Arnhold Institute for Global Health

Meet the Team

Prabhjot Singh, Director

Message from the Director, Prabhjot Singh
What is global health? At the Arnhold Institute for Global Health, we are focused on protecting and improving the health and well-being of everyone on the planet. We envision a future where every individual has the same opportunity for health in every community across the world.

The need for more effective health care systems arises in communities around the world—from underserved communities in sub-Saharan Africa, to emerging middle-class communities in South Asia, to the diverse communities of East Harlem.

As the global arm of the Mount Sinai Health System, the Arnhold Institute leads research on the design of more equitable and effective care models, disseminating those models through digital products, training systems, and policy design. In close partnership with the Mount Sinai Department of Health System Design and Global Health, we work to accelerate and scale those models, both domestically and abroad. In addition, as part of the Icahn School of Medicine at Mount Sinai, our faculty prepares the next generation of global health leaders to apply these interdisciplinary tools to problems we cannot yet foresee.

As the Arnhold Institute for Global Health engages communities around the globe, again and again we find examples of places that face the same problems, despite having very little else in common. We have much to learn from these places—and they can benefit by learning from each other.

Yours in partnership for building a healthier world,
