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.

Postdocs

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, in a way, summarizes spacial and temporal changes in flow conditions, sediment characteristics, sediment transport, linear and non-linear mechanisms, large and small-scale changes in bed topography, between others processes.

Jason C Sanford, M.S., expected 2014 (Co-supervisor)
Jason is an M.S. Candidate in Geological Sciences at the University of Texas at Austin, where he is currently exploring geopressure history and geomechanics of reservoir-scale sand injections in the Panoche Giant Injection Complex in central California as the second component of his M.S. thesis work. Efforts include mapping of sand injections in the PGIC in order to construct 3-D physical and 2-D geomechanical models of sand injection and understanding and modeling hydraulic fracture initiation and propagation and fluid-sand slurry transport during sand injection. As the first component of his M.S. thesis work, Jason mapped the Cretaceous-Paleogene boundary deposit in the Gulf of Mexico, employing regional seismic, well-log, and core interpretation in order to evaluate the basin's response to the Chicxulub Impact.

Yao You, Ph.D., expected 2013 (Co-supervisor)
I am interested in studying the coupling of geomechanics and geomorphology.
