He currently has >250 scientific, peer-reviewed manuscripts in a number of research areas including interactions of nutrition and reproduction, the physiological basis for anovular cows, and hormonal regulation of the ovary. From a practical standpoint, he is probably best known for the development, validation, and modification of timed AI protocols such as Ovsynch and Double-Ovsynch. From a basic perspective, he has provided substantial new insights into the mechanisms involved in the regression of the corpus luteum (CL) and mechanisms involved in the selection of a single dominant follicle in cattle. His current research is focused on three main areas:
1) Understanding and reducing pregnancy loss in lactating dairy cows and recipients of in vitro produced (IVF) and cloned embryos.
2) MeFIRST – Mechanisms of Follicle Initiation, Recruitment, and SelecTion.
3) RePROGRAM – Rethinking Programs in Reproduction to Optimize Gains in Reproduction and Management
