We maintain vigorous M.S. and Ph.D. programs at the University of Oregon and are always looking for enthusiastic students. Below are brief profiles of our faculty members who are engaged in structure or tectonics-related studies.

Rebecca Dorsey
email:rdorsey@uoregon.edu

Research focusses on sedimentation and tectonics, with emphasis on field studies of tectonically active sedimentary basins. Most recently she has been working on basins of active extensional and strike-slip settings in Baja California, Mexico, and southern California, U.S. Becky and co-workers analyse the stratigraphic record of active basins in order to better understand dynamic interactions between subsidence, sediment input from eroding sources, evolution of depositional systems, and active structures that control subsidence and uplift.

John Logan
email: JMLLOGAN@aol.com

Research interests center on experimental rock deformation as a tool to elucidate the mechanical properties of rocks--particularly 1) the chemical influence of pore fluids on mechanical and transport properties of fracture arrays and fault zones, 2) natural and induced fracture propagation, and 3) inelastic behavior at pressures and temperatures appropriate to Crustal deformation. Recent applications include the development of folds, earthquake prediction, induced seismicity, waste disposal, hydrocarbon recovery, and exterior stone cladding of buildings. Geographical areas of study have ranged from China, Japan, to Guatemala, the Netherlands and United Kingdom in addition to the United States.

Marli Miller
email:millerm@uoregon.edu

Research emphasizes the use of small-scale structures to reconstruct the structural and kinematic histories of fault or ductile shear zones. She is especially interested in the transition from brittle to ductile behavior in these zones at meso- to microscopic scales. Most recently, Marli is working on a range of tectonic and fault-related problems in Death Valley, California.

Ray Weldon
email: ray@uoregon.edu

Ray is a structural geologist working on active faults. Current projects include paleoseismology of the San Andreas Fault and the Oregon Basin and Range, neotectonics in Central Asia and Oregon, and regional kinematics of the Western United States, Central, and SE Asia. Ray directs the Neotectonics working group at the University of Oregon.

Geophysics and Active Tectonics
We work closely with seismologists Gene Humphreys and Doug Toomey. Gene works on active continental dynamics and Doug works on active mid-ocean ridge systems.
