Martijn's Expertise

Martijn has served as the Martin J. Gillen Dean of the Mendoza College of Business at the University of Notre Dame since July 2019 and has been on the faculty at Notre Dame since 2012. He was appointed as the Bernard J. Hank Professor of Finance in 2018. Previously, he was a faculty member of the Yale School of Management for 10 years. His paper, “How Active is Your Fund Manager? A New Measure That Predicts Performance” (published in 2009 in the Review of Financial Studies) introduced “Active Share,” a new measure of active management. This innovative analysis is based on a comparison of fund holdings versus those of its benchmark and has become widely adopted throughout the financial industry. Martijn earned undergraduate and masters degrees in econometrics from the Free University Amsterdam and his PhD in finance from New York University’s Stern School of Business.
