Office of the Dean


These are extraordinary times, and the Yale School of Public Health (YSPH) is ready to meet the challenges and seize the opportunities to advance social justice and health equity for all with curriculum reform, emphasis on research on systemic racism and health, and application of discoveries to practice.

Our school’s world-renowned infectious disease epidemiologists, modelers, and disease control experts are advising local, state, national, and international governments and agencies on the COVID-19 response. The faculty’s innovation and expertise are on full display as they work to develop novel coronavirus testing assays, methods, and detection devices; equitable vaccine and health care policies, and epidemiologically guided solutions to control the pandemic.

Systemic racism is a centuries-old public health crisis. We are committed to educating and empowering current and future generations of public health professionals with an ethos of social justice and equity across all sectors. Our new U.S. Health Justice Concentration is launching this fall to complement the myriad of school-wide efforts to integrate diversity, equity, and inclusion in all that we do. This multi-disciplinary course of study allows students to analyze and address systems and processes that perpetuate health injustice in the United States, with attention to systemic racism as a key social determinant of disease.

We continue study and action to confront the unprecedented crisis in the warming and environmental degradation of our planet. YSPH was the first to offer an online certificate in Climate

Change and Health through our Yale Center on Climate Change and Health. This fall, the new Climate Change and Health Concentration is available to students of all disciplines and aims to address the shortage of public health professionals with the educational background needed to confront this existential threat.

We are at the forefront of discovery, prevention and, mitigation of disease, injury, disability, and stigma, and we hope you will share our mission toprotect and improve the health of the public.

Public health solutions are inherently interdisciplinary, and Yale University is a laboratory for innovation. A critical component of the YSPH experience is knowing the value of collaboration. Please explore our accessible partnerships across YSPH departments, with Yale’s other extraordinary schools, and within our own 545 students, 180 staff, and 144 full-time faculty. We now extend our academic reach with 12 joint-degree programs in coordination with the other graduate and professional schools at Yale, degree partnership programs with four universities overseas, and emerging distance learning and continuing education opportunities. Our coursework is enriched by our new curriculum designed for the modern public health professional driven by experiential learning.

By harnessing technology and cultivating unique partnerships, we are expanding shared resources and fostering exchanges through our centers and initiatives in innovative social entrepreneurship, global health, mathematical modeling of infectious diseases, child and maternal health, climate change and health, implementation science methods, environmental issues in child health, LGBTQ mental health and stigma, and the humanities and arts in public health, to name a few. Local, regional, and global partnerships ensure YSPH can improve the impact of public health and disease prevention. The school has revitalized its strategic foci in support of cutting-edge research, diversity and inclusion, and equitable public health practice.

Founded in 1915 as one of the original U.S. schools of public health, we have evolved into a highly collaborative, innovative, and student-oriented professional school that continues to foster a vibrant, inclusive environment. Our work is rooted in our core values of discovery, application, and service, and YSPH’s excellence is built upon the collective achievements of our diverse community. Follow us through our website and social media, and welcome to our community!

Towards a healthier and just future,
