Master of Science in Environmental Science (MSES)

Earn an MSES degree and shape the future of environmental science

With a Master of Science in Environmental Science (MSES) degree from the O’Neill School, you’ll become an environmental professional—mastering the science, along with the analytical and policy skills needed to apply scientific knowledge and lead the way toward solving environmental issues facing our global society. Our MSES program is one of the oldest and largest in the nation.

Add an MPA to your MSES degree

Get more education in less time with a dual degree—combine your MSES with an MPA and earn two master's degrees in less time than it would take to earn each degree separately and become sought after by environmental agencies also seeking policy expertise.
