Peter J. Hansen, University of Florida

Dr. Peter J. Hansen has conducted basic and applied research to formulate new concepts regarding the nature of the interaction between the maternal system and developing embryo. The new understanding generated by his work has been used to develop innovative approaches to improving female fertility and increase resistance of animals to heat stress. His work, detailed in over 330 peer-reviewed publications, has resulted in use of embryo transfer to alleviate maternal infertility caused by heat stress. He has characterized genes that confer thermotolerance in dairy cattle and developed cattle that are genetically resistant to heat stress. His research has pointed the way for development of methods to alter postnatal phenotype through modification of preimplantation development. Studies on colony stimulating factor 2 and the methyl donor choline have revealed how molecules in the reproductive tract can regulate embryonic development to modify postnatal phenotype of the resultant offspring.

Abbigail R. Hines, Auburn University

Abbigail R. Hines is Ph.D. student in ruminant nutrition at Auburn University. She received her B.S. degree in Animal Science and Veterinary Technology in 2019 and her M.S. in Animal Science in 2021, both from Tarleton State University. Abbigail's master's research, under the direction of Dr. Brandon Smith, focused on plant nutrient cycling from manure from steers fed titrated levels of dried distillers grains. At Auburn, Abbigail has continued her work with Dr. Smith, now working toward establishing a baseline for digestibility and forage physiological parameters in common bermudagrass cultivars. Following completion of her doctoral degree, Abbigail plans to join the beef nutrition industry in a technical support specialist role.

Jessica P. Acosta Medellin is a Ph.D. student in the Hans H. Stein Monogastric Nutrition Laboratory at the University of Illinois at Urbana-Champaign. She is a native of Colombia and received her B.S. degree in Animal Science from Universidad Nacional de Colombia after completing an internship in Dr. Stein’s Laboratory at the University of Illinois. During her internship, she conducted research to determine the nutritional value of a new source of corn protein. After obtaining her bachelor’s degree, she enrolled in the master’s program in Nutritional Sciences at the University of Illinois where she conducted research to determine effects of an exogenous xylanase on reproductive performance and digestibility of energy and total dietary fiber in sows. She defended her master’s thesis in 2022 and is now working towards her Ph.D. degree in Dr. Stein Laboratory. Her current research focus is on testing the hypothesis that exogenous carbohydrases increase the utilization of dietary fiber in weanling pigs. Jessica has published three peer-reviewed manuscripts and three abstracts.
