John H. Sinard, MD, PhD, is a pathologist who practices in many subspecialty areas but specializes in diagnosing eye diseases. When he is not examining tissue samples of patients, Dr. Sinard works closely with the pathology department’s technology team within Yale Pathology Informatics, a program that he helped build from the ground up. “We have developed in-house software that doesn’t exist anywhere else in the world,” Dr. Sinard says. “It helps facilitate the accuracy of patient specimens and provides important diagnostic information to the pathologist.” 

Similar to this specialized software system, pathologists perform necessary roles in patient care behind the scenes, Dr. Sinard explains. “A specialty physician may see between five and 10 patients each day, while a pathologist may be treating 20 to 80 patients every day.” 

At the Yale School of Medicine, Dr. Sinard currently serves as director of anatomic pathology, medical director of pathology informatics, and professor of pathology and of ophthalmology.
