Appointment:  100% Administration

  1. B.S. in Biology Teaching, Brigham Young University, 1982
  2. M.S. in Zoology, Brigham Young University, 1984
  3. Ph.D. in Entomology, minor in Plant Pathology, Cornell University, 1989

Professional Responsibilities and Research Emphasis:

My current responsibilities are focused on administering the department as department head. My research interests are in the areas of (1) biological control of arthropod pests, (2) interactions of arthropod natural enemies with crop production practices, (3) integrated pest management, (4) sustainable agriculture, and (5) ecology of insect predators and parasitoids.

Courses Taught:
  • Insects and People
  • Biological Control
  • General Entomology
  • Principles of Integrated Pest Management
