Abstract: This thesis describes two precision measurements of Higgs boson to tau lepton decays, using the CMS detector at the CERN LHC. Two analyses have performed using two different analysis goals/schemes. The first using the "Simplified Template Cross Section" scheme, the second a more general differential analysis scheme. Both analyses use the complete Run 2 dataset of the LHC. Developments to use Higgs to taus as a final state to search for high mass resonances in boosted topologies are also discussed, including adaptation of a machine learning technique for specially reconstructed boosted Higgs to tau topologies.
