Research on nutrient management, particularly phosphorus and nitrogen, is well known. Work has contributed to the current recommendation of phosphorus requirements of dairy cows in the 2001 NRC. Research was selected to feature in the NRI Research Highlights.
Research has been expanded to an international scope, with on-going projects with China on global food security, resulting in research grant receipts from both the US and China, and international travel, seminar, and student exchange opportunities, including 6 Penn students receiving externships during the last three years supported by China (air tickets, room & board, and stipend).
