John Deke, PhD

I am an economist and nationally recognized expert in experimental and non-experimental impact evaluation methodology, Bayesian inference, and the interpretation of impact and descriptive findings. I bring more than two decades of experience designing and analyzing experimental, quasi-experimental, and descriptive evaluations for OPRE, IES, CMS, and OPA.

As a Senior Fellow at Mathematica, I co-led the development of BASIE (Bayesian Interpretation of Estimates), an approach now used across federal agencies to provide transparent, probability-based interpretation of both impact estimates and descriptive differences between groups or across time. BASIE empowers more useful, comprehensive, and integrated interpretation of heterogeneous research findings.
