Data scientist has been called the sexiest job of the 21st century. As organizations wrestle with the ocean of data generated by mobile devices, social computing, the cloud, and other technologies, data scientists help turn this information, known as Big Data, into insights companies can use.

Andrew Schwartz is a data scientist and cofounder of Lattice Engines, a data analysis firm in Boston. He lives on a sailboat on Boston Harbor; rides a bright, green recumbent bike to the office, and does his best work between midnight and 4 a.m. “To really understand a problem,” he says, “it helps to be completely isolated with my computer.”
