Dr. Jung-A Choi's research focuses on cancer diagnosis and the identification of biomarkers for anticancer drugs. She conducts biological research in various fields, including tumour suppressor genes, EMT, cytoskeletal signaling mechanisms, and reactive oxygen species, which are important in the cancer progression process. Her areas of interest include the development of tissue and liquid biopsy-based biomarkers for cancer diagnosis, prognosis, and prediction of response to therapy, as well as genetic alteration after chemoradiation therapy in gynecologic cancers.
