Boston Cyclists Union

A collection of posts about my work at the Boston Cyclists Union an advocacy organization in Greater Boston fighting for better infrastructure and rights to serve cyclists of all ages. I did data and GIS work for them, building an online crowdsourcing map that enables users to draw in routes and drop markers where they would like better infrastructure.

COPPE-LTC

After finishing my double Masters’ in Transportation and City Planning at MIT in 2015, I got MISTI funding to go to Rio for a research internship. I worked for the LTC, the Cargo Transport Lab at UFRJ, the federal university of Rio de Janeiro located on Ilha do Fundao, an island near the international airport. My project aimed to reduce GHG emissions from people commuting to the island.
