Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues, bodily fluids, and in some cases, the whole body. Clinical pathologists are physicians who specialize in the diagnosis and management of diseases by laboratory methods. 

Cytopathology is a branch of pathology that studies and diagnoses diseases on the cellular level. A cytopathologist is an anatomic pathologist trained in the diagnosis of human disease by means of the study of cells obtained from body secretions and fluids; by scraping, washing, or sponging the surface of a lesion; or by the aspiration of a tumor mass or body organ with a fine needle.

On a more personal note, Dr. Jean is a member of U.S. Masters Swimming, a nonprofit membership national governing body for masters swimming, an organized program of swimming for adults.
