Dr. Candace Lyman is originally from Abilene, Kansas, where she completed both her undergraduate and veterinary training at Kansas State University. After graduation she performed a surgical and ambulatory internship at Ocala Equine Hospital in Ocala, Florida. Lyman then moved to College Station, Texas to work in the Texas A&M Equine Embryo Laboratory. It was during her time in College Station that she became practiced in transvaginal aspiration of both mature and immature oocytes for the purposes of intracytoplasmic sperm injection (ICSI) and nuclear transfer (cloning) in the mare. Lyman continued on to perform a residency in Large Animal Reproduction at the University of Pennsylvania’s New Bolton Center in Kennett Square, Pennsylvania and spent a year in an equine private practice. Soon after, she joined the faculty at Oklahoma State University where she now divides her time between the equine, canine, small ruminant and bovine case loads.
