Master of Science in Public Health (MSPH)
The Master of Science in Public Health (MSPH) is a professional degree alternative to the Master of Public Health (MPH) degree for students who want more focused skills in a specific field of public health or who lack two years of health-related work experience to begin or advance a career as a public health professional. MSPH programs generally require one academic year of coursework, followed by a field placement. The field placement duration and location vary by department/concentration.

Their Future, in Our Hands
A healthy childhood is essential for lifelong well-being, but urgent problems, like chronic absenteeism, the impact of digital devices on mental health, and exposures to environmental toxins, are threatening U.S. kids’ ability to thrive and flourish into adulthood.
How public health approaches and research can help prevent, minimize, and solve these issues is the focus of the special section of the 2025 Fall/Winter issue of Hopkins Bloomberg Public Health, available online now.
Research Saves Lives
Without research—at Johns Hopkins and at thousands of other universities, medical schools, and research institutions across the nation—scientific breakthroughs suffer, and the lifesaving treatments of tomorrow are at risk.
