	Curator of Mammals, Natural Science Research Laboratory, Museum of TTU
	Professor, Mammalian Systematics and Molecular Evolution, Department of Biological Sciences, Texas Tech University

Ph.D., Texas Tech University, 1991 M.S., Texas A&M University, 1986 B.S., Texas A&M University, 1983

Current Research:

	Systematics and molecular evolution in mammals, particularly in geomyoid and simodontine rodents. Examination of hybrid zones between genetically distinct taxa; including isolating mechanisms and the dynamics of genetic introgression. Determining the origin of hybrizymes generated from hybridization events. Chromosomal evolution and how changes in chromosome structure relate to models and mechanisms of speciation. Rapidly evolving DNA sequences and their cause and effect on chromosomal evolution and the organization of these sequences in the mammalian genome. Examination of the origin and evolution of rodent-borne viruses; especially in the use of rodent phylogenies and genetic structure to predict the transmission and evolution of the virus. Epidemiology and zoonoses of mammalian-borne viruses. Growth and utilization of natural history collections, especially those pertaining to mammals. Development of bioinformatics and how this field can better be interphased with natural history collections. Natural history and distributions of mammalian species.
