Paul Blanchard is professor of mathematics at Boston University. He grew up in Sutton, Massachusetts, USA, spent his undergraduate years at Brown University, and received his Ph.D. from Yale University. He has taught mathematics for more than thirty years, mostly at Boston University. His main area of mathematical research is complex analytic dynamical systems and the related point sets---Julia sets and the Mandelbrot set. He is a Fellow of the American Mathematical Society.

He is the author of Calculus, 3e with Dennis Berkey. For many of the last twenty years, his efforts have focused on modernizing the traditional sophomore-level differential equations course. That effort has resulted in numerous workshops and minicourses. He has also authored five editions of Differential Equations with Robert L. Devaney and Glen R. Hall. When he becomes exhausted fixing the errors made by his two current coauthors, he heads for the golf course to enjoy a different type of frustration.
