Ray is CTO of Element55 in Cambridge, MA. He has been a quantitative analyst since 1995, a software developer since 1998, and a founder since 2003. He cannot write backwards on a whiteboard, disqualifying him as a true data scientist. Nevertheless, he has been learning and teaching applied machine learning techniques, particularly as they relate to mobile application development.
