Dr. Bromfield's laboratory focuses on infection and immunity in the female reproductive tract, in particular we have a specific interest in uterine infection in dairy cows. Approximately 40% of all dairy cows acquire a uterine infection following calving resulting in pain, infertility and reduced milk production.
Dr. Samantha Brooks became interested in equine research and obtained a Bachelor of Science degree in Agricultural Biotechnology. She remained at the University of Kentucky to study at the Gluck Equine Research Center. While there she earned her Ph.D. in Veterinary Science, specializing in Equine Genetics.
Chad Carr grew up in Bethpage, TN, 30 miles north of Nashville on a diversified livestock operation which included purebred Hampshire hogs and commercial beef cattle production. Chad received his Bachelor’s and Master’s degrees in Animal Science at Oklahoma State University and his Ph.D. in Animal Science at the University of Missouri
Dr. Dahl conducts applied and basic research with direct impact on animal production and health. Specifically, his program focuses on understanding the physiological impact of management interventions, notably photoperiod and heat stress abatement, at various stages of the lactation cycle, in an attempt to optimize cow health and performance.
Dr. De Vries teaches 2 undergraduate dairy courses and is involved in Dairy Challenge and the U.S. Dairy Education and Training Consortium. His research interests are in the optimization of culling and replacement strategies, statistical process control, economics of reproduction and genetics, and precision dairy farming.
Dr. Nicolas DiLorenzo received his degree in Agricultural Engineering from the Universidad Nacional de La Plata, Argentina. He moved to the U.S. to pursue graduate studies at the University of Minnesota, where he obtained his Master's degree and his PhD in Animal Science with an emphasis in beef cattle nutrition.

Kyle grew up in Modesto California raising swine, cattle, sheep, and chickens on his family farm. He was highly involved with the collegiate meat and livestock judging through his time at Modesto Junior College and Fresno State University where he received his Bachelor's degree in Agricultural Education.
Dr. Nelson holds research and teaching appointments in the Department of Animal Sciences. He specializes in vitamin nutrition and the physiology of cattle. Much of his research focuses on the role of vitamin D in immunity as it applies to the health and productivity of cattle. His teaching interests include sustainable cattle systems, physiology, vitamins, and endocrinology.
The goal of Dr. Scheffler’s research is to optimize muscle growth, composition, and meat quality. In particular, she is interested in how muscle metabolic phenotype and signaling pathways influence nutrient partitioning and growth of skeletal muscle, and their relation to whole body metabolism and health.
Dr. Todd Thrift received his B.S. at the University of Kentucky in Animal Science, an M.S. at Oklahoma State University in Ruminant Nutrition, and a Ph.D. at Texas A&M University in Physiology of Reproduction. Dr. Thrift has been with the University of Florida’s Department of Animal Science in a 70% teaching, 30% extension position in Beef Cattle Management.
Dr. Warren directs the equine nutrition program at the UF. Her research evaluates the effects of nutrition on immune function, athletic performance, and reproduction in horses. She also works on identifying management and nutrition solutions that will minimize the environmental impact of manure on water quality.
The title of emeritus is conferred by colleagues for meritorious service prior to retirement. The Department of Animal Sciences wishes to acknowledge the faculty members who have attained the ongoing privilege in academic convocations. Click on the individual names to send an email.

The Department of Animal Sciences depends upon collaborations with scientists from other organizations throughout the world to achieve its commitments in research, extension and teaching. A select group of scientists are appointed as Sustaining Courtesy Faculty because of a continuous record of service and collaboration with the department.
Dr. Bilby is currently an Associate Director of Cattle Technical Services for Merck Animal Health. He manages a team of dairy-focused veterinarians and PhDs across the US who support the Merck cattle division with technical expertise on a variety of topics. He also specializes in cattle reproduction and provide technical support for both beef and dairy cattle. He obtained the PhD in dairy cattle reproduction from the University of Florida under the direction of Dr. Bill Thatcher. Current interests include cattle reproduction, heat stress, transition cow health and new product development.

John, his wife Misty, and sons Ellery and Henry live in Sun Prairie, Wisconsin with two cats of uncertain parentage.
Dr. Dikmen serves as Professor and Head of the Department of Animal Science in the Faculty of Veterinary Medicine, Bursa Uludağ University in Bursa, Turkey. He received his DVM (1999) and Ph.D. (2004) degrees at that university and has been on the faculty since 2004. His research interests are focused on heat stress management in dairy and beef cattle and the development of improvement strategies for genetic selection of production traits. He spent a one-year sabbatical at the University of Florida in 2007 and returns to the department yearly to conduct collaborative research on the genetic basis for thermotolerance in cattle.
Dr. Ipharraguerre is a Senior Scientist at the Institute of Human Nutrition and Food Science, University of Kiel, Germany. He received a degree in Agricultural Sciences (1996) from the University of Buenos Aires, Argentina, and an M.S. (2001) and Ph.D. (2004) in Animal Sciences focused on nutritional physiology of dairy cows from the University of Illinois, USA. In his current position, he leads research on the impact of diet on the enterohepatic system and the resulting immunometabolic implications for the host, with special emphasis on bile acid metabolism and signaling. He is also deeply interested in developing and expanding the use of Drosophila melanogaster in nutritional research and health.
Dr. Jim Quigley is a researcher, author, speaker, and leader who has helped improve the well-being of young calves for more than 30 years. Dr. Quigley received his B.S. from the University of New Hampshire in 1979 as well as his M.S. in 1983, and he received his Ph.D. from Virginia Tech. in 1985. In the past he has been an Associate Professor at the University of Tennessee, Vice President for Research at Diamond V Mills, and Vice President and Director of Calf Operations at APC, Inc., in Ankeny, Iowa. He is currently Technical Lead for Cargill, Inc. and provides technical support for calf and heifer topics for all Cargill’s business around the world.
Sha Tao is an associate professor in the Department of Animal and Dairy Science at the University of Georgia. A native of Kaifeng, China, Tao obtained the B.S. in Agriculture in 2004 and M.S. in Animal Sciences in 2007 from Henan University of Technology, China. He completed the Ph.D. in Animal Molecular and Cellular Biology at the University of Florida in 2012. Current research is focused on the impact of heat stress on mammary gland development and health in dairy cows, the association among environment, body temperature and behavior of cows in confinement and grazing dairies, and nutritional and management strategies to minimize the negative impacts of heat stress during summer.
Dr. Zenobi serves as Technical Services Manager for Balchem LATAM, is the Director of Continued Education for Dairy Production at the Instituto de Reproducción de Córdoba (Argentina) and has a faculty appointment at the National University of Córdoba. A native of Argentina, Marcos’s passions for cows started early, coming from a family that operates a dairy farm. He studied as an Agricultural Engineer in Argentina, specialized in reproduction, completed the MSc degree at the University of Saskatchewan in animal nutrition, and obtained the PhD in animal sciences from the University of Florida. Marcos describes himself as a dairy production consultant who loves science.
