Dissertation: Examination of the Relationships of Megachiroptera and Microchiroptera Based on Mitochondrial and Nuclear Ribosomal DNA Sequences

  • Cell biology
  • Human biology
  • Man and the environment
  • Molecular biology
  • Advanced genetics

I am interested in using molecular data to reconstruct evolutionary relationships of organisms and to investigate species boundaries. Projects on bonneted bats (Eumops), African shrews and Myotis species are underway. I am also interested in community structure and the ecology of bats, especially in Big Bend National Park and the Lower Canyons of the Rio Grande.

Currently, I am looking for motivated students that would like to earn their Master of Science degree in mammalogy/systematics using either field or laboratory techniques (or a combination of both). I enjoy working with mature, responsible students that are interested in developing and conducting a successful project. Although I expect some degree of independence from a graduate student, I am willing to discuss projects, questions, problems at any time.
