Panagiotis Bellos obtained his Ph.D. from the University of Athens in 2020. His research focus on the study of the Higgs boson with the ATLAS detector. He was involved in several analyses in the H->ZZ*->4l channel, including the Higgs boson decay width and differential cross sections measurements as well as the search for new resonances. He has also worked in electron identification and in the MicroMegas group of the New Small Wheel. Currently he is fellow researcher in the Particle Physics group of the University of Birmingham, studing exotic decays of the Higgs boson.
