Alexander Chen is a Creative Director at Google Creative Lab. In 2011, he launched MTA.ME, which transformed a New York subway map into a string instrument. This personal work led to the conception of the Les Paul Doodle, a Google doodle which generated 5.1 years worth of shared music around the world. He continued with a visualization of the Bach Cello Suites based on string physics, and a visualization of Steve Reich's Piano Phase. His personal projects have been featured by The New York Times, Wired, Fast Company, Wall Street Journal, and others.

At Google, he has helped lead projects such as Chrome Music Lab (for exploring how music works) and A.I. Experiments (for exploring machine learning). He plays viola and other instruments, and is currently living in Massachusetts.
