M. Robert Hamersley, PhD
I teach courses on the three most important environmental issues affecting humanity: climate change, water resources, and agriculture. In my classes, students combine perspectives from the sciences, environmental policy, and technology to approach solutions to these problems. In class, students often work in teams to solve problems based on real-life case studies. Students also learn how to write reviews of the scientific literature on these topics. In these courses, students learn to conduct scientific research, go on field trips to nearby county and municipal environmental facilities and natural areas, or learn to grow vegetables on their own plots in the Soka Instructional Garden.
In my research laboratory, highly motivated students can make a contribution to original scientific research studying the production of methane, a powerful greenhouse gas, from wetlands. Work by my students has resulted in 13 presentations at regional and international conferences, as well as published and in-progress manuscripts in scientific journals.
I also play a role in promoting sustainability on campus in my role as a Faculty Representative on the Campus Sustainability Committee and as a mentor to students conducting research on sustainability at SUA. My students’ reports, written as a result of research in Learning Clusters, Independent Study courses, and Capstones, have contributed to SUA being certified at the Silver level through the STARS certification program. Students have conducted water and waste audits conducted biodiversity research and made plans for improving sustainability engagement on campus.
