I have been involved in the field of high energy physics and more specifically the efforts of the CMS experiment since the start of my academic career. The focus during most of this time was dedicated to my current main field of interest, the study of the 2012 discovered Higgs boson. During my Ph.D. in Germany, I was involved in the CMS search for Higgs decays into muons, the first analysis claiming evidence for this extremely rare process and thus the Higgs coupling to second generation fermions. I also was one of the main researchers behind the first CMS search for Di-Higgs processes in final states with multiple leptons and hadronic taus, providing one of the leading constraints on the trilinear Higgs self coupling. This effort continued also in my time as a research fellow in Estonia, with further involvement in the overall CMS Di-Higgs effort continuing to this day. This involvement as an active member of the Di-Higgs community includes the development of tools and studies used by other Di-Higgs analyses, work on the combination and reinterpretation of different analyses, as well as the theoretical interpretation of Di-Higgs results in an EFT context. Here I am also currently serving as one of the CMS Di-Higgs contacts, coordinating all Di-Higgs related analysis within CMS. For the analysis of Higgs decays I have also been working on reconstruction techniques for tau-leptons using modern machine learning methods. At the moment I am leading the CMS analysis efforts in Estonia, preparing our group for analysis in LHCs Run 3.
