My research focusses on evolution of populations in response to anthropogenic stressors, especially climate change, and appropriate management practices to ameliorate negative impacts of environmental perturbation. I have evaluated the role of evolution for biotic response to climate change by predicting evolution using quantitative genetic approaches, imposing evolution through artificial selection in ambient and water-stressed conditions, and preparing a baseline collection of seeds that can be used to study evolution using the resurrection approach for the next 50 years. In addition, I conducted several studies to evaluate the effectiveness and potential risks of assisted migration, a climate change management strategy.

I enjoy camping, hiking, canoeing, botanizing, and birding with my husband, Matt Etterson, daughter, Abby, and son, Zak.
