Introduction
Bruno Gonçalves is an associate professor at the University of Évora and research at the CHRC. He graduated with a PhD in collective movement behaviour in association football in 2017, where developed expertise in capturing and filtering data using high-tech instruments and also in advanced processing computations. This expertise has led him to build a solid national and international reputation in collective movement behaviour and team sports performance analysis.
