  In this talk, I discuss theoretical advances in understanding the properties
of the Higgs boson and the implications for models of electroweak symmetry
breaking. I begin by reviewing some of the recent progress in Standard Model
calculations for Higgs boson production and decay rates, followed by a
lightning tour of the use of effective field theories in the search for new
physics in the Higgs sector. I end with a discussion of the complementarity of
precision Higgs coupling measurements and direct searches for heavy particles
for the discovery of Beyond the Standard Model physics in the electroweak
sector.
