Research

The matter in the universe is not homogeneously distributed but instead organised within a web of highly over dense regions such as galaxy clusters and filaments of galaxies. These are surrounded by huge under dense regions - the so called cosmic voids.

I am developing new analytical, numerical and statistical tools to characterise this web of cosmic structures and to connect fundamental theories of cosmology with observational data. What motivates me and my work are the three questions at the heart of modern cosmology: What is dark matter? Why does the cosmic expansion accelerate? And what is the nature of the initial conditions that seeded today's cosmic structures?

  • A list of my publications can be found here.
  • My PhD thesis can be found here.

 

CosMomentum

I am the lead developer of the CosMomentum software package. CosMomentum allows you to evaluate theoretical predictions of various higher order statistics of cosmic random fields (such as the cumulant generating function or the probability density function of matter density, galaxy density or lensing convergence). It is publicly available on github.
