Overview
Background
I study aspects of reproductive physiology that impact fertility in cattle, early embryonic development, and precision animal agriculture technologies that can improve animal health and performance. The goal of my research program is to apply research-based knowledge to refine current and develop new bio-technologies that can be readily adopted by cattlemen.
My research program is centered on three focus areas:
- To investigate reproductive physiology and advance reproductive efficiency of beef cattle through the development of reliable bio-technologies that can be quickly implemented;
- To maintain collaborative research that focuses on investigating early embryonic development in cattle;
- To develop reliable, efficient, and profitable management strategies and technologies that can enhance the productivity of beef production systems.

Fields of research
Research impacts
I believe that the development of biotechnologies and systems, which can significantly impact beef production, can only be achieved by combining basic and applied research. Further, I believe there is a critical need for research discoveries to be followed by creating extension outreach programs to spread science-based knowledge to stakeholders and the general public. My program is focused on improving the fertility and reproductive efficiency of beef females by better understanding reproductive physiology, advancing reproductive biotechnologies and developing management strategies for increased reproductive success.
