I am a cosmological modeler working at the interface of theory and observations, looking for hints to (hopefully!) answer the above questions.
My research combine perturbative approaches, i.e. perturbation theory (PT) and the effective field theory of large-scale structure (EFTofLSS), with novel statistics to build accurate and roburst forward models that yield optimal Bayesian inference and comparison of cosmological parameters and models.
