What is Agricultural Biology?

Research and Engagement

Our research covers every aspect of plant and ecosystem health. We solve biological problems in natural and managed agricultural systems through our collaborative partnerships, like our K-12 education programs. Our aim is continue to strengthening food security and safety while keeping plants and ecosystems healthy.

Story of Impact

Whitney Cranshaw

Entomology Professor Whitney Cranshaw spent his career making sure he has reserved a seat at the table for all Coloradoans who question the critters in their fields, garages, and backyards. A good deal of phobias are attached to insects—from spiders to miller moths—and Cranshaw delights in educating the public about those insects’ back stories.
