I am a computer vision, machine learning and remote sensing researcher. I hold a PhD in Computer Science prepared at ONERA and IRISA, supervised by Sébastien Lefèvre and Bertrand Le Saux. My thesis was about teaching computers how to look at airborne images to create beautiful maps. My research now focuses on deep neural networks (deep learning) for artificial perception, ranging from document image analysis to remote sensing and Earth Observation. Specifically, I am currently working on multimodal learning for image/text understanding in administrative documents.
I am interested in machine learning, algorithms and Python.

I graduated in 2015 from Supélec, one of France's top engineering school, with a focus on Computer Science. I also graduated from the université Paris-Sud with a MSc in Human-Computer Interaction. While I was an engineering student, I was head of the Supélec Rézo organization that provides Internet access to all Supélec' students.
I did my final intership in the Computer Vision lab at TUM under Pr. Daniel Cremers supervision. I worked on deep learning for facial expression recognition.
From October 2015 to October 2018 I was a PhD candidate at ONERA.
Since January 2019 I am a research scientist at Quicksign.
