One Health
A global leader in veterinary education, Penn Vet engages in interdisciplinary problem-solving to address issues of One Health: the intimate connections among human, animal, and environmental health and welfare. As defined by the World Health Organization, the paradigm of One Health has the power to address complex health challenges, such as zoonotic disease, antimicrobial resistance, food security, and emergency preparedness, which are in many ways exacerbated by climate change.
A Leader in the Field
Penn Vet has engaged faculty and students in One Health research programs, seminar series and developed dual degree and graduate certificates. Furthermore, Penn Vet offers numerous opportunities to collaborate on One Health issues with other world-class schools and centers across the University.

Research
To support One Health interdisciplinary research, Penn Vet’s inaugural One Health in Action (OHiA) faculty team is developing multiple opportunities for investigators to share their work with each other and the public.
- OHiA Seminar Series
- OHiA Summer Journal Club
- One Health Summer Research Fellowship for post-graduate students (in development)
In addition to the One Health Summer Research Fellowship, the University’s Environmental Innovations Initiative is supporting the One Health@Penn Research Community (OHPRC), a group of University-wide faculty and students from diverse scholarly backgrounds committed to identifying One Health-related challenges and opportunities. The OHPRC is developing an initial portfolio of academic activities and programming, and student-led projects, that will explore the challenges raised by long-term shifts in weather patterns due to climate change.
