Having a background in experimental neurophysiology, I mainly work on the analysis of data produced in this field. This work can be split into three broad categories – with associated keywords linking the task to specific statistical methodologies :

  • Spike sorting – dimension-reduction, clustering, classification, Gaussian mixture models, EM algorithm, MCMC. All that is now explained in a short film on YouTube.
  • Spike train analysis – point process / counting process, conditional intensity estimation, nonparametric estimation, smoothing spline, goodness of fit tests, Donsker theorem.
  • Calcium imaging – Poisson regression, variance stabilization, parametric / nonparametric models, image segmentation.

In every project I try to implement what is now commonly called the reproducible research paradigm – that I prefer to call the reproducible data analysis paradigm. I am not a developer of the tools making the implementation of the paradigm possible but a daily user of them.


  • Within Paris-Descartes University I'm collaborating with:
    • Yves Rozenholc on the development of nonparametric methods for the analysis of fluorescence calcium measurements.
    • Avner Bar-Hen on the development of goodness of fit tests for counting process models.
  • In the rest of the World I'm collaborating with:
