In this talk, I will present some of our recent projects and studies analyzing how technologies and network science can support team formation. First, we will show how individuals’ decisions of collaborators are influenced by their social networks. We conducted a field study with more than 800 participants, examining how they formed teams and picked their collaborators. Second, we will present the results of a laboratory experiment testing how algorithms can orchestrate different team compositions by altering the order of recommendations. Lastly, we will analyze how their social capital and networks can explain scientific teams’ disruption. These studies contribute to a better understanding of how team composition and formation influence their performance and cohesion.
