My new article, "Clean Slate, Dirty Data," audits automatic non-conviction record clearance laws in 5 states, finds good but imperfect compliance, suggesting 1) automation can succeed where petitions fail, 2) accountability in implementation is needed.(NC L. Rev 2025)

Dear journalists:

The President has not fired Lisa Cook. The President is *trying* to illegally fire her.

Despite backlash to DEI, our paper, w/ Jillian Grennan and Jason Sandvik, just presented @nber.org, suggests targeted mentorship boosts firm-wide innovation. Tracking 7 cohorts, 633 mentees & 20K+ employees, we find real ROI for well-designed mentoring.

By providing data for evaluating RJA claims, we aim to level the field for those seeking discovery/relief based on disparity evidence. Analyze your case against broader patterns; see our LA County burglary analysis (2013-2014).

Last week, I spoke on @npr.org's Morning Edition on the importance of policy delivery, not just fanfare, in reference to @govwesmoore.bsky.social's sweeping and ambitious pot conviction pardons; the TL;DR: good start, keep going.

Some say Maryland’s mass marijuana pardons don’t go far enough

This week Maryland Gov. Wes Moore pardoned 175,000 people with marijuana convictions. But some advocates say pardons might not be enough to remove the barriers faced by people with a criminal record.

New(ish) study with Duke Prof. Arti Rai considers Dx #patenting following SCOTUS’ Mayo ruling. We find increased prosecution toughness, sustained patenting but some evidence of retrenchment in filings/filing quality among small, US-based firms. Paper: papers.ssrn.com/sol3/papers.... 📈 #PatentLaw
