The geological structure and evolution of Oklahoma and Texas have been the central areas of research interest. Such interests have led to the exploration and development of techniques for studying related issues, including the age, origin and make-up of soils and minerals.

Research Interests

Basement rocks in the central interior of the United States. Evolution of the Ouachita foldbelt. Application of strontium isotopes to the solution of geologic problems. Paleozoic structure and evolution of Oklahoma and Texas.
