Education

  • Seeking Ph.D., Entomology, University of Kentucky, Lexington, KY (Expected April 2013).
  • B.S., Integrated Biology, Brigham Young University, Provo, Utah (May 2008).

 

Research Interests

My academic interests involve the foraging ecology of arthropod predators and the dynamics of arthropod predator communities. My current research addresses the selection of foraging sites by web-building spiders: the cues used by spiders during the site-selection process, and the implications of web-placement decisions by spiders for their trophic ecology---including potential utility in conservation biological control programs---and for their interactions with other animals in the community. I am also interested in the dynamics of spider populations, including phenology, natural history and dispersal.
