Research Interests

I am interested in constraining cosmological parameters by using large-scale structure data from galaxy surveys such as BOSS and DESI (of which I am an active member). Therefore, I use information obtained from galaxy clustering, the Lyman-alpha forest and quasars. In this context, I analyse the baryon acoustic oscillations, compute likelihoods to constrain cosmological parameters and perform tomographic redshift bin analyses of the data. 

In addition to large-scale structure data analysis, I am interested in developing and testing the novel likelihood-free approach on CMB data from the Planck survey.
