Heidi Rodenhizer

Dr. Heidi Rodenhizer combines remote sensing and on-the-ground measurements to monitor changes in the Arctic. Her projects track abrupt permafrost thaw, and help establish monitoring sites for permafrost-related carbon emissions. Her research will provide a more precise assessment of the volume of emissions from thawing permafrost which will help inform climate policies and carbon budgets.

Dr. Rodenhizer’s fascination with tundra landscapes started early, after taking a trip to Denali National Park shortly after graduating from high school. While in college, she participated in the Polaris Project and traveled to Siberia for her first taste of permafrost research. Since then, she has enjoyed finding opportunities to use her technical skills to solve environmental problems. Her current work is motivated by the knowledge that the research she does today will contribute to a more sustainable and livable future on Earth.

In her free time, Dr. Rodenhizer enjoys hiking, skiing, biking, climbing, playing fiddle in a local Irish session, and knitting—preferably with her cat on her lap.
