Doris Thompson Woods, 78, who retired in 1990 as branch chief for program planning, research and analysis at the D.C. Department of Employment Services, died Nov. 4 at Reston Hospital Center.

She had chronic obstructive pulmonary disease and dementia, said her daughter, Dawn Ruffin.

Mrs. Woods worked at the Department of Employment Services for 13 years. She previously worked for 14 years at the U.S. Department of Labor in positions that included supervisory program analyst.

Doris Ann Thompson was born in Remington, in Fauquier County. She was in the class of 1950 at the old Rosenwald School in Warrenton, and was a 1954 chemistry graduate of Virginia Union University in Richmond. In the early years of her career, she was a chemist at the National Institutes of Health.

Mrs. Woods was a Vienna resident and a founding member of what is now the Northern Virginia Alumnae Chapter of the Delta Sigma Theta Sorority. In the 1970s, she held leadership positions with her chapters of the American Federation of Government Employees and Americans for Democratic Action, her daughter said.

Her marriage to William E. Woods ended in divorce. A son, Gordon L. Woods, died in 1996.

Survivors include three children, Gerald T. Woods of Chesapeake, Va., Gary B. Woods of Aurora, Colo., and Dawn A. Ruffin of Herndon; a brother, Wilbur C. Thompson Jr. of Culpeper; nine grandchildren; and two great-grandchildren.
