 The Mount Sinai Health Hackathon is designed to provide a novel forum to foster experimental team science training. Utilizing a social network analysis survey, we study the impact of the Mount Sinai Health Hackathon on the nature of collaborative relationships of hackathon participants. After the event, the number of links between participants from different disciplines increased and network density overall increased, suggesting a more interconnected network with greater interdisciplinary communication. This social network approach may be a useful addition to the evaluation strategies for team science education initiatives. This article was authored by Leila Fatter, Janice Gabralov, and Faye Bradley.
