The interdisciplinary research carries out in the React Group aims at handling coordination and interaction challenges using systems engineering methodologies. The underlying approach is to exploit in an integrated manner the dynamical couplings that exist between users, devices and information systems to ease adoption and improve usability in distributed frameworks. Innovative domains of deployment are cyber physical systems, autonomous transportation systems, social media for digital education and knowledge management, as well as humanitarian technology. The React Group is affiliated with the EPFL Transportation Center (TRACE) and with the Center for Learning Science (LEARN).

The two main research topics currently investigated in the Group are Coordination Systems and Interaction Systems.

The current focus in Coordination Systems is on advanced structures and algorithms for the real-time operation of distributed devices where dynamics matters, with application to intelligent transportation systems (intersection of connected automated vehicles at roundabout) and astrometry (coordination of optical fiber positioners). The underlying academic domains are optimal, predictive, and reactive control.

The current focus in Interaction Systems is on mobile and Web platforms where usability and adoption matter, with application to digital education, knowledge management, as well as digital humanitarian technology. The underlying academic domains are Human Computer Interaction (HCI), Engineering Education Research, and Technology Enhanced Learning (e-Learning)..

React is affiliated with the EPFL doctoral programmes in Computer and Communication Sciences (EDIC), Electrical Engineering (EDEE), as well as Robotics, Control, and Intelligent Systems (EDRS).


The REACT Group is affiliated with the upcoming EPFL Center for Learning Sciences (LEARN) which will be inaugurated on October 10, 2018.

The Swiss EdTech Collider Association has been created on November 18, 2016, to promote solutions for Digital Education. Co-founders are Pierre Dillenbourg (Président), Denis Gillet (Vice-Président), Francesco Mondada (General Secretary) and Marcel Salathé (Treasurer).

Denis Gillet is the Deputy Coordinator of the new H2020 Next-Lab Project supporting Next Generation Stakeholders and Next Level Ecosystem for ColLaborative Science Education with Online Labs (6.3M€).

Denis Gillet was interviewed by the RTS in “InterCités” about SpeakUp, the mobile app supporting digital interaction in large classrooms.

The React Group got the best paper award at the EC-TEL Conference 2016 for its contribution on Best paper award at EC-TEL 2016: Examining the effects of social media in co-located classrooms: A case study based on SpeakUp“, by María Jesús Rodríguez-Triana, Adrian Holzer, Luis P. Prieto, and Denis Gillet.

Denis Gillet was interviewed by the Swiss television about the ongoing work on autonomous and connected vehicles crossing at intersections (investigations carried out by Laleh Makrarem and Ezequiel Debada).
