Research
Current Students

1. Systematics of the genus Neotoma
- historical phylogeography of the various species groups
- elucidation of evolutionary relationships among extinct forms using “ancient” DNA.
- use of morphological characters to redefine species lines.

2. Conservation genetics of native Galapagos rodents (genus Nesoryzomys).
- collaboration with Dr. Robert C. Dowler (Angelo State University)

3. Historic and current patterns of gene flow among island populations (Galapagos Islands, Ecuador) of Rattus rattus , R. norvegicus, and Mus musculus.

4. Metacommunity structure of desert rodents: environmentally induced temporal dynamics and a molecular assessment of dispersal effects.
- collaboration with Dr. Richard Stevens ( Louisiana State University)

4. Carnivores of northern Virginia: community structure, movement patterns, and conservation concerns.

5. Genetic variation among members of the Craugastor (Eleutherodactylus) podiciferus species complex (Cerro Utyum robber frog).

6. Confirmation of Wild Tundra and Trumpeter Swan Hybrid Populations in Alaska.
- collaboration with Dr. Pat Gillevet (George Mason University)
