Answers in Genesis: believing it. defending it. proclaiming it.

Dr. Thomas Yi was born in Kyungkee, Korea in 1954. For his military service, he joined the military science and technology center as a research engineer. He had been there for 10 years from 1978 to 1988. In August 1988, he came to the US to study at the University of Arizona, and obtained an MS (Master of Science) Degree in Aerospace Engineering. His Ph.D. in Mechanical engineering at the same university was awarded for a thesis entitled "Structural ID Based on Vibration Data for Flexible & Rigid Multi-body System Dynamics." Since then, he was there as a research faculty for a while. In 1996 he moved to a western suburb of Chicago to take a position as a Technical Specialist at the CNH technology center. He has co-authored papers in mainstream journals such as ASME and SAE on the Flexible and Rigid Multi-body System Dynamics.

Dr. Yi has been a Christian since 1973. He has long been interested in the defense of the faith, and become a voting member of the Creation Research Society. To uphold the authority of the Bible, especially Genesis, he has established a ministry of the Korean ACT (Association for Creation Truth) at Chicago in June 1999. Through the ACT ministry he has presented various creation seminars at churches and schools. He also writes and reviews articles for the Korean Newspapers and the Christian Journal.
