Co-founded and co-lead a network of advocates working to ensure state transportation infrastructure spending reduces pollution—and household costs.

I work to align transportation policy and public investment with real-world outcomes that matter—healthy people, thriving communities.

Zak Accuardi, a senior program analyst with the Transit Center, a research organization, has suggested that the M.T.A. measure performance using a tool used in London called excess journey time. “The A Line has a 12-month weekday wait assessment of 71.9 percent, but what does that mean for riders?” Mr. Accuardi wrote to board members this summer. “Wait assessment is indifferent to how late a train is or how many riders are affected by its lateness.”
I am drawn to messy, complex systems—understanding what drives them, and what changes might help align their machinations with public good. For more than ten years, I've focused on the built environment, working to leverage public investment in transportation infrastructure to promote more affordable, more vibrant, and less-polluting communities. At NRDC I lead U.S.-based policy advocacy at local, state, and federal levels to grow investment in public transit, sidewalks, and safe biking infrastructure.
In past professional lives, I wrote or co-wrote national policy best practice reports; led a range of quantitative analysis projects; and managed a million-dollar technical assistance consultant to accelerate transportation project and policy implementation in more than twenty U.S. cities. My work has been cited in a cover story in one of my hometown papers ( Street Roots ) and in the New York Times. I studied environmental engineering at Columbia and hold a MS in technology & policy from MIT.
At home in Berkeley, California, the strongest pro-transit voice belongs to my toddler, to whom anything with wheels is called a BUS! I do, in fact, enjoy walking, biking, and taking buses and trains—especially when they help me access beauty in the natural world (or perhaps in a modern art museum). I make beautiful coffee at home in a rebuilt espresso machine—though less ice cream now than I did when I was writing Churning Man (come to think of it, I don't drink nearly enough affogatos). I have inconsistent musical and mindfulness practices, and I believe in leaving things better than we find them.
