I will present results from an independent reanalysis of the first-year DESI full-shape data using an effective field theory (EFT) full-shape model. Compared to the collaboration analysis, we incorporate the galaxy bispectrum, which improves parameter constraints and ensures the perturbativity of the EFT expansion. These analyses deliver some of the tightest constraints to date on ΛCDM, dynamical dark energy, neutrino masses and primordial non-Gaussianity. I will also discuss recent theoretical developments, most notably a consistent one-loop EFT bispectrum calculation, that lead to substantial gains in constraining power compared to previous analyses. Finally, I will present results obtained using simulation-based priors, which efficiently incorporate small-scale information into the DESI analysis.
