Max Halperin, 70, the director of the Biostatistics Center at George Washington University and a former chief of the Biometrics Research Branch at the National Heart, Lung and Blood Institute of the National Institutes of Health, died of cancer Feb. 1 at Fairfax Hospital.

Dr. Halperin was an internationally recognized authority in his field, which uses statistics to conduct medical research. He helped design the statistical aspect of numerous clinical studies, particularly in the field of heart disease, and he published more than 60 papers in professional journals.

Among the studies on which he worked was the Coronary Drug Project at NIH, which evaluated the usefulness of some drugs in prolonging life after a heart attack. He also worked on the Hypertension Detection and Followup Program at NIH. This showed that hypertension should be treated aggressively, and it led to the adoption of the guideline that blood pressure of more than 140/90 warrants treatment.

Dr. Halperin, who lived in Reston, had been a professor of statistics and head of the Biostatistics Center at George Washington University since 1978. The center is largely funded by NIH.

He was a fellow of the American Statistical Association and chairman of its biometrics section. He also was a fellow of the American Association for the Advancement of Science and the Institute of Mathematical Statistics and a member of several other learned societies. He was a member of the advisory committees of NIH, the Food and Drug Administration and the National Research Council.
