I have been a collaborator of the ATLAS Experiment since 2006. The experiment is located at CERN, Geneva, and has been studying proton-proton collisions at extreme high energies produced by the Large Hadron Collider (LHC). Using the data collected by the ATLAS detector since 2009, the Harvard ATLAS group has made precise measurements of the Standard Model processes and searched for new particles predicted by theories beyond the Standard Model.
Starting 2015, the LHC is colliding protons at the center-of-mass energy of 13 TeV. With the data collected with ATLAS, my group is working on searches for Dark Matter particles and for supersymmetric partners of quarks and gluons.
Between 2009 and 2011, I was a collaborator of a Dark Matter experiment called LUX, which stands for Large Underground Xenon. As the name suggests, it used a large amount (300 kg in total) of liquid xenon, located in an underground cavern. The goal of the experiment was to detect the Dark Matter particles, which make up >80% of the mass of the universe. The experiment was built in the Homestake gold mine, where Ray Davis built his solar neutrino experiment 40 years ago.
I worked on the BABAR Experiment between 1996 and 2008. The experiment studied the phenomenon of CP violation using the PEP-II e+e− collider.
