Ph.D. in Computer Vision and Machine Learning
Head of AI, ActiveEon, Paris, France
I am a computer vision specialist with over a decade of experience in research and industry, specializing in the intersection of Artificial Intelligence (AI), High-Performance Computing (HPC), and MLOps. As the Head of AI at ActiveEon, I lead a team of AI researchers to develop cutting-edge scalable AI workflows for distributed and parallel execution, including automated machine learning (AutoML) and hyperparameter optimization at scale.
