Rev. Dr. Eliana Ah-Rum Ku serves as an Assistant Professor of Homiletics at the Graduate School of Practical Theology in South Korea and as an Adjunct Professor of Worship and Preaching at the Presbyterian University and Theological Seminary. She also brings her expertise to her pastoral role as an associate pastor at Supsam Presbyterian Church.

Dr. Ku specializes in homiletics and biblical interpretation, with a scholarly focus on the theology of lament and hospitality. Her scholarship addresses these themes through (1) postcolonial feminist and Asian immigrant perspectives, (2) ethical hospitality and epistemic justice, (3) multicultural settings, (4) ecological justice, (5) mental health and trauma, and (6) intertextual and interdisciplinary approaches, integrating Asian philosophies such as Taoism and Confucianism, diaspora literature like Pachinko and Comfort Woman, and the works of visual artists such as Käthe Kollwitz and fashion designer Alexander McQueen.

Recently, Ku shared her insights in Lament-Driven Preaching (Pickwick, 2024) and contributed a chapter titled "Towards an Asian Decolonial Christian Hospitality: Shù (恕), Pachinko, and the Migrant Other" in Practical Theology and Majority World Epistemologies (Routledge, 2024).

Outside her professional life, Ku is a dedicated mother to two teenagers, an avid webtoon reader, and a boundless dreamer—a combination that guarantees no two days are alike.
