I am Edouard Oyallon, a member of the *Centre de Vision Numérique (CVN) de CentraleSupelec*. Prior to it, I was a postdoctoral research fellow at the *INRIA Lille*, where I worked in particular with Michal Valko. I obtained my PhD in October 2017 from the *Département Informatique de l'Ecole Normale Supérieure* under the supervision of Prof. Stéphane Mallat. I graduated from the *ENS Cachan, campus de Ker Lann*. My current main research topic is to understand the theoritical fundations of feature engineering methods.

I hate black box pipelines, and to be concise, the type of questions I try to solve is not “how to learn new deep features that discriminate this image as a dog”, but simply “why is your network understanding that this signal is a dog”. Answering such questions could help to make fundamental advances in science in a context where too much work is dedicated to techniques that give incremental improvements on standard datasets.

Feel free to send me any emails to discuss my work at __edouard[dot]oyallon[at]centralesupelec[dot]fr__.

**News:**
Feb 2018, I am grateful to have received a GPU donation from NVIDIA.

Jan 1st 2018, I will join the CVN at CentraleSupelec.

Nov 1st 2017, I will join the SequeL team at Lille, to work in particular with Michal Valko and Matteo Pirotta.
