Allison Kerwin

Research Associate, Animal Science

My research primarily focuses on the nutrition and management of transition dairy cows. My research involves controlled-research trials at the Cornell University Ruminant Center as well as epidemiological field studies involving dairy farms throughout the northeastern United States.

I provide leadership in the Overton laboratory, ranging from designing studies, statistical analysis, writing publications, and supporting graduate and undergraduate students.
