Climate CoLab, an MIT-based crowdsourcing platform to advance climate change solutions through the power of collective intelligence, has named Langley DeWitt, a research scientist with the Center for Global Change Science, as a Judges’ Choice winner in one of 15 contests for 2015. DeWitt, who is also chief scientist of the Rwanda Climate Observatory, was recognized in the Transportation contest for her proposal to set up an inexpensive air quality sensor network in Kigali, Rwanda as part of an effort to reduce vehicular emissions and improve air quality.

DeWitt and other contest winners will present their ideas at MIT's Solve and Crowds & Climate conferences, October 5 and 6 on the MIT campus, where the $10,000 Grand Prize will be awarded.
