Earn an MSES degree and shape the future of environmental science
Our MSES program is one of the oldest—and largest—in the nation.
Benefit from our interdisciplinary approach
You’ll study at a top-tier research institution with access to an expansive and varied curriculum—earning an integrated, holistic degree from a school with an established, national reputation.
Graduate prepared to lead in the public, nonprofit, or corporate world, pairing big-picture ideas with hands-on experience.
The MSES program
Our MSES program is a professional two-year, 48-credit hour degree program with four components.
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.
