Advantages of Domestic Species as Dual-Use Models that Benefit Agricultural and Biomedial Research

I focus on the following four areas of reproduction in cattle:

1. determination of whether anti-Müllerian hormone (ovarian growth factor produced by healthy growing ovarian follicles) is a reliable biomarker to predict future fertility, health and herd longevity of dairy cows;
2. development of new, more efficient superovulation techniques to improve embryo transfer in cattle that may also benefit assisted reproductive technologies (ART) in women,
3. determination of the mechanisms whereby excessive hormonal treatments during superovulation impair embryo survival, and
4. determination of the role of excessive maternal androgen production in cows induced by mild nutrition restriction during the first trimester of pregnancy on health and fertility of their female progeny.

My research is currently funded by AgBioResearch and grants from USDA-NIFA-AFRI and the “dual purpose research program” sponsored by NIH-USDA-NIFA-AFRI.
