Alex Ramírez is originally from Guadalajara, Mexico where he lived until he graduated from high school. He obtained a BS degree in Animal Science in 1989 and his DVM degree in 1993 from Iowa State University. He practiced in a rural private clinic primarily as a large animal veterinarian with an emphasis in swine for almost 11 years. He left private practice to pursue his interest in teaching and working with students. In 2004 he obtained his Master’s in Public Health from The University of Iowa. In 2005 he became board certified by the American College of Veterinary Preventive Medicine. He has been working at Iowa State University since 2004. In 2008, he joined the Veterinary Diagnostic and Production Animal Medicine Department in swine production medicine where he currently holds the title of Associate Professor with duties in teaching, research and professional practice. In 2011 he received his PhD in Veterinary Microbiology with emphasis in Preventive Medicine from Iowa State University. He has over 100 peer- and non-peer reviewed written works. He has authored several book chapters and is a coeditor for several books including the 4th edition of the American Associations of Swine Veterinarian’s Swine Disease Manual and the ultimate reference on swine diseases, the 10th edition of Diseases of Swine. hkeita/shutterstock.com
