A theoretical <particle physicist> who coauthors the Particle Data Group review of the <electroweak interaction> with <J. Erler>. It connects measured observables to <renormalization>, radiative corrections and fits of <Standard Model> parameters. Comparing many precision observables with one consistent theory makes small departures from its predictions a quantitative constraint on proposed new interactions.<Electroweak Model and Constraints on New Physics by J. Erler and A. Freitas (2024)>[Sections 10.2, 10.6 and 10.7: radiative corrections, global fits and constraints]{ref}
