She earned bachelor’s and master’s degrees in mechanical engineering at the Korea Advanced Institute of Science and Technology (KAIST) in Taejŏn in 2001 and 2002, respectively. In 2006 she was working toward a doctorate in biological science at KAIST when she was one of two finalists selected from 36,000 applicants to train in Russia for a flight to the International Space Station (ISS). South Korea paid Russia $20 million to allow a South Korean cosmonaut to accompany the Russian spaceflight. Yi was trained as a backup to computer engineer Ko San. The Russian Federal Space Agency, however, barred Ko from the mission for violations of training protocol after he removed reading materials from a training centre and mailed classified documents to South Korea.
