About Julien
I have been working almost 3 years at Tinyclues, as a R&D data scientist (Recommender systems).
I have also worked in a cardio-imagery start-up developing deep learning solutions for diagnostics, at Collège de France (Paris) in the mathematical neurosciences team, and in a Californian Start-up developing computer vision solutions for agriculture.
I graduated from Ecole Polytechnique and National University of Singapore, in Data Science.
Specialized in Deep learning and Bayesian modelling, I have also had the chance to work on a very wide range of subjects: Natural Language Processing, Computer vision, Time Series Prediction, Audio Analysis, Biotechnologies, Data Mining, ...
