  • Applied cattle reproduction, with an emphasis on fertility and management
  • Develop a systematic breeding program for dairy cattle to increase fertility rates and improve reproductive and economic advantages of artificial insemination (AI) on dairy farms
  • Investigate the role of environment, management and diseases on cattle reproduction 
  • Interaction between nutrition and reproduction 
  • Enhancing conception rate by reducing early embryonic loss 
  • Collaborate with UI dairy extension specialist Joe Dalton and reproductive physiologist Tracy Davis to address issues on farms, specifically the direct implications on practical reproductive management
