Biography

Annika joined the Wyoming unit in 2011. Prior to that Annika was a post-doctoral researcher at the Northwest Fisheries Science Center and at the University of Washington in Seattle. She has a BA in ecology and evolutionary biology from Princeton University and a MS and PhD in ecology and evolutionary biology from Yale University. Annika's research has focused on aquatic ecosystems and how these ecosystems are altered by natural and anthropogenic disturbance.

Teaching Interest

Annika currently teaches advanced fisheries management and seminars on topics of interest at University of Wyoming.

Research Interest

Annika is interested in the resistance and resilience of aquatic communities to disturbance. Her research addresses disturbances that are relevant to the conservation and management of aquatic ecosystems through a combination of field observation, experimentation, and modeling. Disturbances of interest include flow alteration, climate change, nutrient loading, invasive species, and energy development. Most of her research involves fish that are of conservation concern and is set in a management context.
