Matthew Diabes is a PhD Candidate in Organizational Behavior and Theory at the Tepper School of Business at Carnegie Mellon University. Previously, Diabes received an MS in Industrial Administration from Tepper and a BS in Psychology and Philosophy and a certificate of Public and Professional Writing from the Kenneth P. Dietrich School of Arts and Sciences at the University of Pittsburgh.

His research is motivated by the central question, "What conditions enable positive, productive interpersonal relationships to emerge, and how are they maintained?" Specifically, his research interests include the formation and management of relationships, communication and coordination processes, interpersonal trust and knowledge-sharing on teams, and the organizational value of well-being. He has conducted research in laboratory environments with the Collaboration and Conflict Research Lab (Carnegie Mellon), the Center for Behavioral and Decision Research (Carnegie Mellon), and at the University of Pittsburgh as well as in field settings in the financial and health care sectors.

His current projects address research questions about:

  • The impact of individual well-being on the emergence of trust, knowledge-sharing, and coordination processes on teams
  • The effects of team dynamics on the performance of high-stakes teams
  • The processes that enable geographically-dispersed teams to maintain knowledge-sharing relationships
  • Strategies to repair intra-team relationships following transgressions

Diabes was a 2019 recipient of the NTR-Peterson Research Grant from the Negotiation & Team Resources Institute (proposal ranked 1st of 20 proposals, 2019) and has presented his work at a variety of conferences, including the annual meetings of the Academy of Management, the Interdisciplinary Network for Group Research (INGRoup), and the Association for Psychological Science.
