Here you can:
Discover the links
between the health
of people, animals
and the environments
we share.
Harness your passion for improving public health.
At DEOHS, you can:

Evaluate and improve safety practices to protect the health of veterinary workers (the PhD dissertation of Heather Fowler, pictured above)

Investigate how antibiotic-resistant E. coli is ending up in the waste of river otters and other marine mammals.

Collaborate with international partners to detect viruses that can be transmitted from animals to humans.
Why study One Health?
One Health is a transdisciplinary approach to health issues affecting humans, animals and the rapidly changing environments we share. One Health specialists look at a range of issues—from emerging zoonotic diseases and antimicrobial resistance to climate change and food production—through the lens of creating a healthy coexistence between humans and animals in sustainable ecosystems.

As a student in One Health, you will:
- Choose to earn your MS, MS-Applied or PhD degree.
- Take common core courses introducing foundational concepts and skills, including: risk assessment, management and communication; assessment and management of exposures to environmental hazards; core principles of toxicology; and how to use a One Health approach to address complex challenges.
- Learn about the linkages among human, animal and environmental health; how climate change is impacting those connections; and the unique occupational health risks faced by workers who come in contact with animals. You will also choose additional courses on topics that align with your interests, such as antibiotic-resistant bacteria and genes, the microbiome and recognition and control of health and safety hazards in industrial settings.
- Complete a culminating experience (thesis or dissertation) showcasing your ability to integrate the skills you have learned to address an environmental or occupational health problem.

When I was researching graduate schools, the One Health program at UW stood out to me. I’ve been impressed with the support I receive from my mentors and the availability of research funding.

Our faculty and research

One Health has already achieved remarkable progress in the control of zoonotic diseases, but it often prioritizes the life of humans over other living beings and neglects the environmental domain. Now is the time to move One Health forward by addressing these limitations, and broadening One Health to include the political, cultural, social, historical, and economic contexts that shape the health of multispecies collectives.
