About me

moi2_smallHi. I’m Matthieu Dubois. Welcome on my personal webpage.

I’m curious and like to solve problems in innovative and unique ways. I’m also eager to learn and acquire new skills. I’ve been doing this in scientific research for many years. I’m now facing new challenges as Project Manager at Twipe, a young company that develops digital publishing suites for newspapers and magazines.

In 2009-2013, I worked on how our brain integrates sensory information coming from multiple sources, within a sense (e.g. the different letters of a written word, of the syllables of a spoken sentence) and between senses (e.g. a sentence eared and read at the same time). The approach I used is mostly psychophysical. I measured thresholds on human observers and compared them to the optimal performance predicted by Signal Detection Theory. This line of research has been initiated in 2009, during a post-doctoral stay at New York University, USA, with Denis Pelli and David Poeppel. I pursued it in Brussels, Belgium, at the Université Libre de Bruxelles.

Before this, I got a Ph.D. in cognitive psychology from the Catholic University of Louvain, in Belgium, in 2008. I investigated  visual processes that takes place during reading and wether (and how) they are affected in developmental dyslexia. To do it, I used a mathematical model of visual attention (dubbed TVA), developed at the Center for Visual Cognition of the University of Copenhagen. Together with Søren Kyllingsbæk, I applied this model for the first time on children data to describe visual attention deficits in dyslexic children. I then spent one year as post-doctoral researcher in Grenoble, France, pursuing my work on dyslexia with Sylviane Valdois.

I like to learn new tools to tackle the problems at hand. During my Ph.D., I got introduced by Pierre Lafaye de Micheaux to quantitative analysis and computer simulations using R. As a post-doctoral researcher in Denis Pelli Lab, I learned to do psychophysics in MATLAB and the psychtoolbox. I also use eye movement monitoring with the Eyelink.
