Dr. Brad Daigneault 

Assistant Professor - Reproductive Biology

Dr. Daigneault conducts research to identify reasons for infertility in livestock and humans. His research addresses embryo origins of pregnancy failure with an emphasis on paternal contributions and gene-environment interactions that alter sperm function and embryo development. The laboratory uses assisted reproductive technologies and gene editing strategies in multiple species that includes genomic, epigenomic and translational approaches to improve reproductive efficiency for agriculture and biomedical applications.


  • Research

    Dr. Daigneault’s research program is focused on improving reproductive efficiency in livestock and humans by identifying embryo origins of pregnancy failure. His laboratory conducts basic and translational research to address infertility using large animal models for agriculture and biomedical research. Specific interests are paternal contributions and gene-environment interactions that alter embryo development. Our laboratory incorporates bioassays, cellular, genomic, and molecular techniques to answer important questions related to both male and female infertility. Some approaches include genome editing, assisted reproductive technologies, micromanipulation, and semen evaluation techniques. We investigate genomic, epigenomic, and environmental regulation of preimplantation embryo development in cattle, pigs, and horses with an emphasis on post-ejaculatory sperm exposure to environmental toxicants that result in subtle phenotypes but alter sperm function, fertilization, and embryo development. Research conducted with gametes and embryos also serves to model human embryo development by permitting techniques compatible for gene function studies.

    In addition to our primary research focus, we also use large animal models to study human diseases that intersect with infertility. Ourgoal is to identify therapeutic approaches to relieve infertility in human patients. We also conduct equine reproductive research for industry applications and as models of human infertility.
