The Large Hadron Collider (LHC) has collected a sizable dataset of proton-proton collisions at a center-of-mass energy of 13 TeV, providing our first detailed glimpse of the TeV energy scale.  The LHC is projected to collect a factor of 30 more proton collisions by 2035. I’ll provide a theorist’s perspective on what we’ve learned so far, and what we might learn next.  The LHC has discovered the long-sought Higgs boson, but no other new particles, demonstrating that the Standard Model of particle physics seems to describe physics at the TeV energy scale.  The next step will be to perform measurements of Standard Model processes, and to see if it’s possible to produce and discover new particles.  I’ll highlight another strategy for how we can use the LHC to look for new physics.  New particles may not appear directly, but instead may leave subtle imprints on the properties of known particles, which can be revealed through careful analysis of existing and future data.  I’ll also highlight how proposed future colliders can extend the physics program of the LHC to higher energies and higher precision.
