Peter Flemings
Peter Flemings: Director of GeoFluids Consortium, Dr. Flemings specializes in stratigraphy and flow through porous media. He uses seismic, well, and core data to characterize subsurface systems, and he uses theorectical modeling to study stratigraphic and hydrodynamic evolution.
 
 
 
John Germaine
John Germaine: John “Jack” Germaine is a Senior Research Scientist at the Massachussetts Institute of Technology. He is a world leader in experimental methods in geotechnical analysis.
In recent years Jack has worked on small-strain nonlinearity of normally consolidated clay and has explored factors affecting the initial stiffness of cohesive soils.
 
 
 
Ruarri Day-Stirrat
Ruarri Day-Stirrat: Research Associate at the Bureau of Economic Geology. He gained his Ph.D. from Newcastle University, UK, in 2006. Dr. Day-Stirrat is interested in mudstone diagenesis, fabric anisotropy and physical properties. He uses a variety of X-ray and electron beam techniques to better understand the evolution of mudstones from sedimentation into consolidated, diagenetically mature, lithified rocks. He has experience of working with diverse mudstone lithologies from the Tertiary of the Gulf of Mexico to the Mississippian Barnett Shale.
 
     
Derek Sayer
Maria-Katarina Nikolinakou, Postdoc.:
Maria-Katerina Nikolinakou: Postdoctoral Associate at the Bureau of Economic Geology and the Institute of Geophysics, Maria is a Civil/Geotechnical Engineer. She earned her ScD from MIT in 2008, her MSc from MIT and her Diploma from NTUA, Greece. She specializes in theoretical soil mechanics and the constitutive modeling of earth materials. She is interested in understanding the stress state within and around salt bodies. Before joining the Bureau, Maria worked as a postdoc for Shell in the Depleted Drilling Group.

 
     
Derek Sayer
Gang Luo, Postdoc.:
Postdoc fellow at Bureau of Economic Geology. Gang Luo earned his Ph.D. in geosciences from University of Missouri-Columbia, in 2009, his M.S. and B.S. in geophysics and geology from Peking University, P.R. China. His primary research interest is computational geodynamics and finite element modeling on stress within and around salt, fluid flow, fault interactions, earthquake stress triggering, crustal/lithospheric stress and strain evolution during earthquake cycles.

 
     
Mark Andrews  Mark Andrews: Mark's work centers around bringing the Jackson School of Geosciences new GeoMechanics lab on line. Areas of experience include machining small parts, handling electronics, and constructing lab equipment. He designs and builds many of the experimental devices used in the GeoMechanics Lab. Outside of work, Mark's interests include rock and mineral collecting, and seismology.  
     


Current Students
     
Derek Sayer
Derek Sawyer, Ph.D.: Derek is a Ph.D. candidate who studies sedimentation, deformation, and fluid flow on continental margins. His study area is the Mars-Ursa region outboard of the Mississippi River on the upper Mississippi Fan, Gulf of Mexico. Rapid Pleistocene sedimentation of a sand-rich basin-floor fan, two channel-levee systems, and numerous submarine landslides created a fascinating hydrodynamic system. He participated on Integrated Ocean Drilling Program Expedition 308 as a shipboard sedimentologist and has had summer internships at BP and Shell as a graduate student. He earned his M.S. in 2006 from Penn State University in geosciences, advised by Peter Flemings. He earned a B.S. in 2002 in marine science from Eckerd College, St. Petersburg, Florida.
 
 
 
Julia Schneider
Julia Schneider, Ph.D.: Julia is a Ph.D. candidate from Germany who joined the GeoFluidsIII group in Fall 2006. Her interests are in mudrock consolidation, overpressure generation and evolution, and basin-scale fluid flow in deepwater petroleum fields in the Gulf of Mexico, offshore Texas and Louisiana. As part of the UT Geofluids group, Julia is currently involved in geotechnical laboratory experiments, that she performs in the research group’s GeoMechanics Lab, to analyze material properties and fabric of mudrocks. Julia earned a B.S. and M.S. in Geosciences from the University of Bremen in 2004 and 2006, respectively. She participated in expeditions M54/2 in 2002 and ARK XX/3 in 2004, sailed on IODP Expedition 308 in the summer of 2005, and completed an internship with Shell’s Fundamental Rock Properties group in 2007.
 
 
 
Hilary Strong
Hilary Strong, M.S..: Hilary joined the GeoFluids III group in Fall 2007. Her thesis focuses on consolidation characteristics of mass transport complexes in the Ursa Region. Hilary has a BS in geology from UCLA and became interested in slope failure and sediment consolidation while working at a Geotechnical Engineering firm her last year in Los Angeles. Upon completion of her MS, she will join ExxonMobil as an Operations Geologist.
 
 
 
Yao You
Yao You, Ph.D.: Yao joined the group in fall, 2009. He is now working with Dr. Peter Flemings and Dr. David Mohrig in Jackson School of Geosciences. His interests are in quantitative modeling of crustal fluids and geomorphology. He is currently studying failure in sand caused by breaching in subaqueous and submarine environments, and he is also trying to model the pore pressure in Ursa Basin using soil properties measured by the GeoFluids group. Yao earned his B.S. from Peking University in China and he majored geology and mathematics. He then got his Master's degree in Indiana University where he worked with Dr. Mark Person on pore pressure in compacting basins and fluid flow in faults.
