Areas of Expertise

  • Entomology & Nematology
  • Insect-Plant Interactions
  • Behavioral Ecology
  • Chemical Ecology
  • Multi-trophic Interactions


  • Postdoctoral Fellow - Cornell University (2013), Ecol. & Evol. Biology
  • PhD - University of Florida (2011), Entomology & Nematology
  • MSc - University of Delaware (2008), Entomology & Applied Ecology

My focus is on the behavior and chemical ecology of mutli-trophic interactions. This includes plant responses to belowground herbivory, nematode and insect community ecology, chemical ecology, and coevolution. Research projects include trophic cascades, above-belowground interactions, chemotaxis of soil nematodes, and the evolution of plant defense strategies.
