My essay, Beyond β€œData Good” or β€œData Bad” (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.

I'm pleased to have contributed an essay to the latest Spotlight On series from @ijurresearch.bsky.social called "Counting the City". The series has four essays on the ethics, methods, and politics of using big data to understand the city.

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...

How did the US become a land of opportunity? In a new paper, we show that the country's pioneering role in mass education was key to its rise in intergenerational mobility from 1850 to 1950.

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:

Upon learning that yesterday would be my last day as a program officer at the National Science Foundation, I shared this parting message with my colleagues. The next few months will be frenetic and stressful for them. Here are some things that you can do to help them with the mission ahead. (1)

Terrible, monopolistic landlord in Hyde Park, Chicago, Mac Properties, is sued for housing discrimination, steering voucher holders away from some buildings and toward others.

Yay for Hope Fair Housing!

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.
