Miller's career in psychology started with research on "fear as a learned drive and its role in conflict". Work in behavioral medicine led him to his most notable work on biofeedback. Over his lifetime he lectured at Yale University, Rockefeller University, and Cornell University Medical College and was one of the youngest members of Yale's Institute of Human Relations. His accomplishments led to the establishment of two awards: the New Investigator Award from the Academy of Behavioral Medicine Research and an award for distinguished lectureship from the American Psychological Association. A "Review of General Psychology" survey, published in 2002, ranked Miller as the eighth most cited psychologist of the 20th century.
