A passion for information theory and network analysis, in their own fields and beyond, brought the two biologists together with Mr. Rosvall, who is an assistant professor of physics at Umeå University, in Sweden. It’s a collaborative effort. According to Mr. West, Mr. Rosvall and Mr. Bergstrom did much of the theoretical work that produced the mapping equation, the mathematical approach that underlies much of the team’s current research. That work led to the development of InfoMap, an algorithm based on the map equation, that the team uses to build visualizations and maps of science.
