About

I work on problems in cosmology and computational science, with a focus on modelling complex systems and extracting meaning from confusing data.

My interests lie in the intersection of cosmology · bayesian statistics · artificial intelligence · machine learning

Work

  • Cosmology modelling
  • Statistics driven analysis
  • Data + inference pipelines

Selected Work

— Bayesian power spectrum estimation with modelling of systematic effects in delay-fringe rate space Gibbs-sampling power spectrum estimator for the EoR (Epoch of Reionization) signal in radio interferometric visibilities. Jointly samples the EoR signal, foreground amplitudes, multiplicative antenna gain systematics, and the EoR delay power spectrum — all within a single self-consistent Bayesian framework.

— 21 cm – Galaxy Cross-Correlation: Uncertainty Budget Forecasting the detectability of the 21 cm × galaxy cross-power spectrum during the Epoch of Reionization, following the framework of La Plante et al. (2023).
