Training and Education in Public Health: Why Now More Than Ever

BU’s Chair of Community Health Sciences, Carlos Rodriguez-Diaz, on why a public health degree offers a path to creating meaningful change.

We are living in a time when a complex interplay of factors, including biology, climate change, political instability, economic inequality, and social polarization, shapes health. Public health is on the front lines of multiple, overlapping crises, including pandemics, mental health, chronic disease, migration, and environmental threats, all of which demand coordinated, local, national, and global responses.

These times represent a reckoning for public health. The COVID-19 pandemic exposed weaknesses in health systems, inequities in care, and the consequences of underinvestment in health. At the same time, it created a transformative moment—an opportunity to rebuild trust, center equity, and reimagine how public health can serve diverse communities. Advances in technology, data science, and genomics are reshaping the field, offering extraordinary tools for surveillance, prevention, and precision health. Yet, misinformation, politicization of health, and unequal access to innovation create new barriers. Public health must strike a balance between innovation and ethics, as well as equity and inclusivity.

Challenging times for everyone’s well-being are when public health is most needed.

Public health is my passion. My experiences are a testament to the power of public health. My education in public health has changed me and my capacity to contribute to a better future for the communities I’ve worked with, as well as to the health of many, for the health of all. As a public health professional and scholar, I am biased. However, after more than two decades in the field, I can confirm that public health education is life-changing and is a path for professional growth, engagement for health, and contributing to a healthier world.

A graduate degree in public health equips professionals with knowledge, skills, and leadership to address today’s most pressing health challenges. Public health is more than addressing populations’ illnesses or injuries; it’s about preventing disease, promoting wellness, and creating healthier, more equitable communities. Through advanced training in epidemiology, health policy, biostatistics, global health, environmental sciences, and community engagement, we learn to analyze complex health problems, design effective interventions, and influence systemic change. This preparation is crucial for addressing pressing issues such as infectious disease outbreaks, chronic illnesses, vaccine rollout, and the impact of climate change on health.

As a scholar, I am proud to see what our students and alumni achieve in the world. Graduates of public health programs are leaders in government, non-profit organizations, academia, healthcare systems, and the private sector. Their work improves lives by shaping policy, strengthening health systems, and ensuring that all people—regardless of background—can achieve their full health potential. A graduate degree in public health is more than a credential. It’s a commitment to creating healthier futures for individuals, families, and communities worldwide.

We are living in a pivotal moment for public health—an era marked by profound challenges and historic opportunities. The crises we face are global, complex, and deeply interconnected. Still, they also open the door to reimagine a future where equity, science, and community are at the heart of health.

To those considering a degree in public health or already working in the field: We need you. Public health opens doors to making a real difference in people’s lives. Don’t lose hope, remain inspired, and let that guide your journey.
