**Abstract: **Doodling has many mathematical aspects: patterns, shapes, numbers, and more. Not surprisingly, there is often some sophisticated and fun mathematics buried inside common doodles. Vakil will begin by doodling, and there is no telling where it could take him.

**Biography: **Ravi Vakil is Professor of Mathematics at Stanford University. He was born in Toronto, Canada, and studied at the University of Toronto, where he was a four-time winner of the Putnam competition (``Putnam Fellow''). He received his Ph.D. from Harvard in 1997, and taught at Princeton and MIT before moving to Stanford in 2001. He is an algebraic geometer, and his work involves many other parts of mathematics, including topology, string theory, applied mathematics, combinatorics, number theory, and more. His awards include the Alfred P. Sloan Research Fellowship, the National Science Foundation CAREER Award, the American Mathematical Society Centennial Fellowship, the Dean's Award for Distinguished Teaching, and the Presidential Early Career Award for Scientists and Engineers. He works extensively with talented younger mathematicians at all levels, from high school (through math circles, camps, and olympiads), through recent Ph.D.'s. Vakil runs a problem-solving seminar each fall for Stanford undergraduates, involving up to 150 students, as well as a masterclass for experts. He is also the faculty advisor to the Stanford Math Circle. You can read more at Prof. Vakil's Home Page.
