About Me

I'm an engineering student at CentraleSupélec working on representation learning for sensor data. Currently, I'm co-founder at ZenkoLab, where we deploy deep learning for medical imaging. I'm also exploring how hyperbolic geometry could improve world models—research that bridges my interest in geometric deep learning with practical applications.

Experience

Co-founder & CEO

ZenkoLab

Sep 2024 - Present
  • Engineered a pipeline handling high-dimensional, noisy retinal imaging data (fundus and OCT) in partnership with the Hopital National de 15-20, covering acquisition, cleaning, and validation across 200k+ annotated images.
  • Fine-tuned a Vision Transformer (RETFound) and built a hybrid architecture (ViT, EfficientNet, Random Forest) achieving 99.6% sensitivity on diabetic retinopathy and 98.6% on AMD detection.
  • Integrated Integrated Gradients, Grad-CAM, and LIME to analyze decision boundaries and failure modes in a safety-critical diagnostic setting.
