ISE Associate Professor David Mendonça and Cognitive Science Professor Wayne Gray recently received an RPI Presidential Graduate Fellowship to support groundbreaking research on teamwork in high tempo, adversarial environments. The project will employ data from the online game League of Legends (LoL). With approximately 70 million registered players and 12 million daily players, LoL is the most popular game in the world. Mendonça and Gray, along with Matthew Sanger--the doctoral student who will be supported by this fellowship--will investigate processes of individual- and team-level learning and performance in multiplayer teams. The scope and scale of the LoL data are many orders of magnitude beyond those typically found in teamwork studies, allowing for deep and broad investigation at milisecond- through minute-levels for teams whose lifetimes can extend over multiple years. The project also represents a noteworthy interdepartmental collaboration: Mendonça and Gray hold joint appointments in each other's respective departments, and the fellowship recipient will be co-advised by them.
