Meet Jean Berko Gleason—psycholinguist by profession and speed demon on the side. She is one of the scientists that we are profiling on "The Secret Life of Scientists and Engineers," a web-exclusive series from NOVA. Every two weeks, you'll have a chance to meet a new scientist or engineer. Watch their videos. Ask them questions. Find out how their surprising secret lives fuel their science, and vice versa.
