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.
Undergraduate Students
- Eeshita Dastidar - Distribution of the SINE element VES in chiropteran families (Carr Research grant)
- Amy Bishop - Taxonomic affinity of the genus Myopterus based on DNA sequence data
- Lisa Smith - Investigation of DNA sequence errors among multiple cloned PCR products.
- Shirley Hammond - Phylogenetic relationships among cockatoo genera using beta-fibrinogen intron 7 DNA sequence data.
- Sandy Bradstreet - Cytochrome b DNA sequence variation in African shrew species (in collaboration with Robert Baker at Texas Tech University).
- Jennifer Apodaca - Molecular systematics of free-tailed bat genera using beta-fibrinogen DNA sequences.
- Anica Debelica - Food habits of Big Free-tailed bats,Nyctinomops macrotis, in Big Bend National Park.
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), African shrews, and Myotis species are currently 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.
