The University of Washington Tacoma Environmental Sciences, Biomedical Sciences, Environmental Sustainability, and Mathematics majors host an Environmental Research Symposium, Sciences and Mathematics Undergraduate Research Symposium (SAMURS). This event showcases the capstone research projects of our undergraduate students. The presentations by our undergraduate students, cover a broad range of questions and projects related to the environment, mathematics, sustainability and much more. Projects are conducted in the lab, in the trees, in the mud, in the classroom, at an aquarium, on the water, underwater and on land. Some are original research with a faculty mentor, pushing the boundaries of what is known in their fields. Others participate in internships, where they help community partners further their missions through service. What all these diverse students have in common is the determination and dedication to complete an independent study as part of their undergraduate education. We hope you are inspired and educated by what they have accomplished.
