I lead consulting for predictive modeling and data science at Gallup and am a big fan of the R programming language. I also moonlight as a baseball researcher and have consulted for several Major League teams.
My public baseball research can mostly be found at The Hardball Times.
I have also developed a number of public tools for baseball analysis, such as the baseballr package for R, the Interactive Spray Chart Tool, and the Edge% app. For more information on these tools, visit the Baseball Tools page.
