The Standard Model Effective Field Theory (SMEFT) is one of the most
promising tools for precision based discoveries at the LHC. Calculation in
the SMEFT are often fraught with inconsistencies in the power counting
expansion. The recent geometric reformulation of the SMEFT (geoSMEFT) allows
us to perform calculations at NLO in the SMEFT expansion, and in many cases
all orders in the SMEFT expansion.

In this talk I will introduce basic idea behind effective field theories,
discuss the SMEFT and its use at the LHC, and demonstrate how the geoSMEFT
is formulated. I'll then demonstrate some of the recent applications of the
geoSMEFT and discuss how it may help elucidate the theory error associated
with the truncation of the SMEFT expansion.
