Focus and Interests
My appointment is 60% extension and outreach with a main emphasis in nutrient/feed management, dairy cattle nutrition, and business management. The rest of my appointment is split between research, teaching and dairy team co-chair. My responsibilities encompass developing educational materials and conducting workshops and conferences for producers and agricultural professionals. I also assist in troubleshooting problems out in the field.
Business Management - program leader - develop educational programs and tools related to income over feed costs and cash flow planning.
