About me

Marc Hulcelle - Ph.D. Student

I am a second year PhD student in the Signal, Statistics and Learning (S2A) team in the Image, Data and Signal (IDS) Department of the Laboratory Treatment and Communication of Information (LTCI) at Télécom Paris, Palaiseau. My PhD research is conducted under the supervision of Chloé Clavel (Télécom Paris), Giovanna Varni (Télécom Paris), and Nicolas Rollet (i3 Lab, Télécom Paris). My work focuses on the analysis of trust in Human-Robot Interaction (HRI). In particular, I created an annotation scheme named TURIN to study trust throughout the entire interaction, and am now focusing on building multimodal computational models of trust. I aim to provide a better explanation of how trust builds and develops during an interaction with said models.

Before my PhD, I worked at Blue Frog Robotics as a robotics software engineer where I worked on developing both the AI of the Buddy robot (R&D on natural interactions, robot "personnality") and its software (architecture, remote-control application). During an academic exchange program at Tohoku University, I conducted research on obstacle detection using a time-of-flight camera for a moon exploration rover at the Space Robotics Lab.

I also hold an Engineering Degree from EMSE (France).
