Academic Bio

Ki Aston completed his Ph.D. at Utah State University in 2007. For his dissertation research 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. Upon completion of his graduate training, Ki joined the Andrology team at the University of Utah as a Post Doctoral Fellow in 2007, and in 2011 he received a faculty appointment with the Division of Urology. His research efforts here have focused on identifying genetic and epigenetic factors associated with male infertility. In addition, Ki is actively involved in expanding fertility preservation options at the University of Utah. In his free time, Ki loves spending time with his wife and four young children and enjoys almost any form of outdoor recreation.
