K.J. Martijn Cremers joined the University of Notre Dame as Professor of Finance at the Mendoza College of Business in 2012. Prior to that, he was a faculty at Yale School of Management for ten years, from 2002 – 2012. He obtained his PhD in finance from the Stern School of Business at New York University in 2002.

Professor Cremers' research focuses on empirical issues in investments and corporate governance. His academic work has been published in top academic journals such as the Journal of Finance, the Review of Financial Studies, the Journal of Financial Economics, the Stanford Law Review and the Northwestern Law Review. His research has also been covered in newspapers like the Wall Street Journal, the Financial Times and numerous others.

He is an Associate Editor of the journal European Financial Management (2012-present) and previously was an Associate Editor of the Review of Financial Studies (2009-2012) and of the Review of Finance (2010-2013).

At Notre Dame, he teaches courses on investments and corporate governance that integrate business and Catholic Social Teachings to MBA and undergraduate students.

His paper “How active is your fund manager? A new measure that predicts performance” (published in 2009 in the Review of Financial Studies) introduced a measure of active management named ‘Active Share’, which is the proportion of the holdings of a fund that is different from the benchmark holdings. The ‘Active Share’ measure has become widely used in the financial industry and was e.g. incorporated in Morningstar Direct and FactSet. Professor Cremers makes his Active Share data for U.S. equity mutual funds freely available on
