Patrick T. Harnett, a social worker and assistant professor at the University of Maryland, died of cancer Tuesday at Johns Hopkins Hospital. Dr. Harnett, who was 39, lived in the Hamilton section of Baltimore.
A mass of Christian burial for Dr. Harnett will be offered at 11 a.m. tomorrow at St. Dominic's Roman Catholic Church, 2910 Echodale Avenue.
He had been incapacitated since September, when a brain tumor was diagnosed and the malignancy spread to his lungs, spinal fluid and bone marrow.
Specializing in mental health and the aging, Dr. Harnett was a clinical social worker at the University of Maryland Institute of Psychiatry and Human Behavior and taught courses in social work and the psychology of aging.
Since 1989, Dr. Harnett had been an assistant professor of social work at the University of Maryland at Baltimore. He had been an instructor in Towson State University's psychology department since 1981 and taught at Loyola College in the early 1980s.
The New Jersey native was reared in Philadelphia and moved to Baltimore in 1975.
He received his undergraduate degree in 1975 from Wheeling College in West Virginia, where he acted in theatrical productions.
He received a master's degree from Loyola College in Baltimore in the early 1980s, and his doctorate in social work -- and an additional doctoral certificate in gerontology -- from UMAB in 1986.
At the university institute, he worked with elderly psychiatric patients in both individual and family therapy.
Dr. Harnett's first research article, "Patterns of Emergency Department Use by Geriatric Patients," is to be published in the spring in the Journal of Gerontological Social Work. He was working on two others when he became ill.
Dr. Harnett sang tenor, played the piano, and enjoyed white-water rafting and basketball.
He was a member of the National Association of Social Workers and a parishioner at St. Dominic's Church.
Surviving are his wife of four years, the former Susan A. Mangano; a 3-month-old son, Patrick Jeremiah Harnett; three brothers, Daniel J. Harnett and Joseph Harnett, both of Philadelphia, and Michael T. Harnett of Cambridge, Mass.; a sister, Kathleen Makowka of Connecticut; and nine nieces.
The family suggested donations to cancer research.
