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. My recent work highlights several promising methods that will be used for SO’s science data analysis, which is expected to start in late 2024. As an independent project, I have applied machine learning to real data from the Planck satellite to investigate the era of cosmic reionisation.
My other interests are the cosmic large-scale structure and statistics. Specifically, I am working on a novel estimator of angular power spectra from source catalogs, as well as Bayesian approaches to data robustness and model comparison.
