Sag Harbor' brought me a new readership - it's a coming of age tale about growing up in the '80s.

Even growing up the way I did, I was shocked by the level of poverty I saw as a college student. I thought the best way to understand it was to get close to it on the ground level.

I don't think we can fix poverty without fixing housing, and I don't think we can address housing without understanding landlords.

I teach at Harvard, and focusing on understanding this problem on a national level is a big priority of mine right now - where evictions are going up and down, what cities are actually instituting policies that work, what housing insecurity is doing to our cities, neighbourhoods, our kids.
