Juan J. Loor is Associate Professor of Animal Sciences and Nutritional Sciences at the University of Illinois.  He earned a BS degree from the University of California, Davis, and MS and PhD degrees from Virginia Tech. Loor’s contributions since joining the University of Illinois have been novel, merging “classical” ruminant nutrition with molecular biology and bioinformatics into the discipline of Cattle Nutrigenomics. This research has centered on nutritional management of the periparturient dairy cow, and the role of maternal and early post-natal nutrition on intramuscular fat development in beef cattle. Since 2006, Loor and his mentees have published over 210 peer-reviewed papers that have received more than 4,000 citations. Loor has trained 20 PhD and 12 MS students, 6 post-doctoral fellows, and served as co-mentor for 25 foreign graduate students. Juan Loor has established a broad research program in Nutrigenomics to benefit the production efficiency and health of cattle.
