Previous graduates of the ERE option have written theses on topics including regional water resource management, sustainable wastewater treatment, renewable and hydrogen energy systems, and watershed restoration. A thesis represents the culminating experience in the graduate program, and allows for detailed, independent exploration of a topic of particular interest to the student. A representative list of past theses in the ERE graduation option is provided below.
