I am a French research scientist specialized in sleep and dreaming.
I obtained in December 2017 a PhD in neuroscience, with honors, from Lyon 1 University. My doctoral project was conducted with Dr. Perrine Ruby, and aimed at understanding how and why we sometimes recall our dreams and sometimes forget them, using several approaches such as EEG, fMRI and dream content analysis. Since Feb 2018, I am working with Pr. Matthew Walker, at U.C Berkeley, studying the impact of sleep deprivation on the brain.
I also have a strong research interest in statistics and signal processing. I am the (co)-founder of two Python open-source packages which are currently under development: Sleep (sleep scoring and analysis, part of the Visbrain suite) and Pingouin (statistics).

I am very happy to introduce my new open-source Python package, called Pingouin. Pingouin is born out of a personal need to reduce and simplify the number of steps in my statistical analyses. Pingouin provides simple and easy-to-grasp functions for computing ANOVA, pairwise post-hocs and effect sizes. Pingouin is based on Pandas and therefore allows to leverage the power of this latter. Learn more on the documentation or check the code on GitHub.
I am thrilled to announce that I will join Pr. Matthew Walker at U.C Berkeley (USA) for a two-years post-doctoral position starting February 2018.
