Education

  • B.S. Entomology Purdue University, West Lafayette, IN. 2003
  • M.S. Entomology: Biological Control Purdue University, West Lafayette, IN. 2006

Research Focus

My research interests are concerned with biological control and how to improve its efficacy. Problems associated with climate change and anthropogenic pollution can affect aspects of biological control against insect pests. I am studying how the main and interactive effects of temperature and selenium impact parasitoid fitness, competition, and heat shock protein expression. I am also interested in the effects of pollutants on top-down and bottom-up processes in tritrophic interactions.
