This past summer, Amy Strosser, worked on two mathematical research projects in graph theory at Rochester Institute of Technology. A group of students, along with Amy, analyzed data that was recorded from the MRI's of football player's brains. They used graph theory metrics to determine whether the communication between brain regions had changed from preseason to postseason. They concluded that the number of hits a player took affected the communication connectivity of the player's brain. Amy and her partner worked on a second project, in which they discovered an algorithm called Walk Modularity that can detect communities within graphs. A community is a set of vertices that is well-connected by edges within a graph.
