His roles include Postdoctoral Research Associate at WSU Mount Vernon NWREC, Entomology Coordinator for Skagit County Extension, and Weed Scientist focusing on integrated pest management strategies.

Research interests span entomology, horticultural pest control, weed science, and agricultural extension. Dr. Coslor operates the Skagit County Horticultural Pest Control Board, monitoring insect threats and collaborating with Louis Nottingham’s Entomology lab. His work emphasizes sustainable practices like mating disruption for leafrollers and trunk-injected pesticides in fruit crops.

Key contributions include studies on polymeric pesticide delivery systems, neonicotinoid efficacy in blueberries, and trunk injection strategies for pest/disease control in apples.
