I am an Associate Professor (HDR) of Computer Science at IMT Atlantique. I am part of the INUIT research group of Lab-STICC. My research interests include Human-Computer Interaction, Virtual Reality and Augmented Reality, Computer-Supported Cooperative Work, Telepresence and 3D Interaction. I received an Habilitation (French HDR) from Université Paris-Saclay in February 2024, entitled: “Supporting Collaboration in Large Interactive Spaces”.

Before that, I was an Associate Professor at Université Paris-Saclay (2013-2021) in the ex)situ research group. I was also a postdoctoral fellow at University of North Carolina and a visiting researcher at Nanyang Technological University (2012-2013) working with Pr. Henry Fuchs. I completed a PhD in Computer Science at INSA de Rennes (2008-2012) under the supervision of Pr. Bruno Arnaldi, Pr. Thierry Duval and Dr. Valérie Gouranton.

Research

My research work is at the crossroads of Human-Computer Interaction (HCI), Virtual and Augmented Reality (VR/AR) and Computer-Supported Cooperative Work (CSCW). I study how humans communicate with computers, but also how humans communicate among them through computers. Although part of my research focuses on collaboration through immersive technologies including virtual and augmented reality, my contributions are broader in the HCI domain including work on interaction design and video-mediated communication.
