, and the interplay of sediment transport dynamics and topography in both terrestrial and marine environments.

Building on my PhD research of process-response relationships in submarine canyons and shelf-edge deltas in a source-to-sink context at the University of Leeds (England, United Kingdom), I am currently investigating the co-evolution and mutual influence of Late Quaternary clastic and carbonate source-to-sink systems along the modern Belize continental margin to identify key mechanisms driving the geomorphology and stratigraphic record of mixed siliciclastic-carbonate margins associated with rivers and barrier reef systems.

I began my academic journey in geosciences with a Bachelor’s degree in Geology from the University of Dhaka, Bangladesh, followed by a Master’s degree in Geology and Natural Resources from Ball State University, USA. My Master’s thesis research delved into hydrologic modeling using SWAT+ to quantify streamflow response to wetland changes and hydrological alterations resulting from dam removal in watersheds. I have a strong interest in comprehending sediment movement and geomorphological changes in fluvial systems. My current research project is aimed at investigating geomorphological evolution through the development of a 1-D morphodynamic model integrated with remotely sensed data. This research seeks to enrich our knowledge of how dam disruptions impact sediment dispersal, channel bed evolution, and floodplain inundation

I started my academic studies pursuing a Bachelor’s degree in Civil Engineering, and I found myself interested in water science. I continued to study water engineering for a Master’s degree at the Amirkabir University of Technology in Iran. During this time, my research explored sediment transport around armored obstacles in rivers, including bridge piers and abutments. My thesis assessed drag coefficients and force balance exerted on bridge abutments in waterways. My current science research seeks to gain further knowledge of fluvial systems, combining geoscience perspectives and engineering viewpoints. I intend to study river morphology, how river channels grow and evolve during avulsions process, specifically related to channels accommodating ever greater water and sediment flux.

My research interests are primarily in sedimentology and river dynamics in high-latitudes environments. As an undergrad at Colorado State, I was part of a project using sediment geochemistry to understand sediment contributions of tributaries into larger river networks during rapid erosional events. Currently I am working on a project as an M.S. student/RA attempting to build an understanding of the processes that influence the morphodynamics of streams that flow through peat bogs. Using field and computer-based methods, I am looking at a small stream in central Minnesota to understand geomorphic processes that are largely different than those of alluvial streams and rivers.

What is Sedimentology?

Sedimentology encompasses the study of modern and ancient depositional systems, to evaluate the transport of sediment and production of stratigraphy. This information has application for evaluating rivers, deltas, coastal, and marine environments.
