Professional Interest: Reproductive Physiology and Endocrinology

My research focuses primarily on reproductive physiology and endocrinology with emphasis on environmental and management factors related to embryonic/fetal mortality with assisted reproductive technologies and deviations in estrous cyclicity. During the past years, my laboratory has organized and performed studies in six distinct areas associated with reduced reproductive efficiency. Current fields of interest include: 1) embryonic/fetal loss associated with elevated uterine prostaglandin F2α, 2) testicular development and manipulation in pre-pubertal bulls, 3) reduced reproductive performance associated with clinical and subclinical mastitis, 4) reproductive alterations observed in both bulls and cows grazing endophyte-infected fescue, 5) nutritional parameters affecting pregnancy rate, and 6) economical methods of estrus synchronization and timed insemination.
