Dr. Aston completed his Ph.D. at Utah State University, where he evaluated factors associated with somatic cell nuclear transfer efficiency and nuclear reprogramming. He was involved in bovine nuclear transfer and was part of the first group to successfully clone an equine species. Following his graduate training, Ki joined the Andrology and IVF team at the University of Utah as a Post Doctoral Fellow and later as a member of the faculty in the Division of Urology. His research team focuses on identifying genetic and epigenetic factors associated with male infertility. He is a lead investigator for the NIH-funded Genetics of Male Infertility Initiative (GEMINI), which will generate exome sequences on 1000 men with idiopathic nonobstructive azoospermia. In addition, his lab is involved in several projects to define the normal sperm epigenome, to identify factors that alter sperm epigenetic profiles and to characterize the impacts of altered sperm epigenetics on offspring phenotype.
