Education / Degree

  Ph.D.,  University of Missouri,  1995

 Research interest (Short)

Primary interests involve the tectonic and climatic geomorphology and active tectonics. Other interests are plate tectonics, structural geology, paleogeography, biogeography, and organic evolution.  Present research involves landscape evolution of the Mississippi Valley and surrounding region, documentation of prehistoric earthquakes in the central US and Central America, and the effects of volcanic hotspots on moving crustal plates.

 Courses taught

Quaternary Geology ESCI 7202

An overview of the processes operating during Quaternary that gave rise to the characteristics of Quaternary geologic materials and Quaternary landforms.  Emphasis is on Quaternary climatic instability and its signature on geologic processes globally.

Tectonics ESCI 7311

Current thinking with respect to movement of the Earth’s lithosphere.  Ideas discussed include: plate motions and the processes driving them; regional deformational styles associated with different types of plate margins; lithospheric stress regimes; and changes in tectonic style through geologic time.

Structural Geology ESCI 3512

Basic principles and analytical methods of structural geology.  The focus of the course is the geometric description of structures and current ideas as to the processes that produce a given structural style.  These topics are addressed at map scale, outcrop scale, and micro-scale.
