Dr. Manjarín is an Assistant Professor in the Animal Science Department. He is originally from Spain, where he earned his DVM degree at University of León. After working for a couple of years in a Small Animal Practice and in a Swine Artificial Insemination Center in Italy and Spain, and as Meat Inspector in England, he moved to East Lansing, MI, where he obtained a MS and PhD degrees in Animal Science at Michigan State University. He completed a second PhD in Veterinary Medicine at University of León, and then moved back to the US to pursue two consecutive Postdoctoral Fellowships at UC Davis, CA, and USDA/ARS Children's Nutrition Research Center, TX, before joining the Cal Poly team. 

Dr. Manjarín research program focuses on identifying the mechanisms by which nutrients regulate lactation and muscle growth, to improve both livestock production and human health. In addition, Dr. Manjarin is leading an International project to introduce the Spanish Iberian Pig breed in Cal Poly, where animals will be raised in a novel free-range setting using pasture and acorns.
