Research

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  psychological well-being. He has conducted research in laboratory environments with the Center for Behavioral and Decision Research (Carnegie Mellon) and 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 psychological 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 has presented his work at a variety of conferences, including the annual meetings of the Association for Psychological Science and the Interdisciplinary Network for Group Research (INGRoup) and is slated to present his work in the summer of 2019 at the annual meetings of INGRoup, the Academy of Management, the Columbia/NYU East Coast Doctoral Conference in Management, the Association for Computing Machinery Collective Intelligence conference, and the Carnegie Mellon University Innovation and Impact Exhibition.
