Biography:

Glenn Hurlbert is an Emeritus Professor from the School of Mathematics and Statistical Sciences. He joined ASU in 1990. He is presently with Virginia Commonwealth University, as of 2014.

Hurlbut was named a President's Professor in 2012. He said, upon receipt of his award, “As soon as students enjoy what they are doing they become ripe for learning. The best teacher in the world cannot force anyone to learn, but a willing learner can learn from anyone. It is, therefore, my first task to create willing learners. The challenge then is to create a safe environment for thinking, guessing and questioning in which students can speak freely without fear of ridicule.”
