Research Associate Professor

Dr. Julie Smith received her B.S., D.V.M., and Ph.D. degrees from Cornell University. Originally from the NYC suburbs, she headed off to the ag school at Cornell and never looked back. She is married to a Vermont dairyman and has a tractor-loving son.

Dr. Julie has been with UVM since 2002 and has applied her veterinary background to programs in the areas of herd health, calf and heifer management, and agricultural emergency management.

She has conducted trainings for Extension educators, livestock producers, and community members on the risks posed by a range of animal diseases, whether they already exist in the United States, exist outside of the United States, or pose a risk to both animal and human health. In all cases, she emphasizes the importance of awareness and prevention.

As a veterinarian and spouse of a dairy farmer, Dr. Julie is well aware of the animal health and well-being concerns of dairy animals. She has been guiding undergraduate students in thinking critically about animal welfare (in the required course, ASCI 122) since Fall 2014. Her role in coordinating the educational component of Vermont Breakfast on the Farm since 2015 extends these efforts to a wider audience.

Dr. Julie is currently leading a USDA-funded multi-disciplinary, multi-institutional project, which seeks to understand the human dimensions of protecting food animal health, particularly from new, emerging, or exotic pests or diseases. Her previous research efforts studied the interactions among nutrition, growth, and immune system development in young dairy calves and explored the risk of highly contagious disease spread among Vermont dairy farms.

Current Grant-Funded Projects

A Systems Approach to Securing the New England Milk Supply in the Event of a Foot-and-Mouth Disease Outbreak
This three-year project (2022 – 2025) funded through the tactical sciences program of USDA NIFA aims to enhance the readiness of the dairy industry within the New England milkshed to step up biosecurity to mitigate the impacts of foot-and-mouth disease (FMD) if detected anywhere in the United States. Dr. Smith is the project director.

Predicting Livestock Disease Transmission Dynamics under Alternate Biosecurity Risk Management Interventions and Behavioral Responses of Livestock Producers
This five-year project (2021 – 2026) funded through the ecology and evolution of infectious diseases program of USDA NIFA seeks to better understand and predict the risk of foreign animal disease transmission among U.S. livestock herds. The goal is to identify interventions that improve the alignment of economic incentives, increase the effectiveness of risk communication, and enhance voluntary surveillance of foreign animal disease at minimal cost to taxpayers and livestock producers. Dr. Smith is a co-principal investigator.

2020 NADPRP Secure Food Supply, New England style
This two-year project (2021 – 2023) funded through the 2020 National Animal Disease Preparedness and Response Program continues and extends Secure Milk Supply planning, especially regarding permitting processes, in collaboration with New England state animal health officials, private veterinarians, producers, and other industry stakeholders. See the project website for more information. Dr. Smith is the project director.
