Aaron Norris, Ph.D.

Professional Summary

Grazinglands systems, particularly the livestock and forage interface, are my passion and research focus. Currently, my research program is centered on progressing and facilitating stakeholder adoption of livestock and landscape management regimes in rangeland, pasture, and agronomic production systems. My primary areas of focus are nutritional and health status of livestock, landscape management practices, forage management, and strategic grazing to promote system health and productivity. My aim is to support stakeholder and producer goals through cooperative relationships and involvement in applied research.
