Dr. Fraley's research is described as "from bench top to table top," basic neurobiology research that translates to the commercial poultry barn. His expertise is in behavioral endocrinology in which he develops studies to understand how environmental changes alters brain chemistry that ultimately affects feeding and reproduction. Dr. Fraley has developed very close ties with Maple Leaf Farms, Inc. to study how changes in lighting in commercial duck barns affects the development and maintenance of fertility. His research also overlaps considerably with the birds' welfare, as there is a lot of physiological cross-talk between welfare/stress and reproductive systems. Specific projects in his lab investigate the neural mechanisms associated with deep brain photoreceptor activation related to reproductive development, and neuroendocrine pathways associated with the ducks' stress response. Although his research focuses on the Pekin duck, he also has projects working with other poultry species.
