title: Measurement of electrons from open heavy-flavor hadron decays in pp at s = 13 TeV and electrons from beauty-hadron decays in Pb-Pb at sNN = 5.02 TeV collisions by ALICE at LHC
abstract: I am deeply thankful for the opportunity I had to do this work, and for the so many wonderful things I have learned during these years. My special thanks to Marcelo, for trusting this work to me and for giving me chances to grow. My thanks to all the friends from HEPIC@IFUSP, for being around day-by-day, sharing discussions, difficult questions and life. Many thanks to Silvia for gladly receiving me at GSI twice. My special thanks to Andrea, who was my guide since the beginning of the first anal
