I am a biology education researcher and plant community ecologist. The central theme of my bioeducation research is measuring the learner-centeredness of undergraduate biology classes. I have investigated students’ understanding of plagiarism and how education affects their decisions; classroom alignment and its relative importance in improving students critical thinking through a semester (as compared to the cognitive level of assessments and learning objectives or the learner-centeredness of the classroom); the mechanisms that make a flipped classroom effective or not; and am working to develop a concept inventory for climate change related to biotic impacts and scale.
The core of my ecological research is grounded in disturbance ecology and community response. I use community analyses to uncover gradients in community structure of vascular plants, lichens, and mosses. I have participated in extensive floristic inventories of vascular plants in central Colorado, and lichens and bryophytes of northwestern Alaska and various parts of Utah. I also use secondary compounds exclusive to lichens to help inform community response and develop biochemical protocols.
