Jean graduated from Supélec, where he majored in Applied Mathematics (MATIS). He went on to apply and develop algorithms in a variety of environments, from the LHC particle accelerator in Geneva to a web analytics startup in California. Shortly after getting his degree, he started a PhD in Deep Learning for the defense sector, where he pioneered new automatic object detection techniques for Safran. He joined Owkin as a Machine Learning Engineer to help with the implementation of distributed deep learning solutions.
