Short Bio
Oriane Siméoni is a Research Scientist in the team DINO of Meta FAIR specializing in computer vision with a focus on methods that require no human-made annotation. Previously, she spent over three years as part of the research team valeo.ai, where she was already concentrating on vision solutions using little to no annotation. She did her PhD at Inria Rennes--Bretagne Atlantique under the supervision of Yannis Avrithis and Guillaume Gravier. During her PhD, she performed two internships at Twitter and Google and visited the Visual Recognition Group (CVUT).

Longer Presentation
I am currently working as a Research Scientist in the research team valeo.ai, focusing on perception issues. My research focuses on computer vision. I study methods to compute robust visual representations whilst having the aim of using less supervision and exploiting more available data. In particular I have worked on classification, detection and retrieval tasks. I am interested in image representation, multimodal learning and machine learning in general.
I have defended my PhD on the 10th of September 2020 (delayed due to COVID). I have had the honor of been reviewed by Pr. Patrick Pérez and Pr. Josef Sivic and examined by Pr. Cordelia Schmid, Dr. Hervé Jégou, Dr. Diane Larlus, Dr. Elisa Fromont and Dr. Ondřej Chum (as invited member). I have performed my PhD at Inria Rennes--Bretagne Atlantique under the supervision of Yannis Avrithis and Guillaume Gravier. During my PhD, I have performed two internships at Twitter and Google and visited the Visual Recognition Group (CVUT).
