Molecular genetics and genomics in eukaryotes- modes of gene regulation, structure and evolution; growth regulation and developmental gene expression programs animals. Genetic improvement in poultry and transgenics. Genetics and biology of pathogenic Candida species.

Current Research Efforts:

Bacterial Chondronecrosis with Osteomyelitis leading to Lameness:  We are investigating the epidemiology and progression of bacterial infections of the growth plate in growing broiler chickens that lead to BCO lameness in chickens.  We use a wire flooring system developed by Dr. Robert Wideman (Department of Poultry Science) to induce lameness, and have demonstrated that the primary bacterial species involved is Staphylococcus agnetis.  We have fully sequenced, annotated, and assembled the genome along with bioinformaticians in the AHPCC and at Oklahoma State.  Our current work is to understand the mode of transmission, and colonization so that effective preventative measures can be employed.  We are collaborating with Drs. Kwon, Dridi, and Koltes (Department of Poultry Science) to understand the role of the gut microbiome and epithelium in susceptibility to BCO lameness.


Genetics of ascites susceptibility in the chicken: We are working with Drs. Nicholas Anthony, and Byung Whi Kong (Department of Poultry Science) on the genetics of ascites (a type of Pulmonary Hypertension Syndrome, PHS) in the chicken.  We used SNP based GWAS to identify chromosomal regions associated with ascites susceptibility.  We are pursuing these regions for identification of the genes responsible for the disease.  This joint project is also developing the chicken as a model for PHS in humans.


Genetic analysis of male fertility in the chicken: With Dr. David P. Froman (Oregon State University), we are using a variety of techniques (GWAS, SNP genotyping, proteomics, primordial germ cell culture) to examine testis developmental gene regulation as well as mapping genetic defects in testicular development in the chicken.  We are pursuing the genetics and epigenetics that are associated with poor sperm mobility, a major determinant of low fertility in broiler breeders.


Molecular genetic analysis of populations for species at risk:  With Dr. Steven Beaupré, we used microsatellite loci to estimate population diversity, gene flow, and multiple paternity, in populations of Crotalus horridus (Timber Rattlesnakes) in the Southeastern United States.  We are also assembling a draft of the rattlesnake genome from NextGen sequence data.  Both of these projects impact conservation plans for wildlife management.


Scorpion genomics: Together with Dr. Tsunemi Yamashita (Arkansas Tech University) we are assembling a draft genome of a scorpion species endemic to the south central United States.  We will be examining genomic structure and diversity of toxin genes.
