Molecular basis of inherited diseases in companion animals; developing polymorphic markers for the canine Y chromosomes to understand the relationship between different dog breeds.
Pigmentation biology; hereditary ocular disorders; equine genomics and genetics.
Fertilization and fertility; sperm-oocyte membrane protein interactions, species variation and the effect of toxicants.
My research focus is on the husbandry, behavior, and welfare of small to large scale poultry production. I am particularly interested in understanding the challenges facing small scale and backyard poultry flocks as well as the impacts of housing systems on poultry health and welfare on large scale facilities. I am also interested in developing on farm assessment tools for producers to monitor the health and welfare of their own flocks.
Development of statistical methods and computational algorithms for quantitative and statistical genetics, including genomic prediction and genome-wide association studies. Development of software tools for whole-genome analyses. Statistical models for –omic data.
Biochemistry of sex steroid synthesis, conceptus development, sexual differentiation, comparative reproduction and adrenal function.
Aquatic toxicology and water quality; molecular mechanisms of toxicology.
Avian developmental genetics, embryology, cytogenetics, and genomics.
Reproductive and developmental biology. Paracrine and endocrine regulation of follicle and oocyte development and carry over effects of adverse environments during folliculogenesis on embryonic development. Biology of ovarian oocyte progenitor cells (oogonial stem cells) and their potential to improve and restore female fertility. application of basic concepts of reproductive biology and assisted reproductive techniques to improve animal and human health and efficiency of agriculture worldwide.
Ruminant nutrition of dairy cattle; mammary gland synthesis of milk protein and fat; nutrient digestion, absorption, and metabolism; evaluation of by-product feedstuffs and forage quality.
