Domaines de recherche


After a degree in physical sciences (1996) and applied physics (Radiation and medical imaging, 1999), I worked as a database manager during my national service and was appointed in  2001 by CNRS as a software engineer in a cognitive psychology lab (~20 permanent researchers). I mainly analysed data and wrote computer programs for the different recording devices I managed (eletroencephalography, ocular movements, behavior). I started to be interested in the various research topics the lab covered with a particular focus on psycholinguistics. While still working, I enrolled in a PhD program in neuroscience, which was completed it in 2008, and competed for a research engineer position at CNRS I obtained in 2010. I am since a biological data analyst. I am particularily interested in developing novel methods of data acquisition and data processing for the study of cogntion.
