**The event was cancelled.** Abstract: Despite the hugely successful discovery of the Higgs boson at the LHC, the Standard Model of particle physics remains unable to explain many features we see in the universe. New phenomena like supersymmetry have been postulated to describe the large hierarchy of energies, the nature of dark matter, and the source of matter-antimatter asymmetry. We present the latest, most precise ATLAS measurements of the Higgs boson mass, charge-parity, and couplings to other particles, which are sensitive to many well-motivated models of new physics. Over the next 15 years, the High-Luminosity LHC will provide a much larger data sample enabling even higher precision. A new all-silicon Inner Tracker, which will cover a much wider acceptance than the current tracker, is being developed to cope with the huge radiation, data rates, and occupancy. The immense progress, challenges, and opportunities of this detector upgrade are discussed. About the speaker: Eric Feng is a Marie Curie COFUND Fellow at CERN working on the ATLAS experiment at the Large Hadron Collider. Before this he was a Wigner Fellow at Argonne Laboratory. He received his Ph.D in physics at the University of Chicago, and his bachelor degrees in Engineering Physics and in Mathematics at Berkeley. His research focuses on measurements of the Higgs boson properties to probe new phenomena, and the ATLAS Inner Tracker upgrade for the High-Luminosity LHC.
