Stephen D. Senturia spent 35 years as Professor of Electrical Engineering at the Massachusetts Institute of Technology. He has been involved in micro-sensor and MEMS research since the early 1970’s, working on dielectric sensors, polymers in micro-electronics, methods of material property measurement, CAD tools for MEMS, and the Polychromator, a diffractive MEMS device. Since retiring from MIT in 2002, Dr. Senturia has served as Chairman and Chief Technology Officer of Polychromix, a company built on the Polychromator technology. Honor and professional societies include the National Academy of Engineering (Fellow), the IEEE (Fellow), Phi Beta Kappa, and Sigma Xi. In 2004, he was elected to a six-year term as President of the Transducer Research Foundation, a non-profit organization dedicated to the promotion and dissemination of research in micro-systems.
