Most of research is completed through a research team where team members’ expertise and knowledge complement with each other. In academic contexts, research project generally involve the establishment of multi-disciplinary and competent research teams to simultaneously consider various activities throughout the entire research project. To ensure a successful research team, it is important to understand and model researchers’ characteristics in an appropriate and systematic way. Three fundamental descriptors of researchers are developed in this research. The first is to represent researchers’ expertise level in areas related to project. The second is to consider the team members’ diversity in their expertise. The third is to develop a measurement of team members’ working relationships based on their previous co-authorships and personality characteristics. This research helps construct a team for a research project based on these characteristics.
