BSES success stories


Ashlyn Carter, BSES’18
Law Student, IU McKinney School of Law, Indianapolis

“I was inspired to apply to law school after listening to my O’Neill School professors speak passionately about the environment. My undergraduate environmental science degree was so rigorous that the academic skills I learned have been invaluable in law school—and helped me balance life in general. Keep an open mind; this degree can take you places you did not plan.”

Corben Andrews, O’Neill Student
2020 Sustainability Scholar

“I feel like the opportunities I’ve had have given me a taste for what it is like to really work in the field of sustainability.”

Required coursework

The BSES is a joint degree program between the O’Neill School of Public and Environmental Affairs and the College of Arts + Sciences—to offer you a selection of courses on a wide range of environmental topics, taught by over 40 faculty and instructors across Indiana University.

You’ll follow an interdisciplinary approach, gaining knowledge and tools from the traditional sciences, such as biology, chemistry, geology, hydrology, mathematics, meteorology, and physics. Many of the courses include field and laboratory work, providing valuable hands-on experience, and demonstrating the applied nature of environmental science. At the same time, you will be encouraged to think broadly about the relationships between science, policy, and management.

As a student in the O'Neill School, you will complete your degree requirements based on your matriculation date – the date you entered Indiana University Bloomington.
