Dr. Mohrig's research group focuses on the application of sedimentary deposits and transport processes to unraveling the evolutions of terrestrial and submarine landscapes. They study the behavior of topography generated at the interface between a granular material and a moving fluid from very short to very long time and space scales, with particular emphasis on processes controlling channel formation, both on land and in the deep ocean. Research methods used by his group include carefully designed laboratory and natural experiments on sediment-transporting flows, field studies of modern and ancient sediment-dispersal systems, theoretical modeling of evolving granular-bed topography, and the remote sensing of subsurface sedimentary deposits using seismic data.

Mauricio M Perillo
Dr. Perillo's research interests are in the broad topic of Process Sedimentology and Stratigraphy (ProceSS). ProceSS is frame under the Sedimentological Fluid Dynamic (SFD) ''trinity'' (Perillo et al, In Preparation). First introduced by Leeder (1983) as the Geological Fluid Dynamic ''trinity''; the term express all the processes linking flow, sediment transport and bedform development. Fluid, Sediment transport and Bed Morphology,...

Mariel Nelson , Ph.D., expected 2025 (Co-supervisor)
I am a geomorphologist and first-year PhD student in the Department of Geological Sciences co-advised by Dr. David Mohrig (quantitative sedimentology and morphodynamics) and Dr. Tim Goudge (planetary surface processes and remote sensing). I seek a mechanistic understanding of links between landscape process and form. My graduate research uses a drone equipped with lidar sensors to map meander migration of bedrock...

Cole M Speed , Ph.D., expected 2023 (Co-supervisor)
I am a PhD student working in the Quantitative Clastics Laboratory (QCL) at the Bureau of Economic Geology. Broadly, my research interests lie in the sedimentology and stratigraphy of clastic depositional systems. I am currently studying both modern and ancient fluvial deposits, planform channel-belt evolution, and the connection between morphodynamic process and stratigraphic architecture. I utilize fieldwork, time-lapse remote sensing...

Catherine Ross , Ph.D., expected 2022 (Committee Member)
I study punctuated events in Earth's history using field observations, geo/thermochronology, microstructural analysis, and geochemistry. I am broadly interested in how deformation and sedimentation on the seconds to days timescales are expressed in the rock record. My first project involves [bold]dating the Chicxulub target rock[/bold], which is important to advancing the understanding of ejecta and environmental processes. The YucatÓn basement...
