Martijn Cremers, the Bernard J. Hank Professor of Finance, was appointed as the Martin J. Gillen Dean for the Mendoza College of Business in 2019. Cremers previously served on the Yale School of Management faculty from 2002 until he joined Notre Dame in 2012. His research and teaching areas include investment management, corporate finance, corporate governance, and Catholic social thought.


Cremers’ co-authored 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, an innovative tool for determining the extent of active mutual fund management by measuring the percentage of stock holdings in a manager's portfolio that differs from the benchmark index. Active Share has become widely used in the financial industry and has been integrated into major platforms including Morningstar Direct and FactSet.

He serves as an independent director at Ariel Investments, an investment company located in Chicago, and has a long-standing consulting relationship with Touchstone Investments.

A native of the Netherlands, Cremers earned his master’s degree from the Free Universiteit Amsterdam and his Ph.D. from New York University’s Stern School of Business. He and his wife, Liesbeth, reside in South Bend, Indiana, with their six children.
