About

Research engineer with a PhD in computer vision. I build deep learning systems for 3D perception — geometric learning, multi-modal fusion, and models that report when they are unreliable.

Before Konboi I built perception systems at Motional and Toyota Motor Europe. My PhD at Heudiasyc (UTC/CNRS) led to three conference papers and two international patents on camera–LiDAR calibration.

I am a Perception Research Engineer at Konboi in Paris, on autonomous trucks and AI retrofit kits for freight.

Much of my published work is in online extrinsic calibration — estimating 6-DoF transforms from ordinary driving data, without targets, with uncertainty. PseudoCal, UniCal, MULi-Ev, and WACV 2025 on KITTI, DSEC, and nuScenes.
