Jongmoo Park, M.D., Ph.D., is an Assistant Professor in the Department of Radiation Oncology at Kyungpook National University Chilgok Hospital and the School of Medicine, Kyungpook National University, Republic of Korea. He earned his M.D. and M.S. from the University of Ulsan and his Ph.D. from Kyungpook National University. As a board-certified radiation oncologist, his clinical and research paradigm is dedicated to the continuous optimization of radiotherapy protocols for Breast, Lung, and Rectal cancers, with a particular focus on delivering high-precision, patient-centered care. Professor Park’s academic contributions are fundamentally rooted in three long-standing pillars of expertise. First, he specializes in Post-Mastectomy Radiation Therapy (PMRT) for patients undergoing immediate breast reconstruction. By fostering close interdisciplinary collaboration with plastic surgery teams, his research aims to refine treatment strategies that harmonize rigorous oncological control with superior aesthetic and functional recovery. Second, he focuses on the strategic application of Metastasis-Directed Therapy (MDT) via Stereotactic Body Radiation Therapy (SBRT) for oligometastatic lung cancer. His work investigates the clinical efficacy of precision-guided local control to extend progression-free survival and improve outcomes in advanced disease settings. Finally, he is committed to the management of rectal cancer and the optimization of palliative radiotherapy. By implementing
