Caring, dedicated faculty members
As a student in the Division of Environmental Science, you’ll work with faculty members who are passionate about both teaching and research – and passionate about helping you succeed. Our experienced, dedicated professors have an open-door policy, which means that they’re always available to offer advice, answer your questions and provide you with academic guidance. And because our faculty members believe in getting students out of the classroom, you’ll have plenty of time to work alongside them as you participate in a variety of transformative experiences and research projects.
