Teaching:

Research Interests:

  • Structural Geology
  • Experimental studies of the rheology of geologic materials
  • Deformation mechanisms in the continental crust
  • Faults and fractures in New York State
  • Deformation mechanisms in partially molten rock and their mechanical behavior
  • Interaction of metamorphism and deformation
    • Transformation of albite to coesite and jadeite during deformation

Student Research:

Junior and senior students interested in conducting research are encouraged to seek out a professor to mentor them. Students interested in learning more about how rocks deform, the structures rocks make, and the ramifications of geologic structures on other aspects of geology can work with Dr. Gleason.  Students may earn credit while conducting research resulting in a presentation at the campus-wide Scholar's Day or even a presentation at a professional meeting away from campus.  On occassion, the research is incorporated into a professional publication.  Some examples of student research follow:
