doctor Use Dr. in the first reference as a formal title before the name of an individual who holds a doctor of medicine or veterinary medicine degree: Dr. Jonas Salk. If appropriate in the context, Dr. also may be used on first reference before the names of individuals who hold other types of doctoral degrees. However, because the public frequently identifies Dr. with only physicians, care should be taken to assure that the individual's specialty is stated in first or second reference. To avoid confusion, it is preferable to default to Professor before an individual's name, with the academic department in parentheses after the name. See doctor entry in the AP Stylebook.
