Dr. William Dozier
Dr. William Dozier is a Professor in the College of Agriculture Poultry Science Department at Auburn University. His research efforts have focused on defining nutritional needs of broilers and the use of alternative ingredients and exogenous enzymes, which can lower feed costs. Dr. Dozier’s emphasis on broiler research has been practical and application oriented, so as to benefit the broiler industry both here in the USA and abroad. Through his numerous papers on the metabolizable energy and amino acid requirements of broilers, the industry has been able to formulate diets closer to the birds requirement, improving performance and saving considerably in the cost of production. Dr. Dozier has received many honors including National Chicken Council Broiler Research Award in 2013 and the American Feed Industry Association Poultry Nutrition Research Award in 2012. He received his B.S. in Animal and Dairy Science from Auburn University, M.S. in Animal Science from the University of Kentucky-Lexington, and Ph.D. in Poultry Science from Auburn University.

He is internationally recognized for his research on the nutritional requirements of turkeys, perinatal nutrition, and nutritional factors that affect gut health. His teaching expertise is in vitamin and mineral metabolism, and feed formulation and simulations modeling. He is a member of the American Registry of Professional Animal Scientists, Poultry Science Association, Southern Poultry Science Society, and World's Poultry Science Association. Dr. Ferket received his B.S. in Agriculture and M.S. in Poultry Nutrition from the University of Guelph, and Ph.D. in Animal Nutrition from Iowa State University.

His research areas include evaluation of quality of soybean meal and other protein sources; feed technology; processing of feeds and ingredients and biotechnology diets; design of feeds for piglet, pullets, and broiler chicks; and influence of nutrition and management on quality of eggs and meat products. Dr. Mateos was Co-Editor in Chief of Animal Feed Science and Technology until 2014 and has been a member of the Editorial Board of Poultry Science on several occasions. He is also vice-president and founder of FEDNA, the Spanish Association of Animal Nutritionists. Dr. Mateos received his B.S. in Animal Production from Universidad Politécnica de Madrid, D.V.M. from Universidad Complutense of Madrid, Ph.D. in Veterinary Science from Barcelona University and Ph.D. in Animal Nutrition from Iowa State University.

Dr. Michael E. Persia
Dr. Michael E. Persia is an Assistant Professor in the Department of Animal and Poultry Sciences at Virginia Tech. His research is to increase the efficiency of poultry production through the characterization, understanding, and manipulation of bird digestive processes. The three major aims of Dr. Persia’s research are to understand the effects of stress, both disease and heat, on nutrient absorption and utilization; to evaluate the efficient utilization of nutrients in poultry production to minimize environmental impacts; and to research areas within nutrition and poultry management critical to the direct needs of the commercial industry in Virginia. Dr. Persia is a member of Gamma Sigma Delta and previously served as the president of the Southern Poultry Science Society from 2012 to 2013 and is finishing a three-year term on the board of directors of the Poultry Science Association.

Dr. Rosemary L. Walzem
Dr. Rosemary L. Walzem is a Professor in the Department of Poultry Science and a member of the Graduate Faculty of Nutrition at Texas A&M University. Her core research focus in poultry is directed towards understanding lipoprotein structure and biology and bird health. Her past research identified the key structural features that enable yolk-targeting of very low density lipoproteins (VLDLy) in laying hens as well as identification of the transient high density lipoproteins (HDLr) involved in ovarian regression. She identified the similarity in metabolic features in obese breeder hens to those of women with poly cystic ovary syndrome; ultimately identifying changes in lipid metabolism that result in ovarian atresia and cardiac dysfunction in obese hens. New work focuses on dietary features that influence gut health, microbiota acquisition and the role of apolipoprotein A1 in innate immune function and its relationship to HDL functionality. As a comparative nutritionist she works across several species and has answered questions in vitamin deficiency, energy excess, protein and lipid nutrition as well as oxidative stress and phytochemical metabolism and bioactivity. Dr. Walzem received her B.S. in Clinical Dietetics, M.S. in Nutrition, and Ph.D. in Nutritional Biochemistry from the University of California, Davis. She is a registered dietitian (RD), interning at the Sutter Hospitals in Sacramento. She serves as subject expert in Nutrition for the Institute of Food Technologists (IFT) and has been their delegate to the Codex Committee on Nutrition and Foods for Special Dietary Purposes since 2004. She has served on the National Institute on Aging’s Intervention Testing Program access panel since 2001 and several NIH study sections where expertise on the interface between agricultural practices and food quality is required.

Dr. Doug Korver
Dr. Douglas Korver is a professor of Poultry Nutrition at the University of Alberta. He studied agriculture at the University of Saskatchewan and earned a Ph.D. from the University of California Davis. His research in feed ingredients has included a substantial effort in evaluation of feed enzymes (phytase, nonstarch polysaccharide degrading enzymes) to increase the utilization of nutrients contained within the feed. Additionally, his program has been increasingly involved in studies investigating approaches to reduce the use of prophylactic antibiotics in poultry feed. He has been a leader in the use of Quantitative Computed Tomography (QCT) to assess in vivo changes over time in broiler, laying hen and turkey bone mineralization, as well as assessing the effects of feed ingredients on bone mineralization and metabolism. Finally, his research program also investigates the effects of feed ingredients, supplements and novel ingredients on the effect of the inflammatory response on poultry productivity and metabolism.

Dr. Jason Lee
Dr. Jason Lee is an Associate Professor of Poultry Science at Texas A&M University and Holder of Emanuel and Elaine Glockzin Professorship of Poultry Science. He earned a B.S in Poultry Science, M.S in Nutrition, and Ph.D. in Poultry Science, all from Texas A&M University. His research focuses on increasing nutrient utilization, reducing nutrient excretion and environmental impact, and maximizing poultry performance while balancing dietary costs. Specific areas include the use of exogenous enzymes to increased nutrient digestibility (mineral, amino acid, and energy), inclusion of probiotics and prebiotics to improve poultry health as the industry shifts toward antibiotic free production, evaluation of amino acid concentration on product yield, and investigation of mineral source and concentration to improve skeletal development in rapidly growing broilers and laying hens. Jason has served on the Foundation for Food and Agriculture Research Expert Review Panel and chaired the USDA NP 108 Panel 10: Committee on Poultry Production and Processing Review
