I am a Professor of Mathematics at Stanford University, the Robert K. Packard University Fellow in Undergraduate Education (2008-2013), and the David Huntington Faculty Scholar. I was the 2009 Earle Raymond Hedrick Lecturer at Mathfest. I have received the Dean's Award for Distinguished Teaching, an American Mathematical Society Centennial Fellowship, a Frederick E. Terman fellowship, an Alfred P. Sloan Research Fellowship, a National Science Foundation CAREER grant, the presidential award PECASE, and the Brown Faculty Fellowship. I have received the Coxeter-James Prize from the Canadian Mathematical Society, and André-Aisenstadt Prize from the CRM in Montréal. (This may give you a clue that I am Canadian.)
