I am an urbanist and I use technology to understand and transform cities.

I work with data, make maps, and develop web applications. I also like teaching how to do these.

Currently, I'm running MedidaSP, an urban data visualization lab in São Paulo, Brazil. I also organize the local Maptime chapter here, an open learning environment on maps and data.

For the past year I've explored New York City's waste system. As part of this exploration, I've built the web tools waste.exposed, allowing individuals to understand where their waste is going; Waste Census, showing communities how they are contributing to Zero Waste; and Waste Scenario, enabling specialists to build different waste systems for the future.

Previously, I have done projects with IDEO, using design to break down barriers between different communities; with WXY, engaging residents in urban design projects; with BPE, documenting the closing of material loops in construction industry; and with 23 Sul, designing better transportation infrastructure for cities.

I also believe data can be poetic and sensorial. I've explored this through 100 Years Calendar, a digital version of the artist On Kawara's calendar; Shipping Forecasting, an automatic audio rendition of the BBC weather bulletin; and Placing Sound, an interactive installation that lets users control a soundscape.
