Doctor Tan Kirin was a Human male native of Corellia who was a renowned figure in medical science by the time of the Cold War with the Sith Empire. A professor at the Corellian Science Academy on his homeworld of Corellia, Kirin delivered a lecture series hosted by the Republic Medical Journal and the Coruscant Institute for Medical Sciences shortly before the Empire invaded Corellia in 3641 BBY. The lectures featured a presentation of a summary of his most recent publication, "Replication of T-5 Progenitor Cells Using Isolated Bacta-Kolto Induction", and a question-and-answer session. During the Battle of Corellia, Kirin requested the help of the Republic Military to destroy the bioweapon smokescreen, which the Empire was manufacturing in the captured factories of Ardus Industries.
