  • Associate Scientist
Dr. Anna Liljedahl

Dr. Anna Liljedahl’s work is rooted in a life-long love of water and a deep sense of connection to Alaska’s environment and communities. Her research focuses on how climate change is altering the storage and movement of water in Arctic ecosystems. She has probed the impact of glacial melt and permafrost thawing on natural processes, like ponding and runoff, as well as built infrastructure, including hydropower. Dr. Liljedahl’s work combines field measurements with remote sensing data to produce high-resolution computer models at watershed scales.

Through projects like the Permafrost Discovery Gateway, Dr. Liljedahl strives to expand access to information and to expedite knowledge-generation from big data to serve earth scientists and communities facing climate impacts.

Dr. Liljedahl fell in love with Alaska as an exchange student and currently resides in Homer, Alaska. She draws insight, inspiration, and joy from living in the community and ecosystem she studies. She enjoys local food culture, hiking, and skijoring with her pet husky.

There’s flood insurance, but no insurance for permafrost thaw. People’s houses are literally falling over and sewer pipes breaking. When it comes to climate change, we need some big ideas and out-of-the-box thinking.
