Credibility Coalition - Economics of Misinformation Working Group

I became a member of the Credibility Coalition in early 2020. At the beginning of 2021 I became chair of the Economics of Misinformation working group.  Most recently we have been examining how programmatic advertising causes brands to unintentionally pay millions of dollars to spreaders of misinformation.

American Voter Project Collaboration

Steve Tingley-Hock of the American Voter Project (the non-profit behind the Ohio Voter Project) has been collecting voter registration data for years. In collaboration with him, I've produced two Kaggle datasets and associated example notebooks.

• ​Ohio Census Data
