Research interests:
Both the basic and applied sciences in the area of reproductive physiology.
Specializing in studying the ovary in domestic farm animals as it relates to agriculture and the production of food. The ovary plays a pivotal role in the reproduction process; it produces ova (eggs) for propagation of the species, and also produces corpora lutea, which maintain pregnancy and determine the length of the estrous cycle. Dr. Redmer's research emphasizes the mechanisms regulating development, function and regression of follicles and corpora lutea. The cellular and molecular approaches used to study these processes will provide valuable information for improving reproductive efficiency in farm animals and fertility in humans. Dr. Redmer also conducts research collaboratively with other scientists in animal embryology, focusing on improved embryo collection, transfer, and cryopreservation methods, as well as in research evaluating vascular growth in healing wounds and myocardium.
