About

Roxane Bertrand is a leading researcher in multimodal communication and conversational dynamics, with a particular focus on engagement in human-human and human-machine interaction. Her work bridges linguistics, cognitive science, and robotics, exploring how verbal and non-verbal cues—such as gaze, gesture, and prosody—shape collaborative dialogue. In her highly cited 2023 paper, "A multimodal approach for modeling engagement in conversation," Bertrand and her colleagues established a foundational framework for automatically assessing engagement, a key variable for understanding interaction success and designing socially-aware robots. This work, which has already garnered 11 citations, demonstrates her impact on both theoretical models of conversation and practical applications in human-robot interaction. Beyond this, Bertrand’s contributions to the analysis of conversational structure and multimodal alignment have informed the development of more natural, responsive artificial agents. Her research is essential reading for students and scholars interested in the intersection of linguistics, social signal processing, and interactive AI, offering a rigorous, data-driven approach to one of the most pressing challenges in human-machine communication.
