Research on microfluidics sponsored by the NSF through the Harvard MRSEC has lead directly to the creation of a start-up company, Raindance Technologies. The results of the research were patented by Harvard University, and the IP was licensed to Raindance. The director of engineering at the company is a former postdoc who was supported by the Harvard MRSEC. Raindance currently employs ten scientists and engineers, and is in the process of raising additional funding for further expansion, which will lead to an additional twenty to thirty new jobs for scientists and engineers. This is a direct contribution of the Harvard MRSEC, with NSF support, to the competitiveness of our country and to the health of the US economy.
