Interests:

Dr. Sudman's primary interests are in the general areas of vertebrate evolution, systematics, and conservation biology. His major training is in the area of mammalogy but he also works 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 and 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. Finally, he uses the information derived from analysis of the sequence data to reconstruct the historical biogeography of the group under study.


Dr. Sudman's 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, and various localities within Texas. Additional research involves comparative karyology, mophometric analyses, and other genetic techniques such as RFLP analyses.
