Promoting Geoscience Research, Education & Success

My interests

My research interests include fluvial geomorphology, ecogeomorphology, carbon cycle, water resources management, and coupled natural-human systems. I study rivers and floodplains and how river processes change the earth. My PhD research focused on floodplains along the Yukon River and it’s tributaries in interior Alaska. Specifically, I’m interested in how much carbon is stored in floodplain sediments and wood, and how river processes influences the storage of carbon. For my master’s research at the University of Texas at Austin, I studied floodplains and the hydro-geomorphology of the Araguaia River in central Brazil. My research interests include fluvial geomorphology (the study of rivers and how they change the earth’s surface), floodplains, environmental policy and management, land use change, coupled natural-human systems, and the many aspects of geography. I hope to become a professor at a college or university and teach and conduct research. In my free time, I enjoy spending time with my husband, playing guitar and singing, biking, and outdoor activities.

How I became a scientist

After growing up on a river in rural Minnesota, I became interested in studying rivers while majoring in physical geography and political science at the University of Wisconsin-Madison. After completing my bachelor’s degree, I worked in Washington, DC, first at the National Geographic Society as a research intern and then contract researcher, and then at the Union of Concerned Scientists, a science-based advocacy group. I thought that I would remain in the policy world, but I realized that I wanted to know more about science and the natural world, so I went back for my master’s in geography at the University of Texas. I decided to continue my education by obtaining a PhD in Earth Sciences at Colorado State University. I am still interested in policy, but I would like to conduct science that informs policy and management of natural resources.

How my work benefits society

Understanding the global carbon cycle, or how carbon moves through the land, ocean, and atmosphere and where it is stored, is important for fully understanding climate change and how humans are affecting climate. One aspect of the carbon cycle that isn’t well understood is how much carbon is stored in rivers and floodplains. There may be more carbon in rivers and floodplains than previously thought, which is important for determining the movement of carbon between the land, ocean, and atmosphere. As rivers transport sediment and organic matter, they can deposit those materials in their floodplains, storing carbon. I am quantifying that storage in the boreal (subarctic) zone through research on floodplains in the Yukon Flats National Wildlife Refuge in interior Alaska. My research will inform how geomorphology and hydrology influence carbon dynamics.
