Research Interests

Dr. Horgan’s research interests focus on the fate and transport of pesticides and nutrients, water conservation strategies, and low-input turfgrass systems. Horgan's most recent award recognizing excellence in the turfgrass industry was the prestigious Minnesota Golf Course Superintendents Association President's Award. He is past chair of the National Turfgrass Evaluation Program advisory committee, science editor for Turf News, and past chair of the Turfgrass Science division of the Crop Science Society. In addition to his participation in various state and regional turf conferences within the United States, Horgan has taught soil fertility and plant nutrition in Sweden, Norway, Turkey, Hong Kong, China, and New Zealand. He has taught for the GCSAA since 2006.

In addition, Dr. Horgan outreaches to the community as a Turfgrass Extension Specialist. The position gives him opportunity to interact with the industry and facilitate educational programs designed to meet the needs of the state. He is a faculty advisor to the student chapter of the Golf Course Superintendents Association of America (also known as Turf Club).
