Developing the Theory and Practice of Epidemiological Forecasting

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


Epidemiological forecasting is critically needed for decision making by public health officials, commercial and non-commercial institutions, and the general public. The DELPHI group 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.
