Description
With the discovery of the Higgs boson, the Standard Model is complete. 
Yet the SM is itself an incomplete description of nature.  One strategy to 
move beyond this model is to search for new processes through SM 
measurements.  An effective field theory describes the impact of 
high-scale processes as small deviations from the SM in orders of the 
inverse scale of new physics.  A complete fit of the EFT operator 
coefficients provides a generalized probe for new physics.  I discuss 
recent progress in such fits, focusing on the contributions from 
precision Higgs and electroweak measurements.
