Konstantinos Mattas received the degree in civil engineering specialized in transportation, the M.Sc. degree in applied mathematics from the Democritus University of Thrace, Xanthi, Greece, and the Ph.D. degree from the Democritus University of Thrace, with a focus on fuzzy logic applications in transportation engineering. Since 2017, he has been with the Joint Research Centre, European Commission. His research interests include intelligent transportation systems, simulation of vehicle dynamics and driver behavior, microscopic simulation of traffic networks and network control, optimization, and traffic safety. He was part of the team developing and sharing the OpenACC dataset, an openly available group of data coming from road and test-track experiments on commercially available driving automation systems. He has been supporting the development of the first international regulations on automated driving.
