Ovarian Function and Follicle Development
The research in the Johnson laboratory pertains to both improving women's reproductive health, together with the broader objective of understanding patterns of ovarian function and follicle development among vertebrates whose reproductive strategy consists of producing a limited number of offspring combined with considerable maternal investment (e.g., mammals, birds and a few reptiles).
Applications include the potential for enhancing the reproductive potential of threatened/endangered plus domesticated avian species, particularly broiler breeders in which an aberrant regulation of the follicular hierarchy results in suboptimal egg production.
