Graduate Education
Ph.D. University of Texas, Department of Zoology, 1998

Research Interests:
I have broad interests in insect ecology, evolution, genetics and behavior including:

  • Migration and movement
  • Population genetics
  • Functional genomics
  • Phenotypic plasticity
  • Nutritional ecology
  • Collective behavior
  • Plant-insect-predator interactions
  • Plant-fungus-insect interactions
  • Insect management

My research is multidisciplinary and incorporates approaches ranging from molecular biology to landscape ecology. My recent appointment as the Charles R. Parencia Chair in Cotton Entomology provides me with an exciting and challenging opportunity to further diversify my research program to include insects in cotton agroecosystems.
