Shaping the Future of Public Health at Yale School of Public Health
At the Yale School of Public Health, we are at the forefront of transforming public health by linking science and society to tackle the most pressing health challenges of our time. As a fully independent school within Yale University, we harness interdisciplinary collaboration, cutting-edge research, and community-driven solutions to create systems-level innovations. Our bold vision—making public health foundational to thriving communities everywhere—drives us to educate the next generation of leaders who are equipped to address global and local health disparities. Through this work, we are advancing public health science, shaping policy, and fostering trust in the health systems of tomorrow. Together, we are not just imagining a healthier future—we are building it.

Community The Yale School of Public Health is known for its close community and collaborative environment. We maintain an ideal faculty-to-student ratio that provides students with many opportunities for mentoring relationships with leading public health experts and practitioners. Formal relationships are forged through academic advising, applied practice planning, and the thesis project. Close working relationships with faculty, as well as with classmates and alumni, form the foundation of a student's career network upon graduation.
Students are also deeply embedded into the fabric of the school’s mission through their work on funded faculty research and interventional work in public health. Many volunteer with student-run organizations such as the HAVEN Free Clinic and the Student Consulting Group, deepening their skills and ties to the greater community.
Education The Yale School of Public Health offers specialization in biostatistics, chronic disease epidemiology, environmental health sciences, epidemiology of microbial diseases, health policy, health management, and social and behavioral sciences. The school offers an 11-month Advanced Professional MPH Program or a hybrid, online and on-campus Executive MPH program for individuals who already have an advanced degree and/or substantial work experience. There is also an accelerated MBA/MPH in addition to several other joint degree programs with other professional schools at Yale.
MPH students from any department may add a secondary academic dimension to their degree by completing the Global Health Concentration, Public Health Modeling Concentration, or Implementation Science Track.
All students are encouraged to take courses throughout the Yale campus in complementary disciplines such as law, environmental studies, social sciences, management, divinity, and more as part of their MPH, MS, or PhD studies.
Research YSPH research spans a wide range of topics, including cancer, HIV/AIDS, LGBTQ+ health, global health, environmental hazards and climate change, infectious and chronic diseases, health policy, and much, much more. Innovative work on personal monitors and e-health, implementation science, modeling, and -omics enhances YSPH’s impact in the field. With more than 16 YSPH-based centers and numerous partnerships across the University, Yale offers a fertile environment for collaboration and developing innovative approaches to improving health and well-being.

Public Health Practice Research and practice are intertwined at the Yale School of Public Health. Since C.-E. A. Winslow, the school's founder, did his first health survey upon arrival in New Haven over 100 years ago, our faculty and students have applied their research in real-world settings to advance efforts in achieving health equity, disease prevention, and wellness. We actively work with partners, both local and global, to improve health through community-engaged research and training, program evaluation, policy analysis, lifestyle interventions, leadership and management capacity building, and more. Through a variety of centers, initiatives, and partnerships, the applied practice experience for the MPH degree, case-based course work, and volunteer opportunities, the School brings together practice and research to train students in the real-world application of public health scholarship, skills, and advocacy.
Shown here: The Community Alliance for Research and Engagement at the Yale School of Public Health has conducted two city-wide surveys to steer health interventions in the city of New Haven.
Belonging The School’s commitment to diversity, equity, and inclusion is demonstrated not only by the values and culture that we foster at YSPH but also through our research, teaching and community engagement focused on reducing health inequalities. Faculty, staff, and students investigate the role of race, ethnicity, gender, sexuality, and other factors in health outcomes. Our alumni and student affinity groups are actively involved in helping to advance YSPH’s diversity initiatives and supporting efforts to recruit and retain a more diverse faculty, staff, and student body. YSPH’s Student Diversity Ambassadors play a key role in organizing activities and events aimed at fostering a culture and environment that not only emphasizes a genuine sense of belonging for all but also creates a deeper understanding of our shared humanity and struggles.

Applied Practice and Internship Experiences Each summer, MPH students travel across the globe for their applied practice experiences. These internship projects expose students to real-world challenges and give them a chance to apply what they have learned in the classroom directly. The Career Management Center and Office of Public Health Practice help students identify their placement and plan their projects to meet their Applied Practice Experience (APE) requirements for graduation.

History Founded in 1915 by Charles-Edward Amory Winslow, the Yale School of Public Health is among the oldest schools of public health in the country. Throughout its history, the School has made many important health contributions in areas including environmental sanitation, polio, and cancer. The school has trained thousands of researchers, practitioners, administrators, and educators and continues to draw upon this rich history and tradition as it evolves to meet the health challenges of the 21st century.

Global Health Global health is public health, and Yale has been committed to working around the world for over 50 years. The Yale Institute for Global Health was launched in 2017 as a university-wide effort to address global health issues and serve as the focal point for research, education, and engagement with global partners to improve the health of individuals and populations worldwide. Students in the YSPH Global Health Concentration are encouraged to develop a broad interdisciplinary approach to their work on the world stage.

Alumni and Networking Opportunities Our 6,900-plus alumni remain an integral part of the YSPH community long after earning their degrees. They share their experiences through career service and recruitment events, mentor job-seeking students, and serve as preceptors for summer internships. Graduates can continue their professional development by engaging the Public Health Career Board, joining Yale School of Public Health Alumnifire networking platform, and attending various networking opportunities like the annual alumni symposium and awards luncheon.

Interdisciplinary Opportunities on the Greater Yale Campus Yale School of Public Health students have a remarkable University at their disposal. With well over 10,000 students, 175,000 living alumni, and 5,500 faculty members, Yale has something to offer every academic interest. The campus is renowned for its beautiful Gothic architecture, theater, concerts, museums, and forums with eminent speakers that further enhance student life.
New Haven Settled in 1638, New Haven is known for its rich history and great food. Home to Noah Webster, Eli Whitney, Samuel Colt, the Amistad trials (with defense led by John Quincy Adams), and Emeline Robert Jones (the first woman to practice dentistry in the U.S.), the city was a hub of activity during the Revolutionary and Civil wars. Today, New Haven is a cultural and entertainment destination. Dining options include the famous Pepe’s and Sally’s pizzerias as well as numerous Zagat-rated restaurants.

Community Service Community service is a shared value not just at the Yale School of Public Health but throughout Yale University at large. With leadership from the Office of Public Health Practice, YSPH is bringing together research strengths and volunteer efforts around five areas of focus: maternal and child health, climate change and health, opioids and substance use, ensuring food security, and public health workforce development.
