Andrew Friedland is the Richard and Jane Pearl Professor in Environmental Studies at Dartmouth College and co-author of the Environmental Science for the AP Course, 3e® textbook series. He was the founding chair of the AP® Test Development Committee (College Board®) for Environmental Science. He has a strong interest in high school science education, and in the early years of AP® environmental science he participated in many trainer and teacher workshops. For more than 15 years, Andy has been a guest lecturer at various Advanced Placement® Institutes for Secondary Teachers and in high school APES classrooms. He also served on the College Board AP® Environmental Science Curriculum Development and Assessment Committee. Andy regularly teaches introductory environmental science and energy courses at Dartmouth and has taught courses in forest biogeochemistry, global change, and soil science, as well as study abroad courses in Kenya. He created an online introductory environmental science course that is accessible through edX.org and YouTube. Andy received a BA degree in both biology and environmental studies, and a PhD in earth and environmental science, from the University of Pennsylvania. For almost four decades, he has been investigating the effects of air pollution on the cycling of carbon, nitrogen, and lead in high-elevation forests of New England and the Northeast. During the last decade, he has examined the impact of increased demand for wood as a fuel, and the subsequent effect on carbon stored deep in forest soils. Andy has served on panels for the National Science Foundation, USDA Forest Service, and Science Advisory Board of the Environmental Protection Agency. He has authored or coauthored 80 peer-reviewed publications and one other book, Writing Successful Science Proposals, Third Edition (Yale University Press). In 2015, he was named a Fellow of the American Association for the Advancement of Science. Andy is passionate about saving energy and at his home has installed a 4 kW photovoltaic tracker that follows the sun during the day.
