I grew up in the Fraser Valley of British Columbia, Canada, which is nestled right along the US/Canada border. It is a beautiful area, rich in agriculture – berries, dairy production, greenhouses, etc.... but I was involved in none of that! I was a ‘city’ girl who grew up loving animals and dreamed of becoming a veterinarian one day. During my freshman year at the University of British Columbia, if you had told me that my career was going to be focused on studying dairy cow behavior and welfare, I would have thought that you were crazy. I had never even seen a dairy cow in-person until my senior year! Flash forward to present day. I have now spent over 15 years working with the dairy industry and I have loved every moment of it. My career trajectory changed during my senior year of undergraduate study when I took an opportunity to work as summer research intern at the UBC Dairy Education and Research Center. This experience introduced me to a field of study I never knew existed. The best piece of advice I could ever offer is: Never say no to a new experience, you have no idea where it could lead you!


I am extremely passionate about the study of animal behavior and animal welfare. I teach classes in both of these areas, specifically ASCI 410: Applied Animal Welfare and ASCI 340: Animal Welfare and Ethics. In addition to these courses, I frequently instruct ASCI 112 & 101: Principles & Introduction to Animal Science as well as ASCI 479: Current Issues in Animal Science (Senior Project).


Another area that I am passionate about is engaging undergraduate students in research. I regularly run a Research Enterprise class that provides students with opportunities to engage in hands on research at our animal units. To date, my research has focused on dairy cattle behavior, health and management. I am particularly interested in studying feeding, social and resting behaviors and understanding the role that these behaviors play in biological functioning and animal health. I also investigate the impact of dairy management on cow health and behavior. For example, in a recently completed study at the Cal Poly Dairy Unit, we showed that young cows experience less stress when moved into a new group with a familiar partner (aka... the buddy system!) compared to being moved alone. Work such as this could provide dairy producers with new strategies to improve the overall welfare of their animals.
