Dr. Chang Alexander's research focuses on ways to improve how providers and patients talk in order to enhance understanding of illness, improve health outcomes, and the promotion of effective changes in health behavior. His work concentrates on two predominant areas of communication in health care: end-of-life care for oncology patients and preventive health care in adult and adolescents. In end-of-life care his work focuses on conveying prognosis, deciding on treatment options, delivering bad news, engaging in decision making, exchanging information, discussing preferences for life sustaining treatments, and explaining transitions to palliative care.

In preventive health, Dr. Chang Alexander examines and evaluates the quality of physician counseling about behavior change and weight loss. Dr. Chang Alexander’s work in preventive health also focuses on how physicians talk to their adolescent patients about sex. His work in adolescent sexuality is among the first to examine how physicians are talking with their adolescent patients about sex.
