Talks

During my PhD, I have presented my research at a few international cosmology conferences:

  • DarkMap — Mapping the Dark Universe (Budapest, 2025)

  • Cosmology from Home (online, 2025). talk available here

  • Relativistic Effects and Novel Observables in Cosmology (Geneva, 2024)

  • Cosmology from Home (online, 2024). talk available here

Codes

I am a co-developer of the PhaseSpaceDTFE.jl julia package for evaluating multistream density and velocity fields from cosmological N-body simulations. The code is hosted at this repository and registered with the DOI 10.5281/zenodo.16637560. Have a look at the documentation if you’re interested in using the code in your own research, and do not hesitate to reach out to the developers if you have any questions!
