ATLAS Experiment

Professor Mallik and her group joined the ATLAS experiment with SLAC at the end of 2006. She and her group were involved in the Silicon Pixel detector, with part of the group resident at CERN and fully involved in the DSP part of the project. They then participated in the liquid Argon Calorimeter (LAr), in Phase 1 trigger upgrade and LAr operation leadership. The group currently has a central role in the High Granularity Timing Detector (HGTD), part of LAr group, for the Phase 2 upgrade. The group's physics interests lie in the Higgs and Beyond Standard Model (BSM) physics analyses. They have/had critical roles in higgs --> b-bbar and Vh resonance searches. They are also involved in Dark Energy search and Precision measurement of the Weak mixing angle.
