Dr. Tracy McCracken has spent her professional career focusing on the interrelationships between humans, livestock and wildlife, particularly in developing nations. After finishing her bachelor's degree in Wildlife Biology at Texas A&M University, she worked in various wildlife conservation projects throughout East Africa and in the South American Andes focusing on integrating local communities surrounding national parks into conservation efforts through education, creation of income generating projects and improved livelihoods. During this time, Dr. McCracken noticed that infectious disease was one of the major factors impacting livelihoods and hindering development in many countries. She then decided to pursue a veterinary degree and enrolled at VA-MD Vet Med with a focus on International Veterinary Medicine. She also completed a Master's of Science in Tropical Veterinary Health at the University of Edinburgh in the UK.

After completing her DVM, Dr. McCracken was recruited by United States Agency for International Development (USAID) for their Global Avian Influenza Team. Based in the USAID Department of Economic Growth, Agriculture and Trade, Dr. McCracken worked closely with the USAID Department of Global Health forging a working relationship between the livestock and public health specialists in the organization. She was also the USAID and USDA liaison for avian influenza and helped to implement joint veterinary training activities and programs between these two organizations.

After USAID, Dr. McCracken moved to Rome, Italy to work with the United Nations Food and Agriculture Organization (FAO) as the Deputy Coordinator for Wildlife Health and Ecology. There she provided technical support to programs and policy initiatives on emerging wildlife, livestock, and zoonotic diseases. She also conducted field research studies to provide insight on the wildlife/livestock disease interface helping to identify risk factors for disease emergence. While at FAO, she led the field implementation of "One Health" training courses involving the joint training of human, livestock and wildlife professionals in both the classroom and field with the aim to improve collaborative responses to cross-cutting health issues.

Now at the CPCVM as the Assistant Director of Education and Training, Dr. McCracken is working to expand teaching, training and advisor programs for veterinary students interested in careers outside the sphere of traditional clinical practice. In her teaching she hopes to inspire students to think more openly about the veterinary profession and its role in society, including the promotion of the "One Health" multidisciplinary approach in addressing health challenges.
