My essay, Beyond βData Goodβ or βData Badβ (please permit the facetious title!), explores how I approach novel forms of data analysis as part of a more pluralistic set of methodologies. I discuss how this perspective has shaped much of my work over the past several years.

The Crisis of Affordability in New York City .pdf
Absolutely no mention of additional zoning reforms or anything about bolstering housing production other than 'experts say more production helps to lower costs.' It's honestly disappointing for a former HUD chief and governor, who's spent 30 years on these issues -- drive.google.com/file/d/1HyUV...

We're not done yet | 18F
I got laid off today, with the rest of 18F.
18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it.
We made this website to tell our story:

We wrote this piece last month based on our study using looking at the racial composition of police stops vs traffic camera stops for traffic violations. Unfortunately, but not surprisingly, we found that police stops were much more biased against black drivers. Glad its making the rounds.
