My primary interests are in the general areas of vertebrate evolution, systematics, and conservation biology. While most of my training is in the area of mammalogy, I also work with avian species. Recent research projects include using mitochondrial DNA (mtDNA) sequence data to reconstruct the phylogenetic histories of various groups of mammals in the order Rodentia, as well as assessing the genetic health of endangered or threatened birds through the use of microsatellite analyses.
Favorite research organisms include members of the squirrel family Sciuridae, pocket gophers (fossorial rodents in the family Geomyidae), and various birds including the Attwater's Prairie Chicken and Black-capped Vireos. General research techniques include isolation of DNA, amplification of specific regions of the DNA via polymerase chain reaction (PCR), nucleotide sequencing, analyses of genetic variation of microsatellite DNA, and using AFLP to examine population genetics of rodents, especially pocket gophers. Information derived from analysis of the sequence data is also used to reconstruct the historical biogeography of the group under study.
My research also entails a large amount of field work to collect research specimens. Recent collection expeditions have included trips to the desert southwest, the mountains of Wyoming and Utah, White Sands National Monument in New Mexico, and various localities within Texas.
