Yulia Din is a historian specializing in the history of Sakhalin Koreans and Sakhalin Island. Born in Tbilisi in the Georgian Soviet Socialist Republic, now Georgia, she completed graduate studies in national history at Sakhalin State University. After working at the State Historical Archive of the Sakhalin Region, she became deputy director for academic research at the Sakhalin Regional Museum. In her study published in Japanese as “Saharin Chosenjin Diasupora,” Din traces how Koreans who migrated to Japanese-ruled Karafuto were prevented from returning home after World War II and subsequently confronted questions of nationality, repatriation, and adaptation within Soviet and post-Soviet society. The Korean edition of the book received the Yongjae Emerging Scholar Award in 2024.
