BIOGRAPHY

Dr. Gelber obtains his PhD in the field of Applied Probability and Statistics from Cornell University in 1975.

He starts working for the DFCI in 1977, and until 2006 is coordinating statistician in the Pediatric Acute Lymphoblastic Leukemia Consortium.

He is also statistical director of the Pediatric AIDS Clinical Trials Group from 1988 to 1998. Since 1978, Gelber is Statistical Director of the IBCSG. In these years he co-develops two statistical methods for the interpretation of clinical trial data: the described Q-TWiST and the Subpopulation Treatment Effect Pattern Plots (STEPP), which makes easier to interpret the effects of treatments in distinct patient subpopulations.

Gelber becomes a fellow of the American Statistical Association in 1993, while in 1997 he is awarded an Honorary Doctorate in Medicine from the Swedish University of Göteborg. He is now senior statistician for both the IBCSG and the Breast International Group (BIG).
