I am currently the Director and Eberly Professor, ConocoPhillips School of Geology and Geophysics (60%) and Associate Provost (40%) at the University of Oklahoma.

Teaching

I routinely teach undergraduate Sedimentology and Sedimentary Petrology and Earth Systems of the Southern Plains, an introductory level course. Graduate course I teach include Paleomagnetism, Clastic Facies, as well as a number of seminars. I currently have four graduate students. More information on the courses I teach and my graduate students can be found on my personal webpage.

Research

My research interests are focused on diagenetic problems such as the timing and origin of fluid flow and burial diagenetic events. We are using a paleomagnetic/geochemical approach to date diagenetic events and to investigate the nature of the diagenetic alteration. For example, we recently tested if faults in Scotland such as the Great Glen and Moine were fluid conduits. We were able to document and date a number of fluid flow events and determine their origins (e.g., Blumstein et al., 2005). We are currently testing if fluids moved along specific conduits in the Paleozoic rocks in the Canadian Cordillera as well as determining the timing of the events. Grant Heard (M.S. student) and Jorari Pannalal (post doctoral associate) are investigating the timing and origin of burial diagenetic events in the Woodford Shale in Oklahoma. This work is being done in collaboration with Crawford Elliott at Georgia State University.

I am also working on understanding the origin of remagnetizations in sedimentary rocks. A particular focus has been on investigating the origin of synfolding remagnetizations which is being done in collaboration with Mark Evans at Central Connecticut State University. Matthew Zechmeister, a PhD student, is testing whether stress and internal strain during folding can cause alteration of a magnetization into a syntilting configuration. His preliminary results indicate that the type of fold is factor in controlling the rock magnetic properties as well as the presence of a syntilting remagnetization.

We have also been using paleomagnetic analysis to constrain the timing of impact events and to test the origin of impact breccias. Devin Dennie (Ph.D. student) is working on dating the Sierra Madera impact in Texas. Johari Pannalal is working on using magnetostratigrphy to correlate turbidite sections in Italian Appenines. Recent publications are listed below and details on some current projects can be found on my webpage.

I am also the PI on a project "Diversity in Geosciences: Development of a "Pipeline" for Native American Students at the University of Oklahoma" which is a supported by NSF. The objective of the pipeline is to develop opportunities for Native American students to participate in geoscience-related education and research. The �pipeline� has three components: 1) An education and research enrichment program for 7-12th grade Native American students which integrates indigenous knowledge into the geosciences as well as a research experience for teachers, 2) An introductory undergraduate geoscience course which integrates indigenous knowledge into the geosciences, uses Native American Art as a vehicle of learning, and acknowledges the learning styles of Native American students, and 3) A program to provide research internship opportunities for Native American students.
