MPH education for the 21st century: design of Columbia University's new public health curriculum.

Because public health challenges are changing rapidly, over the past 3 years, we have turned a critical eye to the master of public health program at the Columbia University Mailman School of Public Health. Under a process dubbed "curriculum renewal," we engaged more than 170 faculty, staff, and students (and hundreds of alumni and employers of our graduates) in an initiative to develop a completely newdesign formaster of public health education that launched in fall 2012. We have described its design and structure and presented some preliminary evaluation data.
