Julio Giordano

Research Focus

Dr. Giordano is the director of the Dairy Cattle Biology and Management Laboratory at Cornell University and an Associate Director of the Cornell Institute for Digital Agriculture (CIDA). Dr. Giordano’s research focuses on the development, implementation, and evaluation of technology for dairy production systems. The overarching goal of his research program is to integrate concepts of animal biology, farm management, engineering, and data-analytics for enhancing the reproductive performance, health, and profitability of dairy cattle.

Dr. Giordano’s group has pioneered research with dairy cattle reproductive biology and health, precision technologies, automation of management tasks, and development of data-driven solutions for dairy herd management. Specific research projects include:

1. creating, implementing, and evaluating devices for automation of reproductive and health management of cattle;
2. developing novel data-driven reproductive and health management programs based on integrated data; and
3. evaluating the performance of precision technologies for health and reproductive monitoring of cattle in commercial dairy farms.

Ultimately, Dr. Giordano’s research group strives for transforming dairy production systems through a better understanding of cow biology and implementation of technology.
