Research into Human-Animal-Environment Relationships
At the Institute for Human-Animal Connection (IHAC), we conduct scientifically rigorous research and scholarship in the areas of trauma, youth development, and animals in communities to improve the overall well-being of humans, animals, and the environment. Informed by a systems view of social problems and guided by principles of efficacy, beneficence, and justice, our research provides novel insights into the relationships between humans, animals, and the environment we share.
Therapeutic Human-Animal Interactions: Youth Development
We are working to understand how youth relationships with other animals and nature create pathways for collective thriving and ecological justice.
- We are identifying how to ethically and most effectively incorporate animals and the natural environment into therapeutic and educational settings to promote thriving among diverse youth.
- We are measuring the impacts of involving therapy dogs in mental health therapy on client engagement and health outcomes.
- In partnership with Denver Public Schools, we’re developing and empirically evaluating an eco-minded professional development curriculum for educators to support youth to contribute to building an equitable and regenerative future for themselves, their communities, and Earth.
- We are identifying facilitators and barriers to youth civic development through participation in ecological justice.
- Some of our collaborators include
- Green Chimneys
- Denver Public Schools
- Center for Sustainability, University of Denver
In our study of humane education, 96% of respondents—829 school social workers, psychologists, teachers and administrators—supported broader incorporation of humane education in U.S. schools.
Therapeutic Human-Animal Interactions: Trauma
IHAC's research team is working to understand how human-animal-environment interactions impact stress and trauma.
- We are identifying best practices for implementing prison-based dog training programs and measuring the impacts of these programs on incarcerated people, prison staff, dogs, and community health.
- We are measuring the impacts of human-canine interactions on both species’ responses to stress using biomarkers and measures of subjective stress.
- We are using surveys and physiological data to explore how pairing military veterans with post-traumatic stress disorder (PTSD) and their service dogs impacts both species’ well-being over time.
- We are documenting indigenous and tribal community members’ perspectives on the impacts of colonization and historical trauma on their relationships with free-roaming dogs.
- We are developing protocols for integrating trauma-informed care principles into research.
- Some of our collaborators include:
- Dr. Michael Yellow Bird, University of Manitoba
- Dr. Aurélie Ledreux, University of Colorado Anschutz
Animals and Communities
We’re working to understand how companion animal welfare challenges intersect with social and ecological justice issues.
- We are partnering with human and companion animal service providers to address interpersonal and structural barriers to accessing veterinary care.
- We are documenting the experiences of families who are seeking pet inclusive affordable housing
- We are exploring how to integrate community engagement strategies into animal control, field services, and humane law enforcement.
- We are measuring the social, environmental, and economic impacts of animal welfare practices and policies.
- Some of our collaborators include:
- The Humane Society of the United States Pets for Life
- National Animal Care and Control Association
There has been a misconception that people in low-income communities or communities of color are opposed to spaying and neutering, but in a recent study, IHAC researchers concluded that race and ethnicity are not primary determinants in use of veterinary services, although access to care is.

New DU Research Measures Impact of Denver's Pit Bull BanSince the ban’s adoption in 1989, the question of public safety has, in large part, shaped the conversation over Denver’s BSL, but a new University of Denver study, published in Animal Law Review by the Institute for Human-Animal Connection (IHAC) at the Graduate School of Social Work (GSSW), calls this argument into question.

Professor's Research Measures Economic Impact of Animal Welfare ActivitiesIssues like rising health care costs and increasing rates of obesity usually fall on the shoulders of doctors, policy makers and government officials. But Oklahoma City’s unlikely superheroes in the arena of human health may just be dogs.
