Positions

Overview

  • Nancy is an alumna of the University of New Hampshire, with a B.S., M.S., and Ph.D. in Animal and Nutritional Sciences. She grew up on a dairy farm in New York and came to the University of New Hampshire for the Pre-Veterinary program but decide research with dairy cows was more exciting. Nancy is a research professor so has no classes assigned to her to teach, but she does guest lectures for various Animal Science course. Rumen microbiology is the area that Nancy enjoys working in the most, but most of her research has been focused on amino acids and protein nutrition in lactating dairy cows. Nancy perfected a technique to determine the relative bioavailability of rumen protected amino acids supplements, which gives ruminant nutritionists a value to assign to these supplements. This helps ruminant nutritionist come up with the most economical and environmentally friendly diet to feed dairy cows. She is also expanding her research interest into minerals fed to dairy cows and hopes to get back to rumen microbiology with some mycotoxin work.
