Suprio Das - India - 2010

After working for more than 20 years as an electrical engineer, Suprio realized that life could be more meaningful and interesting than a scramble up the corporate ladder. He gave up his job and started his own business while volunteering with an NGO in villages around Kolkata. On a visit to the villages, it occurred to him that social work and engineering could be combined together to develop devices that could help the poor. The simple devices that he started designing brought him in touch with MIT D-Lab, and he was invited four consecutive times to IDDSes in Boston, Ghana, and Colorado. Suprio is a 2014 D-Lab Scale-Ups fellow.
