My training, experience, and interests are in the fields of science education and ecology. I hold a Ph.D. in Ecology from Colorado State University. My dissertation focused on the indirect effects of bubonic plague in prairie dogs on plant communities and ecosystem function in Colorado. I received additional experience and training in science education through a post-doctoral position at Michigan State University and a position in exhibit development at the Smithsonian National Museum of Natural History. I was hired at UC Denver in 2008 primarily as a biology education researcher, and the majority of my current work is in that field. However, I also conduct research in ecology because it informs my teaching and my science education research, much of which focuses on student understanding of content related to ecology. I am pleased to be part of a growing national cadre of “science faculty with education specialties” and plan to continue to pursue both lines of research throughout my career.
My science education research interests are concerned with assessing and improving how students understand biological concepts and apply scientific principles, especially concepts and principles related to ecology. I work at both the undergraduate and grades 6-12 levels. My approach to this research employs both quantitative and qualitative data collection and analysis methods. I enjoy working on large-scale, multi-faceted collaborative projects that seek to answer transformative and often complicated research questions. Thus, some of the projects I work on involve many collaborators from across the country. My goals as a science education researcher are to make discoveries that can be used for improving pedagogy and assessment in undergraduate biology education and for informing the development of national science standards and practices for K-12 education. My current research questions are:
What is the current state of environmental literacy in our nation and how can learning progressions be developed and used to support grades 6-12 environmental literacy?
How can we assess and improve undergraduate students’ use of principle-based reasoning about the carbon cycle in introductory biology and ecology courses?
How can data-rich curricula improve undergraduate data literacy and ecological literacy?
My ecological research bridges community and ecosystem ecology to explore how plant communities and soils respond to external factors such as intensive herbivory, nutrient inputs, emerging infectious diseases, and climate change. The model system that I work on has shaped and integrated the questions that I pursue. I study both urban and rural black-tailed prairie dog (Cynomys ludovicianus) communities. Prairie dogs have been historically important influences on the ecology of the Great Plains of the United States and have had considerable effects on the cattle ranching industry over the last century. The role of prairie dogs in the West has changed over the past 70 years with the introduction of bubonic plague and with increasing urbanization of prairie dog habitat. I investigate issues that have management or conservation importance in addition to theoretical and conceptual importance. My field research involves mostly observational studies across space and time gradients. I conduct greenhouse experiments to further explore the mechanisms underlying the broad patterns I observe in the field. Much of my research is situated in and around urban Denver, making it easily accessible to UC Denver student researchers. The research questions currently my focus are:
Do global change factors (urbanization, extended growing season length, increased nitrogen deposition, and introduction of non-native plants) interact with prairie dog grazing to result in novel plant communities that lead to ecosystem transformation?
How does introduced bubonic plague in prairie dogs influence plant communities and ecosystem processes?
