Main activities

• Build an image processing pipeline sampling skin color at multiple facial locations, with automated quality gating (facial segmentation, rejection of specular highlights, shadows and occlusions)
• Quantify measurement precision: variance decomposition across subject, site, imaging system, viewing angle and visit; repeatability and test–retest analysis
• Characterize and correct or statistically account for differences between imaging systems
• Develop a calibrated probabilistic model estimating Fitzpatrick skin type with explicit uncertainty, and a logic for flagging discordant cases for human review
• Run pre-specified robustness and fairness checks across the measured skin tone range
• In a second phase, as a support project, contribute to other AI Lab initiatives such as Noesis (Teoxane’s internal AI assistant) and LightRAG-based document processing
• Document methodology, results and code to ensure project continuity

Your profile

• Ongoing Master’s in Data Science, Applied Statistics, Engineering, or a related field
• Strong Python: NumPy, pandas, scikit-learn, and image processing (OpenCV, Pillow)
• Solid applied statistics: variance components, uncertainty quantification, calibration
• Familiarity with PyTorch; interest in colorimetry (CIELAB), LLMs and RAG is an asset
• Curious, rigorous, autonomous; works well independently and in a cross-functional team
• Fluent in English; French is an asset
