Trip Leaders

Mentoring the Next Generation of Explorers

Heading up each program is a team of talented, dynamic trip leaders who have extensive experience in the field — and love working with students. With no more than nine students to every leader, we’ll have the freedom to break into small teams and explore your interests.

Below, meet some of our outstanding trip leaders who accompanied students in the field last summer.

After graduating, she spent a year working with Environment America, an environmental advocacy organization. Currently, Alex is pursuing a M.S. degree in Ecology and Evolution, as well as a M.Ed. in Science Education with a focus on urban ecology and the use of technology in science education. Alex works with the university’s Learning Sciences Research Institute, developing science education programs that engage middle school students in investigations of backyard wildlife diversity and behavior using camera traps.
