GALS is a free summer science program for high school students to learn science hands-on while backpacking through the wilderness. GALS was created in 2016 by four female PhD students in Biology and Ecology programs at Duke University to increase opportunities for students who identify as female or gender nonconforming, students of color, student from low socioeconomic backgrounds, and other groups underrepresented in fields of STEM (Science, Technology, Engineering, and Math). GALS strives to cultivate a passion for environmental science and stewardship, develop leadership abilities, enhance critical thinking skills, and promote teamwork. The program provides the unique opportunity to gain hands-on experience in science and experiential education while immersed in a supportive community of peers.
