Environmental Science at AU

Students and professor, wearing gloves and holding a bucket, work outside in a lake

Our Masters and undergrad BA and BS programs train students to become effective advocates for the environment. The curriculum consists of rigorous science- and policy-based courses and experiential learning that prepare our students for exciting careers in the environmental field.

At a time when the United States federal government appears indifferent to, or even hostile towards, responsible and forward-looking environmental stewardship, the Department of Environmental Science recommits itself to advancing informed, knowledge-based approaches to confronting local and global environmental concerns.

Announcements

In the Media

Sergio Morales (Environmental Science) and Jennah McDonald (Biology), were part of the SEA Semester voyage that discovered good news regarding coral health in the Phoenix Islands Protected Area (PIPA). Their discovery was featured in the New York Times. Accompanied by 21 other undergraduates, SEA Semester faculty, and researchers from the New England Aquarium and the Woods Hole Oceanographic Institution, Sergio and Jennah gathered data on the health of the islands' coral reef ecosystem in order to recommend policy implementations to the PIPA management office in Kiribati—all while sailing as active crewmembers aboard a tall ship research vessel.

Achievements

Cheldina Jean

Cheldina Jean won the prestigious Udall Scholarship. 38 were awarded out of 384 applicants. Jean is a FUND II UNCF STEM scholar who majors in environmental science and minors in statistics and chemistry. She is passionate about becoming an environmental toxicologist, developing remediation products for environmental clean-ups and improving the quality of life of people in developing countries who are disproportionately affected by environmental degradation.

Avery Williams, MS '21 has won the prestigious The Garden Club of America, 2019 GCA Zone VI Fellowship in Urban Forestry for the project: “Using High-Resolution Satellite Data to Track Phenological Shifts of Urban Vegetation for Individual Tree Scale Analyses.” She will be working on this project with Professor Michael Alonzo and the award comes with a $5000 research stipend.

Jiana Blaha wears scuba gear underwater

Jiana Blaha was selected for the 2019 Academic Achievement Award for Excellence in Undergraduate Research or Creative Work by a Junior! Her research uses stable isotope analysis to determine growth rates of the mangrove trees. She also recently participated in a field expedition to Saipan where she worked with Professors Knee and Kim on understanding sources and pathways of nitrogen pollution entering the ocean.

Reaching Out to Reduce Impact

I hope people see the merit of what we’re doing & are inspired to join the fight

As a Student Sustainability Educator, I like finding out what people are interested in, and then catering to those interests. The environment affects everybody, and it's really our job to show people the way in which it affects them. It helps that people are very receptive at AU, so I don't have a hard time engaging with people.
