Crossan is a Distinguished University Professor – Western's highest honour recognizing excellence in teaching, research and service over a substantial career at Western. In 2021 she was recognized on a global list representing the top two per cent of the most cited scientists in her discipline. She teaches in the undergraduate, MBA, Ph.D. and Executive Programs. Her research on organizational learning, strategy, leadership character and improvisation has been widely published in such journals as the Strategic Management Journal, Academy of Management Review, Organization Science, the Journal of Management Studies, Leadership Quarterly and Organization Dynamics. She has extended her research to management practice through a collection of over 50 cases, many of which have been published in a book she co–authored entitled Strategic Management: A Casebook. She is also an author of the Strategic Analysis and Action textbook. In a joint venture between the Ivey Business School and the Second City Improvisation Company, she developed a management video entitled "Improvise to Innovate" which extends traditional concepts of strategic management to development tools and techniques for more innovative, flexible and responsive strategic action. Her recent research focuses on the development of leader character as a critical foundation to support and elevate leader competencies. She and her colleagues have developed courses, cases, and a diagnostic assessment to develop leader character. The “Developing Leadership Character” book is a culmination of the team’s research on leader character. She is also a co-host of the Question of Character podcast series. She works with organizations around the world on developing and investing in leader character.
