Jon S. Morrow, MD, PhD, the chair of pathology for nearly 30 years, has spearheaded innovative programs in the department during his tenure. He ensured, for example, that pathologists adopted the use of data and information systems as early as possible and applied those tools to track and update the status of tissue specimen samples—long before electronic medical records came into the picture. “We were also the first adopter in the Northeast to use computer-assisted cytologic screening,” Dr. Morrow says, referring to a diagnostic test that involves studying a patient’s cells. 

In more recent years, Dr. Morrow has focused on incorporating the latest genetic sequencing technology into pathology’s testing labs to conduct more accurate cancer tumor profiling. “We can now do tumor profiling on infinitesimally small tissue samples from the lung, breast, colon or prostate, to name a few,” he says. 

As the Raymond Yesner Professor of Pathology at Yale School of Medicine, Dr. Morrow conducts basic pathology research that has earned him renown in the field. He has pioneered studies on the structure, function and genetics of complex cell membrane scaffolds that have provided insight into the pathologic basis of a variety of hematologic and neurologic disorders.
