Scientific summary

My main research focus is on multivariate data analysis and statistical inference of brain function from functional MRI. I develop algorithms and models to study the correlations in the fluctuations of neural activity observed across the brain, i.e. functional connectivity. For inference on group data, I introduce explicit models of spatial and functional variability.

I work on group-level multivariate spatial analysis of resting-state data (Spatial ICA and spatial structured decompositions). I also use Gaussian graphical models to study the covariance structure of brain activity. Finally, I work on multivariate analysis to map the neuronal coding of cognitive processes across subjects in machine-learning settings.

In addition, to bridge the gap between algorithm research and applications, I have been contributing to building a general-purpose tool stack for computational science using the Python language. My effort is shared between software development and improving communication and cooperation between scientific software projects and users.
