After the discovery of the Higgs boson, there have been a lot of ideas on how to best present measurements of the properties of the Higgs boson to learn the most about the Standard Model and physics beyond the SM.
I will give an overview of the current ideas and their implementation in the ATLAS experiment as well as show first results. Then I will focus on the efforts in the H -> WW* decay channel and discuss where the input from H -> WW* is most needed for our knowledge of the Higgs boson. I will explain the challenges of performing these measurements and show first results in Run 2.
I will conclude by giving and outlook on the measurement of differential cross sections as well as on constraining new physics via global fits of effective field theories.
