Dr. Barragan is originally from Algarrobo, Buenos Aires, Argentina. He completed his DVM in 2010 at the University of La Plata, Argentina. After graduating from vet school, he practiced as a beef cattle veterinarian on feedlot facilities in Argentina before moving to Colorado, where he worked as a veterinarian and researcher on a large organic dairy farm. Afterwards, he pursued graduate training at The Ohio State University, where he obtained his Master and PhD degrees.

Dr. Barragan is involved in extension and outreach activities and field investigations, as well as developing and performing applied research to help dairy producers. His research interests have been related to developing new disease preventive practices to improve cow welfare and fertility and developing better training and management programs for Spanish-speaking farm employees in dairy operations.

Dr. Phil Cardoso

Dr. Phil Cardoso is an associate professor at the University of Illinois at Urbana-Champaign. He received his D.V.M., and M.S. degrees from the Federal University of Rio Grande do Sul in Brazil and his Ph.D. from the University of Illinois. Since 2012, Phil has established a unique program and online presence that seamlessly blends his teaching, extension, and research efforts. Phil's Dairy Science program impact by placing students in applied positions and academia. Phil and his students have published over 80 peer-reviewed manuscripts (original research and invited reviews) and 3 invited book chapters to date. The program builds from questions from dairy producers and focuses on having the dairy cow's diet as a medical prescription for performance, health, and reproduction. That is achieved by understanding the impact of nutrition on metabolism, reproduction, and health in dairy cows, as well as mechanisms of metabolic adaptation to stressors and forage quality.

Dr. Luiz Ferraretto

Dr. Luiz Ferraretto is a Ruminant Nutrition Extension Specialist in the Department of Animal and Dairy Sciences at University of Wisconsin-Madison, and his research interests are applied dairy cattle nutrition and management with emphasis on starch and fiber utilization by dairy cows, forage quality and digestibility, and the development and evaluation of assays for feed and forage analysis.

Dr. Eduardo de Souza Ribeiro

Department of Animal Biosciences, University of Guelph

Dr. Eduardo Ribeiro grew up on a small family farm in southern Brazil and graduated in Veterinary Medicine at the Santa Catarina State University in 2008. In 2009, he moved to Florida to start his graduate studies in the Department of Animal Sciences at the University of Florida, completing a MSc in 2011 and a PhD in 2015. In 2016, Dr. Ribeiro joined the Department of Animal Biosciences at the University of Guelph as an Assistant Professor, and in 2020 he was promoted to Associate Professor. At Guelph, Dr. Ribeiro teaches animal health and animal reproduction to undergraduate and graduate students and leads a research program in reproductive health of dairy cattle. His multidisciplinary research program examines problems related to transition health and fertility of dairy cows at all levels of organization, from herd management to cell biology, and aims to develop novel management solutions that ultimately improve efficiency and sustainability of dairy production.

Dr. Normand St-Pierre

Dr. St-Pierre is Professor Emeritus at The Ohio State University and currently President of the American Dairy Science Association. He grew up in Québec, Canada, and received his Ph.D. degree in Dairy Science from The Ohio State University with minors in statistics and economics. He spent most of his career at Ohio State, where he conducted research and extension programs in farm management, nutrition, and biometrics until his retirement from the university in 2016. Before professionally retiring, Dr. St-Pierre oversaw the R&D and Technical Services department for Perdue AgriBusiness - Animal Nutrition until Fall 2022.
