RESEARCH INTERESTS and PROJECTS
I am interested in insect-plant interactions, and more generally the behavior and evolutionary ecology of insects and their populations. My research currently focuses on the interactions between insects and slickspot peppergrass (Lepidium papilliferum), a rare mustard endemic to southwest Idaho. Research topics include the use of seed introductions to create and augment L. papilliferum populations, seed predation by harvester ants, insect-mediated pollination, habitat associations and population dynamics of Owyhee harvester ants, territoriality in harvester ants, and predator-prey interactions between crab spiders and insect pollinators. I have also conducted studies on the mating system and population genetics of L. papilliferum. The genetics research was in collaboration with Dr. Stephen Novak (Boise State).

GRADUATE (and undergraduate) STUDENT OPPORTUNITIES
I have several ongoing projects that focus on the conservation of slickspot peppergrass, including the role of insects as seed predators and pollinators of this rare mustard. Please contact me for updates on research opportunities and the availability of teaching assistantships.
