After studying mechanical engineering at the Polytechnic Institute (now the Polytechnic Institute of NYU) and receiving a master's in the same subject from Columbia, Burns began an internship at Xerox. She's been with the company ever since.
She met her husband, Lloyd Bean, while working at the company. The two have a daughter together, as well as a son from Bean's previous marriage.
