I am the PDRA in Cosmic Microwave Background Research for the UK branch of the Simons Observatory (SO), the next experiment to search for signs of cosmic inflation, which is currently the most widely supported theory of the big bang. As part of the analysis team at Oxford, I am developing a key science pipeline to look for primordial gravitational waves, the elusive “stretchmarks” of inflation, within the polarised microwave background.
Since 2020, during my Ph.D. at SISSA, Italy, I have been an active member of SO and wondering how to best remove the veil of Galactic foregrounds, which is a well-known threat to any unbiased measurement of primordial gravitational waves. As an independent project, I have applied machine learning to real data from the Planck satellite to investigate the era of cosmic reionisation. I am currently involved in SO’s early science data analysis, working on time stream analysis, power spectrum estimation, and cosmological inference.
My other interests are the cosmic large-scale structure and statistics. Specifically, my current work relates to the kinematic Sunyaev-Zel'dovich effect that tells us how baryonic matter spreads around galaxies, as well as statistical approaches to internal data consistency and model comparison.
