About me
I am currently a PhD student in Radio Cosmology at Jodrell Bank Center for Astrophysics (JBCA) at University of Manchester (UoM) under supervision of Phil Bull. Here, my work has been focused on developing a Bayesian mapmaking formalism for 21cm interferometers. I originally started my PhD at Queen Mary University of London, whereafter our research group relocated to Manchester. Before that, I was an MSc student at Aarhus University under supervision of Steen Hannestad and Thomas Tram in numerical Cosmology where I did forecasts for SKA using MontePython based on non-standard cosmological models.
My main passion-project outside of research is running EquiTea, a monthly forum at the Jodrell Bank Centre for Astrophysics (JBCA) for Equity, Diversity and Inclusion. We often have invited speakers to lead the sessions and it is a great space for open discussions and with positive feedback from both PhD students and staff.

Research
I am specifically interested in the early Universe and the Large Scale Structure of the Universe.
Currently, I work with 21-cm Epoch of Reionisation. My main project during my PhD has been developing a Bayesian full-sky mapmaking formalism for 21-cm interferometer visibilities from instruments such as (but not limited to) the Hydrogen Epoch of Reionization Array (HERA). Keywords would be: Gaussian constrained realisations, Gibbs sampling, EoR, diffuse foregrounds and spherical harmonics. In the process I have taken a special interest in investigating excess radio backgrounds such as the ARCADE2 and LWA results, which, besides being essential to eventually uncover the underlying 21-cm signal, also has the possibility to unlock new physics! Other topics that have caught my interest are CMB B-mode polarisation and other LIM tracers of the early Universe and the EoR, especially in the context of joint analysis with 21-cm experiments.
