Koal ir-Iuruth

Kaol ir-Iuruth is the Chief Medical Officer aboard the U.S.S. Enterprise-H as part of the Frontiers Accords and the stipulation to have a Romulan delegation stationed aboard the Enterprise and the Frontier. He is from the city of Iuruth, and apparently was involved in a romantic relationship with Salea at some point prior to their serving together on the Enterprise. Kaol was successful in discovering the true nature of the Section 31 genetic "plague" on Credalis IV in 2419. He was also present during the Telaron radiation incident on the Orion homeworld later that same year.

Kaol does not hold a Starfleet commission, and therefore does not wear a Starfleet uniform. His rank is Centurion, which is roughly equal to Lieutenant Commander in Starfleet. Due to his apparent nondescript family lineage, he is unlikely to rise above this grade.
