**Research engineer (biological data analyst), CNRS** Laboratoire de Psychologie Cognitive (UMR7290) CNRS & Aix-Marseille University, France **Honorary Senior Research Fellow** Queensland Brain Institute The University of Queensland, Australia **Academic pages** *- LPC page (*[https://lpc.univ-amu.fr/fr/profile/dufau-stephane)](https://lpc.univ-amu.fr/fr/profile/dufau-stephane) \- *QBI page* ([https://qbi.uq.edu.au/profile/16159/stephane-dufau)](https://qbi.uq.edu.au/profile/16159/stephane-dufau) *- ResearcherID* (Publons, [web](https://www.webofscience.com/wos/author/record/1811425), including satatistics and citation metrics from Web Of Science Core Collection, Clarivate, & peer-review activity), *- OrcID* ([web](http://orcid.org/0000-0002-2692-2084)), *- Scopus Author* ([web](https://www.scopus.com/authid/detail.uri?authorId=16833439500), including statistics and citation metrics from Scopus, Elsevier), *- Google Scholar* ([web](https://scholar.google.fr/citations?user=kzJ_yRcAAAAJ&hl=fr&oi=ao), including citation metrics from Google) *- ResearchGate* ([web](https://www.researchgate.net/profile/Stephane_Dufau), social scientific networking) ### POSITION - Currently on a long-term scientific mission at QBI, UQ, Australia (2022/2023) - Research engineer in [Laboratoire de psychologie cognitive](https://lpc.univ-amu.fr/) at [Centre National de la Recherche Scientifique](http://www.cnrs.fr/) (CNRS) and [Aix-Marseille University](http://www.univ-amu.fr/), France. I am in charge of the [Experimentation and Analysis Service](https://lpc.univ-amu.fr/fr/service-experimentation-analyse) ### BIO After a degree in [physics](https://sciences.univ-reunion.fr/presentation) (1997) and [biomedical engineering](https://www.univ-tlse3.fr/master-electronique-energie-electrique-automatique-parcours-radiophysique-medicale-et-genie-biomedical) (medical imaging, 1999), I worked as a [database manager](https://en.wikipedia.org/wiki/2nd_Marine_Infantry_Parachute_Regiment). In 2001, I was appointed by CNRS as a [software engineer](http://metiersit.dsi.cnrs.fr/index.php?page=ficheemploitype&codeEmploi=E2C45&idFamillePro=20&codeBAP=E&codeFamille=C) in a cognitive psychology lab (~20 permanent researchers). I mainly analysed data and wrote computer programs for the different recording devices I managed ([eletroencephalography](https://en.wikipedia.org/wiki/Electroencephalography), [ocular movements](https://en.wikipedia.org/wiki/Eye_movement), [behavior](https://en.wikipedia.org/wiki/Human_behavior)). I started to be interested in the various research topics the lab I worked in covered with a particular focus on [psycholinguistics](https://en.wikipedia.org/wiki/Psycholinguistics). While still working, I enrolled in a [PhD program in neuroscience](https://ecole-doctorale-62.univ-amu.fr/), which was completed it in 2008 ([abstract](http://www.sudoc.fr/131402390)), 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 language and cogntion. ### ### GRANTS *PI, co-PI* \- **Bionics Challenge** 2023: Pilot study of non-invasive wearable devices in the video-EEG epilepsy monitoring unit, PI: Aileen McGonigal (University of Queensland, Australia; 40,000 A$) \- **Convergences AMPIRIC** 2021, Finger-tracker, PI: Stephane Dufau (3000 EUR) \- **DFG** 2016-2021: The role of morphemes during reading development.
