Matthew (Matt) Gilley, Ph.D., knew St. Mary’s University was a great fit for him when he learned he would be able to teach topics he was passionate about. Joining St. Mary’s in 2007 as the first holder of the Bill Greehey Chair in Ethics and Corporate Social Responsibility, Gilley teaches undergraduate and graduate courses with a special emphasis on ethical leadership and corporate culture. His goal as a teacher is to inspire and empower his students to lead lives of significance and deep personal meaning.

In 2008, Gilley co-founded the Greater San Antonio Ethics & Compliance Roundtable, which has grown into a successful non-profit organization providing ethics practitioners in the region an opportunity for professional development and networking. Current and former member organizations include USAA, Rackspace, AT&T, HEB, Frost Bank, the City of San Antonio, the City of Austin, Valero Energy, Boeing, CPS Energy, Petco, NuStar Energy, Siemens, and many others.

Gilley is an Invited Academic Fellow of the Ethics and Compliance Initiative (ECI), a think-tank based in Washington, DC. The ECI is the oldest non-profit organization in the United States devoted to the study and practical application of ethics in the workplace. The ECI fellows are comprised of approximately 70 business executives from America’s largest corporations, senior government officials, and select academicians from top universities. In his work with the ECI, Gilley has led research groups examining corporate social responsibility and the evolving role of the ethics professional.

Prior to joining St. Mary’s, Gilley spent almost eight years on the faculty of the Spears School of Business at Oklahoma State University. Before moving to OSU, Gilley spent two years on the faculty of James Madison University’s business school.

Gilley has been recognized for excellence in both teaching and research numerous times. His accolades include the St. Mary’s University Alumni Association Outstanding Faculty Award, the Greehey School Service Excellence Award, the OSU Regents’ Distinguished Teaching Award (that university’s top teaching honor), and the Greiner Teaching Award, among others. His research has been cited thousands of times in studies dealing with ethics, corporate responsibility, sustainability, strategic management, leadership, human resources management, and international business.

Active in service to the community and his profession, Gilley has served the Northside Independent School District as an advisory board member for Business Careers High School since 2008. He has also provided numerous pro bono training and development workshops for non-profit organizations in the region and nationally. Gilley has served as an editorial board member for the Journal of Management and the Journal of World Business, as well as a reviewer for many leading empirical research journals and professional conferences.

Gilley has advised senior executives across the United States in organizations of all sizes, from startups to the Fortune 500, on matters related to strategy, leadership, and corporate responsibility. His clients have operated in global healthcare, automobile manufacturing, e-commerce, electric distribution, petroleum services, composites manufacturing, oilfield services, trucking, lodging, environmental management, and more.

Raised on a farm and ranch in North Texas, Gilley enjoys fishing, hunting, boating, and long-range overland travel with his wife and three children.


Gilley’s research has been published in the world’s most prestigious management journals, including the Academy of Management Journal, Strategic Management Journal, Journal of Business Ethics, Journal of Management, Journal of International Business Studies, Journal of Business Research, and others. His studies have also been presented at research conferences across the globe.
