In my PhD period, as indirect searches for BSM signature, I measured the time-dependent CP asymmetries in the flavour-changing-neutral-current decays (b->d and b->s) of B mesons at the luminosity-frontier Belle experiment at KEK in Japan. After my PhD, I then joined the energy-frontier LHC-ATLAS experiment at CERN in Switzerland. Regarding my work on science in ATLAS, I performed a number of direct searches for Supersymmetric Particles and Dark Matter since the start of LHC, and for Long-Lived Particles more recently. I have also been active in the Higgs-pair production studies aiming for Higgs self-coupling measurements, which is a newly-flourishing area of Electro-Weak & Higgs physics towards the future High-Luminosity LHC, for complete understanding of the Higgs mechanism and the nature of the vacuum in the universe. At QUP, I develop advanced analysis techniques including Machine Learning, and apply them to data analyses in order to efficiently achieve science outputs. Regarding my work on technology, I have been involved in the development & operation of the ATLAS trigger system in order to exploit the full BSM-discovery potential as well as to achieve the wide range of the energy-frontier ATLAS physics program. For the High-Luminosity LHC, I contribute to the mass-production of radiation-hard silicon modules and quality assurance & control in the context of the ATLAS Inner Tracker Upgrade project.
