Specialties: Vegetable production

EDUCATION

Doctor of Philosophy: Cornell University, Ithaca, NY. Department of Fruit and Vegetable Science. Plant Physiology and Agronomy minors. 1992.
Master of Science: Michigan State University, East Lansing, MI. Department of Horticulture. Agronomy minor. 1983.
Bachelor of Science: Michigan State University, East Lansing, MI. Agricultural Education. 1980.

TEACHING

PlSc 4400, Modern Vegetable Production (3 credits; Fall Semester). A course that focuses on the theory and practice relevant to vegetable physiology and production in the context of US and world agricultural systems.

PSB 2800, Fundamentals of Organic Agriculture (3 credits; Spring Semester). This course will introduce students to the history, definitions, requirements, and transitioning of thoughts and farms to organic crop production. Examples from soils, pest management, animal science, field crops, and horticulture will be used to introduce students to the principles behind organic agriculture in the US and world.

EXTENSION

Responsible for outreach efforts to vegetable growers across Utah. Significant work is done to help Utah's farmers and ranchers become more sustainable. These are accomplished through:

  • Conducting applied research on a variety of vegetable crops
  • Coordinating yearly workshops, field days, and educational events for farmers, ranchers and extension personnel
  • Publishing newsletters, research reports, and extension publications
  • Participating in commodity group meetings at the regional, national and international level
