Dr. Laura L. Hernandez

Dr. Laura L. Hernandez is an Associate Professor in the Department of Animal and Dairy Sciences at the University of Wisconsin-Madison. She received her Ph.D. in 2008 from the University of Arizona and completed her Post-Doctoral Fellowship at the University of Cincinnati in 2011. Laura's area of research has focused on how serotonin controls the mammary gland's ability to make milk and various aspects of lactation. Dr. Hernandez combines basic research from the cell to whole-animal level in a variety of mammalian species to broaden the focus on the importance of the mammary gland and its contributions to and regulation of a successful lactation in dairy cattle. The outcomes of her novel research are aimed at understanding how serotonin control the cow's physiology while lactating, particularly during the transition period when cows are the most metabolically and physiologically challenged. She specifically focuses on the interaction of serotonin and calcium metabolism during the transition period and how we can better manage calcium around the time of calving to optimize cow health and production. Her research has determined that serotonin is an important regulator of mammary gland and maternal calcium homeostasis during lactation.
