Developing the Theory and Practice of Epidemiological Forecasting

December 2016: CDC has just named us “Most Accurate Forecaster” for 2015-2016.

October 2017: We did it again! Our two systems took the top two spots out of 28 submissions in the 2016-2017 flu challenge.


Epidemiological forecasting is critically needed for decision making by public health officials, commercial and non-commercial institutions, and the general public. The Delphi group at Carnegie Mellon University focuses on developing the technological capability of epi-forecasting, and its role in decision making, both public and private. Our long term vision is to make epidemiological forecasting as universally accepted and useful as weather forecasting is today.
