François Bouchet received a Master’s degree in Engineering from ESIEA and in Computer Science from University Paris-Sud 11 in 2005 and 2006, respectively, and a PhD in Computer Science from University Paris-Sud 11 in 2010. During those years, his research interests gradually evolved from cor- pus analysis and Natural Language Processing of requests made to assistant conversational agents, to the design of architectures for believable cognitive agents with personality and emotions. He is now a postdoctoral fellow at McGill University, in Pr. Roger Azevedo’s team, working on emotionally-aware agent-based intelligent tutoring systems. Sybille Caffiau is Assistant Professor at the University Joseph Fourier at Grenoble (France) and performs its research at the LIG (computer science lab of Grenoble). Her research is at the intersection of ergonomics, model-driven engineering, and human computer interaction. She works on user-centered design of interactive applications. Her work is based on the use of models in an iterative approach for which the design is validated by the user activity that is expressed from specifications, evaluations, and feedback in the form of task models. She is author of several papers on national and international conferences and journals.
