Yesterday I had the pleasure to give a seminar at the Learning Planet Institute (fka. Center for Research and Interdisciplinarity or CRI). This institution belongs to the University of Paris and was created in 2016 to co-constructing and sharing new ways of learning, teaching, conducting research and mobilizing collective intelligence in the fields of life, learning and digital sciences. My participation was originated through an invitation by Marc Santolini, leader of the Interaction Data Lab, a team at CRI focused on deciphering collective phenomena at biological and social scales through network science and data analysis. The goal of the session was for me to share findings from my PhD research on characterizing online participation in civic technologies. Attendees were extraordinarily active and brought many good questions to the discussion, so this was one of the seminars I have enjoyed the most to date.
