Undergraduates play an important role in my research. I usually work with 1-3 undergraduates per year. Funding to support undergraduate research may derive from university fellowships and awards or from grants made for specific research projects (e.g. National Science Foundation, US Department of Agriculture, New Mexico Department of Game and Fish). Students work in a team atmosphere as well as independently to address important theoretical and applied questions. For instance, two current projects on which undergraduates play a key role are studies of bot-fly parasitism of jackrabbits, and laboratory assessments of mechanism for ageing wild lagomorphs. We meet frequently to discuss progress, and I urge the students to present their findings at research conferences, and where appropriate, to publish their work.
