I am a Ph.D. Candidate at the Vanderbilt University School of Engineering, a Research Fellow at Vanderbilt Law School’s Program on Law & Innovation, and a Co-Founder of PredictGov, Inc.

Interactively explore real-time predictions for the more than 9,000 bills currently under consideration in the U.S. Congress at

New Partnership: To further our overall mission of improving law with technology, we partnered with, which is the first organization to provide open data on Congress and one of the most used resources for tracking federal legislation. Pending bills in Congress have a PredictGov probabilistic forecast and explanation of important predictive factors for the bill displayed on GovTrack’s website. We are excited about partnering with a leader in civic technology.
