What do you enjoy about teaching?
"I have a photograph of myself at the age of five writing numbers on a blackboard. Obviously, I was destined to teach mathematics. I love to help people appreciate the beauty and utility of mathematics and I take great satisfaction in knowing I've helped innumerable students develop confidence in their ability to make sense of an increasingly complicated world."
