Environmental Natural Science

Overview


Liz Kalies is the Lead Renewable Energy Scientist for the North America region of The Nature Conservancy (TNC), and an adjunct associate professor at the Nicholas School of the Environment at Duke University. She is a terrestrial ecologist, with expertise in wildlife field ecology, restoration, and quantitative ecology. At TNC, she develops sound science to support the clean energy transition, particularly focused on renewable energy siting and design practices. She won the NC Sustainable Energy Association's Clean Energy Innovator of the Year Award in 2019 for her efforts to develop best management practices for wildlife conservation at solar facilities. She has a PhD in wildlife ecology from Northern Arizona University, a master’s degree in ecology from Yale University, and a BS in biology from Cornell University.
