Last week, I went to a summer  workshop in Salt Lake City, Utah. As I checked in the university guest house, an elderly gentleman with a white shaggy beard walked to me and asked, “You must be a mathematician.”

Turns out, (as he later introduced me) he was Gregg Zuckerman, a famous mathematician working in representation theory. He knew my advisor Shahidi and was astonished Shahidi didn’t ever mention to me about him.

To his question, I replied in true mathematical spirit, “That depends on your definition of a mathematician!” leaving a chuckle behind.
