My work is rooted in a life-long appreciation of water and connection to cold region environments and communities. My research focuses on the storage and movement of water in Arctic landscapes including the role of glacial melt and permafrost thawing on watershed hydrology.

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

I fell in love with Alaska as an exchange student and currently reside in Homer, Alaska. I draw insight, inspiration, and joy from living in the community and ecosystem I study. I enjoy local food culture, hiking, and skijoring with my pet husky.

There’s flood insurance, but no insurance for permafrost thaw. People’s houses are literally falling over and sewer pipes are breaking. I want to empower people with useful and accessible data that can support action and solutions.
