Professor Choi established the philosophy that psychiatric mental health nursing is a process of fully practicing the nature of caring, which is the essence of nursing. Based on this, she is making persistent efforts to improve nursing expertise and expand the body of knowledge in nursing practice, education, research, and policy related to traumatic stress, community mental health, and simulated education.
