My research interests are mostly focused on the dynamics of large scale structures, their statistics and their correlation with the cosmic microwave background.
Notably, I have strong interest in the peculiar velocities of galaxies. You can get more explanation here. I have published a python code and a dataset of reconstructed peculiar velocities of our Local Universe (here).
My other interest is in cosmic voids (here), large relatively underdense region of our Universe. Compared to collapsed structures such as cluster of galaxies, they have much simpler dynamics and are dominated by dark energy. This makes them interesting laboratories both to study dark energy and the statistics of initial conditions.
I have co-developped a website to provide the astronomical community with calibrated 3d reconstruction of cosmic flows, alongside some easy tools to access it directly from a web browser. Check it out at here.
