Have you asked yourself why animals with similar genetic potential, managed under the same conditions, perform better than others? Why do heifers under the same developmental program get pregnant while others fail? How do nutrition and genetics play a role in animal development and performance?

To answer these and other questions, our research program lies in understanding the regulatory mechanisms of complex traits in livestock species through the lens of genomics. We are particularly interested in applying genomics, functional genomics, and systems biology methods to gain insights into the genomic basis of economically important traits. Based on these tools, we investigate the molecular mechanisms that underlie beef cattle fertility, the role of nutrition in fetal programming, and the long-term effects on animal performance. Our long-term goal is to deliver molecular targets to improve animal selection and increase the efficiency and sustainability of cow-calf production systems.

Are you curious to know the answers to the above questions as well? Please contact me, and we can discuss the undergraduate or graduate research opportunities in our team.
