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.

Research Interests

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

Current Projects

  • Molecular systematics of the family Molossidae (free-tailed bats) using nuclear and mitochondrial DNA sequences.
  • Molecular systematics of the bonneted bats (genus Eumops).
  • Use of amplified fragment length polymorphism (AFLP) and microsats to resolve conflict between datasets in Myotis ciliolabrum and Myotis californicus.
  • Using thermal infrared imaging to census Mexican long-nosed bats (Leptonycteris nivalis) in Big Bend National Park.
  • Community structure and the ecology of bats in Big Bend National Park and the Lower Canyons of the Rio Grande.
