What's the secret to a high-performing team? A star player? Veteran experience? In a joint study by Dropbox and the Northwestern Institute on Complex Systems (NICO), we set out to answer questions like these by analyzing Dropbox collaboration at the top 100 universities in the world (based on the 2017 Center for World Universities Rankings) and cross-referencing academic citations according to the Web of Science database. To protect our users' privacy, all data was anonymized and information like university ranks and number of citations were grouped into ranges.
