Research Contribution

My area of study, animal welfare, is a matter of widespread concern and plays an increasingly important role in policy and regulatory decisions about food production. I investigate how behavior and physiology of cattle change in response to farming practices that may affect animal welfare, such as painful procedures (e.g., tail docking, disbudding), management decisions (e.g., stocking density), and environmental conditions (e.g., effects of weather and mitigation strategies; comfort of lying and standing surfaces). The results of my work contribute to science-based decisions about animal agriculture.

Research Interests

Animal welfare

I am interested in animals that we raise for food and research in my lab primarly focuses on cattle, both dairy and beef. I am interested in motivated students with long-term career goals connected to food and agriculture.
